Tristan Albatross Diomedea [exulans] dabbenena is the most genetically distinct of the five taxa that form the Wan dering Albatross superspecies, and has been listed as Endangered. It breeds only on Gough and Inaccessible Islands in the Tristan da Cunha group, central South Atlantic Ocean. The entire breeding population was surveyed during 1999-2000. A mid-September survey at Gough Island recorded 1,129 chicks, equivalent to an annual breeding effort by approximately 1,500 pairs. Only one chick was present at Inaccessible Island in 1999, and another pair laid an egg in 2000. The annual breeding effort at this island has not exceeded three pairs since the 1950s. None were found during an incomplete survey at Tristan, where the species bred in the past, but birds were seen flying over the island. A complete survey and attempts to promote recolonization of Tristan are warranted. Breeding success at Gough Island averaged 63%, and no birds that bred successfully attempted to breed the following year. Breeding success was greater and less variable in a large colony at Gonydale than at a peripheral colony at Tafelkop. Young birds returned to the island after 3-4 years (4-5 years old), and the modal age of first breeding was 8 years, with some individuals breeding as young as 6 years. Most chicks (81%) recruited to their natal colony, but some recruited to colonies up to 3 km from their natal site. Among adults, fidelity to partners and breeding colony was high. Of nine birds recovered away from the island, at least four were killed by longline fishing. Despite its known mortality on longlines, the Gough Island census exceeded demipopulation estimates from the 1970s and early 1980s, possibly due to incomplete coverage by previous surveys and a poor breeding season in 1998. Given the lack of evidence for a population decrease, Tristan Albatross should be listed as Vulnerable. It is the third rarest albatross species, however, and its population size warrants monitoring. We provide guidelines for repeatable censuses at Gough Island.

Between October 1991 and February 1992 field surveys on the status of parrots in the North Moluccas were conducted on Obi, Bacan and Halmahera, with principal focus on three significantly traded species, White Cockatoo Cacatua alba, Chattering Lory Lorius garrulus and Violet-necked Lory Eos squamata. Variable circular plots and variable-distance line transects were used to estimate minimum and maximum population densities at each of 18 sites. C. alba and L. garrulus preferred forest, the former largely confined to lowlands to 600 m, the latter occurring more in hilly areas to at least 1,300 m. E. squamata frequented all habitat types, being commoner in disturbed habitats though rarer at higher altitudes. Minimum populations (the first two being global) were 50,000, 46,000 and 66,000 respectively, and minimum estimated captures in 1991 5,120, 9,600 and 2,850, indicating overexploitation of the first two species. To ensure sustainability, total annual catch quotas should be reduced to 1,710, 810 and 1,590 respectively and allow for fair division between islands. Training, enforcement, monitoring, research and habitat conservation are all needed.

The Central Pacific Conservation Area contains one of Costa Rica's two viable, but threatened Scarlet Macaw Ara macao populations. For 14 years (1990–2003), we monitored the size of this population. Non-linear models fitted to 1990–1994 observations revealed seasonal and long-term changes in population size. The peak of annual population size occurred in August, with a cyclic range of about 90 birds between the lowest and highest points of the annual cycle. The best model also revealed a decline in population size of approximately eight birds counted per year or 4% of the total population per year (1990–1994). Young-to-adult ratios calculated for the month of August during this study fluctuated around a baseline that averaged 6.1% a year (1990–2003). These ratios exceeded 8% for three different years (1995, 1996 and 2000). All three of these “good” recruitment years occurred after management began, and two of them were associated with zealous anti-poaching efforts that ultimately could not be sustained. After intensive management practices began in 1995, the August counts increased by about 37 individuals in two years (1995–1996) to an average 243 individuals, which remained almost constant up to 2003. Management practices included creation of a local conservation organization that coordinated environmental education, artificial nest construction, networking among stakeholders and with governmental authorities, and artificial and natural nest protection. Although Scarlet Macaw conservation efforts have been inconsistent since 1997, our study demonstrates that collaborative conservation by local stakeholders increased the population of this threatened species in 1995–1996, and from 1996 to present the population has sustained itself.

In the Karoo region of South Africa, eagles nesting on high voltage power pylons are responsible for frequent short-circuits or faults, which reduce the quality of commercial power supply and escalate costs to the country’s energy supplier, Eskom. Between 2002 and 2006 we conducted annual helicopter surveys of eagle nests on 1,400 km of power line and located 139 large nest structures, making up 96 eagle territories occupied by three species: Martial Eagle Polemaetus bellicosus (66 pairs), Verreaux’s Eagle Aquila verreauxii (13 pairs) and Tawny Eagle Aquila rapax (17 pairs), and detailed 357 pair-years of breeding activity, including 241 breeding attempts. Roost sites and active nests were associated with line faulting, and more so at particular pylon configurations. We developed a three-step management plan to reduce eagle-related faulting while still accommodating eagles on the power lines: (i) all (potentially) problematic nests were relocated from high-risk positions above the power conductors, to specially provided platforms placed below the conductors; (ii) perch deterrents were installed above the conductors on all nest pylons and on high-risk pylons up to 10 structures on both sides of each nest tower; and (iii) the welfare of the eagles was monitored before and after management. In this way, line faulting was reduced on actively managed lines by > 75%, with no obvious deleterious effects on the eagle population. The study revealed that: (i) power lines can support substantial breeding populations of threatened large raptors, (ii) these birds can be a source of commercially significant line faulting, and (iii) nest relocations and perch deterrents are effective in reducing faulting without negatively impacting eagle populations.

Some 2,000 orphaned chicks of African Penguins Spheniscus demersus were hand-reared and released back into the wild on Robben and Dassen Islands following the Treasure oil spill in June 2000. Of these chicks, 1,787 were flipper banded. This paper reports on the subsequent survival rate and breeding success of those individuals seen on Robben Island from 2001–2006. Survival to breeding age and their subsequent breeding success of hand-reared chicks was no different from that of naturally-reared chicks. Over a four-year period, pairs where at least one partner was a hand-reared chick produced an average of more than 1.6 chicks per year. Combining the data on survival with that on breeding success indicates that 1,000 hand-reared chicks will produce around 1,220 chicks themselves over their lifetimes, making this a worthwhile conservation intervention.

In late 2000, five sanctuaries were established on the mainland of New Zealand for the express purpose of protecting populations of five kiwi Apteryx spp. taxa belonging to three species. Conservation management was undertaken at a landscape scale (10,000–20,000 ha) in each sanctuary to improve recruitment of kiwi. This was done by controlling introduced mammalian predators (especially stoats Mustela erminea), and/or by removing eggs and chicks from predation risk, and returning subadults when they were big enough to cope with stoats. Population modelling of the first five years of the sanctuary programme indicated that kiwi numbers in all five sanctuaries would increase as a result of the management. Calculated population increases varied from 0.6% per year at Okarito to 11.3% per year at Moehau, even though predator trapping was more intense at Okarito. The variation from site to site was explained by the widely different inherent productivity of the various kiwi taxa; widely different rates of adult mortality due to the presence or absence of dogs Canis familiaris and ferrets M. furo, the main predators of long-lived adult kiwi; and, local forest conditions affecting predator-prey cycles, and the density of stoats. As a result of this analysis, the management in four of the five sanctuaries has since been modified to try to achieve better overall gains for kiwi within the same operating budget.

Pelagic seabird populations have declined strongly worldwide. In the North Atlantic there was a huge reduction in seabird populations following the European colonization of the Azores, Madeira and Canary archipelagos but information on seabird status and distribution for the subtropical region of Cabo Verde is scarce, unavailable or dispersed in grey literature. We compiled and compared the historical and current distribution of all seabird species breeding in the Cabo Verde archipelago, updated their relative abundance, investigated their inland habitat preferences, and reviewed their threats. Currently, the breeding seabird community in Cabo Verde is composed of Bulwer’s Petrel Bulweria bulwerii, White-faced Storm-petrel Pelagodroma marina aedesorum, Cape Verde Shearwater Calonectris edwardsii, Cape Verde Storm-petrel Hydrobates jabejabe, Cape Verde Petrel Pterodroma feae, Boyd's Shearwater Puffinus lherminieri boydi, Brown Booby Sula leucogaster, and Red-billed Tropicbird Phaethon aethereus. One breeding species is currently extinct, the Magnificent Frigatebird Fregata magnificens. The relative abundance of Cape Verde Shearwater, Boyd’s Shearwater, Cape Verde Petrel, and Cape Verde Storm-petrel was determined from counts of their nocturnal calls in Santo Antão, São Vicente, Santa Luzia, Branco, Raso and São Nicolau. Cape Verde Petrel occurred only on mountainous islands (Santo Antão, São Nicolau, Santiago, and Fogo) from mid-to high elevations. Larger species such as the Cape Verde Shearwater and Boyd’s Shearwater exhibited a wider distribution in the archipelago, occurring close to the coastline but at lower densities on populated islands. Small procellariforms such as the Cape Verde Storm-petrel occurred at high densities only on rat-free islets and in steep areas of main islands where introduced cats and rats are unlikely to occur. The main threats to seabird populations in Cabo Verde range from predation by introduced predators, habitat alteration or destruction, and some residual human persecution.

A preliminary survey for Gurney's Pitta Pitta gurneyi was undertaken at five sites within the species' historical range in the Tanintharyi (Tenasserim) Division of Myanmar from 14 to 24 May 2003. During the surveys, Gurney's Pittas were heard and/or observed at four sites with a maximum of 10–12 pairs recorded at one site. Birds were encountered in logged primary and secondary forest below 100 m on flat ground, sometimes less than 10 m from forest edge. All encounters were within 2 km of the main trans-Tanintharyi highway. Landsat satellite imagery was used to map remaining lowland forests and Gurney's Pitta habitat in the Tanintharyi Division. Our analysis demonstrated that only 4,705 km2 of lowland forest remain with about 3,496 km2 in flat areas with slopes < 10°. On the basis of previously reported population densities, these habitats may support a population of 5,152–8,586 pairs. Much of the remaining habitat is restricted to small and fragmented patches < 1 km2 in area. The five largest patches have a total area of 1,431 km2 and range in size from 137 to 467 km2. This survey demonstrated that Gurney's Pitta still occurs within its historical range in Myanmar, although probably not at any of the historical collecting localities visited. The global population of Gurney's Pitta is at least 100% greater than the latest published estimate. This survey has also shown that the Gurney's Pitta population in southern Tanintharyi Division is under pressure from forest conversion to oil palm. Contrary to the situation in neighbouring Thailand, sufficient forest remains to establish landscape level protected areas covering a broad ecological continuum. Securing populations of Gurney's Pitta within either expanded or entirely new protected areas must be the best chance for the species and the Sundaic flora and fauna of which it is part.

Nest-site selection by the sympatric Great Hornbill Buceros bicornis, Wreathed Hornbill Aceros undulatus and Oriental Pied Hornbill Anthracoceros albirostris was investigated in a lowland tropical forest in Arunachal Pradesh, north-east India during 1997–2000. Information on two nests of Rufous-necked Hornbill Aceros nipalensis in higher-elevation forests is also presented. All species nested in live trees of three tree genera, 83% (n = 36) in Tetrameles nudiflora, an emergent deciduous softwood, relatively common in lowland foothill forests. No difference was recorded in nest-tree species or nesting habitats of sympatric hornbills, but there were a few differences in structural characteristics of nest-trees. Cavity size was the main variable separating the three species. Great Hornbills used larger cavities while Oriental Pied Hornbills used smaller cavities closer to riverine areas. Nesting was attempted at 64% of known sites and successful fledging of chicks was 80% overall (n = 72 nests, pooled over 4 years). Nest-trees in disturbed habitats near human habitation were used but were often abandoned or unsuccessful and 50% of all nest-trees were inactive by the end of the study. Potential large nest-trees had a density of 5.9/ha, that of the two most used species was 1.3/ha, and minimum nest densities of all three species was about 1 pair/km2. Interference competition for nest-sites was not observed, despite similarity in nest-tree characteristics, low nest density and high loss of nest-trees. Nest-site availability may naturally limit hornbill populations in the area, and additional loss of nesting habitat to human activities may exacerbate limited availability of breeding sites.

Currently, renovation and thermal insulation of buildings is happening at a high rate in many European countries, driven in part by the political aim to reduce greenhouse gas emissions. Unfortunately, building renovations often lead to a loss of structures, such as accessible cavities, on which synanthropic species, for example house-nesting birds, depend. In Germany, due to legislative regulations, it is a common practice to install nest-boxes as compensation for destroyed nest sites of birds. However, studies on the efficacy of such measures remain sparse. We monitored the occupancy of 477 compensatory nest-boxes for Common Swifts Apus apus, predominantly placed on renovated prefabricated buildings in a city in Germany. We found 24.3% of the boxes occupied by Swifts. On most buildings, the number of occupied boxes was as high as or even higher than the assumed number of breeding sites prior to renovation. Furthermore, in a district where nearly all buildings had been renovated in the past 10 years, we recorded a remarkably high density of Swifts breeding in nest-boxes. Using boosted regression trees, we analysed whether eight different nest-box properties influenced box occupation probability. The number of neighbouring boxes was the most important. Additionally, box age, facade orientation, city district, relative and absolute height, and manner of installation (external/internal) also played a role. Between different nest-box types, we found only negligible differences in occupation probability. Our findings suggest that installing nest-boxes is likely to be an appropriate measure to compensate for nesting sites of Swifts lost during building renovations. Based on our results, we recommend mounting the boxes a few metres apart from each other and close to the roof edge to maximise success. Further studies should be carried out to assess whether our results and conclusions can be confirmed in other situations.

The Green Peafowl has undergone a substantial decline throughout East Asia since the turn of the century and is now reported only from a few widely scattered localities in several countries. Its plight was highlighted in the IUCN Pheasant Action Plan where it was one of the highest priorities for conservation action. Recent surveys have clarified its status and distribution in at least part of several range countries and there is patchy information from elsewhere in its range. The current knowledge of the species was reviewed at a workshop in Malaysia in autumn 1997 at which representatives from most key countries were present. The species is extinct in Peninsular Malaysia, and almost lost from Bangladesh and north-east India. There is one large population remaining in Thailand and the species is thought to be in danger of extinction in Laos. China and Indonesia hold mostly small and scattered populations although the latter does contain two large protected populations. The status in Myanmar and Cambodia is unknown, although the presence of large tracts of apparently suitable habitat in eastern Cambodia suggest that this area may hold the largest populations of the species. Conservation recommendations fall into four categories: a strategic review, assessing status and understanding ecological requirements, investigating the human-Green Peafowl relationship and considering the possibility of reintroducing the species where appropriate.

This study examines the diets of four hornbill species (Bushy-crested Hornbill Anorrhinus galeritus, Wreathed Hornbill Aceros undulatus, Rhinoceros Hornbill Buceros rhinoceros and Helmeted Hornbill Buceros vigil) common within our 9 km2 study area in the Bukit Barisan Selatan National Park, Sumatra, Indonesia. Line transects and opportunistic sampling were used over one year to collect feeding data, including the tree species and strata in which birds fed, diet items, fruit characteristics and tree crop size. Hornbills fed on 64 species. Figs, non-fig fruits and animals comprised 23.4% (n = 15 species) 51.6% (n = 33 species) and 25% (n = 16 species) of the diet, respectively. Although there was overlap among the diets of the four species, only B. rhinoceros and B. vigil had a statistically significant overlap, primarily due to high fig consumption by both species. B. vigil fed almost exclusively on figs (98.6% of the diet) and a small proportion of animals (1.4%) while 23.1% of the B. rhinoceros diet comprised non-fig fruits and animals (23.1%), with 76.9% figs. A. galeritus and A. undulatus had distinct diets with drupaceous, oily fruits comprising 66.7% and 64.4% of the diets, respectively. We found no significant relationship between the numbers of hornbills visiting fruiting trees and the characteristics of the fruit (weight, length and width). However, maximum crop sizes of diet species significantly influenced the number of feeding hornbills. Hornbill species also differed in the strata in which they fed. A. galeritus and B. rhinoceros were seen in the middle of the canopy 56% and 50.8% of the time, respectively while A. undulatus and B. vigil were observed more frequently in the upper canopy (50% and 74.3% of the time, respectively). The lower part of the canopy was used infrequently by all species. This study suggests that the four hornbill species in our study partition food resources by food type and/or feeding location.

Recent ornithological surveys of humid forest remnants in the Serra da Ouricana near Boa Nova, southern Bahia, Brazil, revealed the existence of an as yet unnoticed montane Atlantic forest avifauna. Among the 220 species recorded, 27 represent range extensions of several hundred kilometres, several others were preceded only by single or a few old, disputed records from Bahia, and at least two are undescribed taxa. A portion of this avifauna has been recorded in other mountainous areas of interior Bahia (Chapada Diamantina, plateau of Maracás), where a complex vegetation mosaic that includes patches of humid forest is found.

In addition to the two undescribed passerines, nine other threatened and thirteen near-threatened species have been recorded in the study area. Considered together with the adjoining and also highly endangered “mata-de-cipo”, forest habitats in the Boa Nova area are probably the most neglected habitats in Brazil concerning bird conservation.

Levantamentos ornitológicos recentemente feitos em remanescentes florestais úmidos na Serra da Ouricana perto de Boa Nova, sul da Bahia, Brasil, revelaram a existência nessa região de uma avifauna montícola da mata Atlântica. Entre as 220 espécies registradas, estão 27 que tiveram sua área de distribuição estendida por centenas de quilômetros, muitas outras conhecidas da Bahia apenas através de registros antigos e contestados, além de ao menos duas aves não descritas. Parte dessa avifauna foi também registrada em outras áreas montanhosas do interior da Bahia (Chapada Diamantina, Chapadão Maracás), onde se encontra um complexo mosaico de vegetação que inclui manchas de floresta úmida. Além dos dois pássaros não descritos, outras nove espécies ameaçadas e treze quase-ameaçadas foram registradas na área de estudo. Considerando-se em conjunto essa área com a vizinha “mata-de-cipo”, também muito ameaçada, pode-se dizer que os ambientes florestais na região de Boa Nova são os hábitats mais negligenciados em relação à conservação de aves no Brasil.

In 2011 the Black-faced Spoonbill Platalea minor census recorded a 22% drop in numbers from 2010, particularly at the known large coastal wintering sites. During this period, we discovered two new inland wintering sites for the species using satellite telemetry data, one located in China, where the individual followed the Yangtze river as far as Wuhan (500 km inland), and the other across the Vietnam-Cambodia border (70–200 km inland). Long periods of concentrated use of various freshwater habitats were in evidence for these two tagged individuals (China: 79 days, Vietnam/Cambodia: 91 Days) and in the latter case visual confirmation indicated a larger group of at least five individuals. The importance and potential of inland freshwater environments is highlighted towards the further conservation of the recovering population.

Our study focused on the Taita White-eye Zosterops silvanus, one of three bird species endemic to the Taita Hill forests, south-east Kenya. Formerly considered Critically Endangered, Taita White-eye has been down-listed to Endangered following the findings of this study. Between November 1998 and September 1999 we counted this species along line transects to establish their current population status and distribution in its entire range. White-eye censuses were conducted in nine forest fragments of the Taita Hills and the virtually undisturbed Mt Kasigau forest. The total global population of Taita White-eyes was estimated to be c. 7,100 birds. Mt Kasigau was shown to be the species' main stronghold, maintaining a very high density (26 birds ha−1) and holding 80% (5,600 individuals) of the entire population. In the Taita Hills forests, densities were consistently higher in the small isolated fragments than in the large ones, though the former held only a small population (3% of total). At Mt Sagala, a large isolated block where indigenous trees have been largely replaced with exotic plantation, this species was not encountered. We found no evidence of interchange between the White-eye populations on Mt Kasigau and the Taita Hills forests, probably because of the separation by a low-altitude, dry woodland habitat barrier. While prioritization for conservation action should focus more on the Taita Hills forest fragments, Mt Kasigau should be treated as fragile ecosystem which holds a huge, apparently insular population of Taita White-eyes.

South-East Asia’s bird trade is of global conservation concern as it has massively depleted wild populations of many species. Parrots (Order Psittaciformes) are especially vulnerable because they are the most heavily traded group of birds globally under the Convention on International Trade in Endangered Species (CITES) appendices. Singapore’s involvement in the global pet bird trade as a transhipment hub is well documented, particularly for parrots. Yet, much less is known about the links between its domestic and international trade. We attempt to quantify this relationship by comparing bird trade data on the CITES database with past market surveys of pet shops, complemented with semi-structured interviews with 30 parrot owners in Singapore. We report a decline in total imports and exports of CITES-listed birds in Singapore from 2005 to 2016, consistent with global trends after the European Union trade ban on wild bird imports. However, parrots continue to make up the majority of total imports; and there was a yearly increase in the percentage of parrot imports out of total imports. In addition, we report a difference in imports and exports of 54,207 CITES I, II and III listed birds into Singapore i.e. birds imported but not re-exported. A substantial proportion of these birds were possibly channelled into the domestic pet trade or used as breeding stock. Interviews with parrot owners confirmed the growing demand and popularity of parrots and particularly of larger species. We conclude that the domestic demand for parrots may have been previously underestimated, and make recommendations to manage Singapore’s international and domestic pet bird trade such as implementing a licensing and records system to track the movement of birds.

Climate change is predicted to have serious impacts on the conservation status of numerous species of birds, particularly low-density, range-restricted species occupying narrow habitats. One such species is the globally “Endangered” Sokoke Scops Owl Otus ireneae that currently survives in just two or three small pockets of forest in coastal Kenya and north-eastern Tanzania. We assessed the potential impact of changes in future climate on this species using predictive niche modelling. Distributional data were obtained from various published and unpublished sources, and field surveys. Maximum Entropy (Maxent) was used to model the current distribution of Sokoke Scops Owl. A general circulation model was used to predict the distribution of this species in 2080. This scenario predicts a southward shift in the future distribution of this species in Kenya and a complete disappearance from the Usambara mountains in Tanzania, with a concomitant 64% reduction in areas of high environmental suitability. Considering the isolated nature of the forest fragments in which this owl survives and the sea of inhospitable human-modified habitat which surrounds these fragments, the future conservation prospects of this species are bleak. Close monitoring of the species is strongly recommended and potential conservation interventions are discussed.

Birdwatching has become a global pastime and a driving force for conservation. Because of China’s economic and environmental importance, the emergence of birdwatching as a mass participation leisure activity in China over the past three decades is of global interest. We documented this emergence by conducting an extensive literature search and two online questionnaires which we used to describe the history, geographic distribution, demographics, activities, motivations, and environmental concerns of Chinese birdwatchers. The emergence happened because of (1) the transfer of ornithological knowledge to birdwatchers, (2) the increasing political tolerance to pursue pastimes, (3) the increasing leisure time, affordability of optical equipment, and urbanisation of China’s society, (4) increased internet use, and (5) interactions of birdwatchers with the media and foreign birdwatchers. Of the 576 respondents to our questionnaires, two-thirds were male, about half were younger than 35 years of age, approximately 90% were university-educated, and many also had an above-average income and originated mostly from the more urbanised coastal or near-coastal provinces. Our respondents were thus part of China’s economic and educational elite who largely birdwatch for enjoyment, but also because of the knowledge gained about the birds’ ecology. Many birdwatchers have become concerned about the deteriorating state of the environment and are frustrated about the lack of government action. Within the political constraints set by the government, many birdwatchers support environmental conservation through various activities, which have yielded some conservation successes. However, birdwatching societies remain constrained by the same legislative and administrative restraints which limit the actions of other environmental non-governmental organizations, thus hindering the effective discourse between China’s government and its emerging but still strictly controlled and regulated civil society.

Serra da Capivara National Park covers an area of about 1,300 km2 in south-eastern Piauí, north-eastern Brazil. The park's vegetation is the endemic caatinga, with a few remnants of semi-deciduous forest in some canyons. The area has a reasonable diversity of plants, with 615 catalogued species. Since 1986, 208 bird species have been observed in the park and its buffer zone, including 10 threatened or near-threatened species, plus two recently extinct in the area. Other species are regionally rare and have declined over parts of their distribution. The park also harbours several threatened mammals and caatinga endemics. Despite having been created in 1979 the park remains effectively unprotected and unmanaged. Current levels of poaching and habitat destruction prejudice the future of several species, including some that have already vanished from other parts of the caatinga.

O Parque Nacional da Serra da Capivara abrange uma área de aproxidamamente 1,300 km2 no sudeste do Piauí, nordeste do Brasil. A vegetação do parque é a caatinga, com alguns enclaves de mata semi-decíua. A área possui uma razoável diversidade de plantas, com um total de 615 espécies já catalogadas. Desde 1986, um total de 208 espécies de aves foram observadas no parque e sua zona-tampão, incluindo 10 consideradas ameaçadas ou quase-ameaçadas, além de duas recentemente extintas na área. Outras espécies são regionalmente raras ou tern declinado em parte de sua área de distribuição. O parque também abriga diversos mamíferos ameaçados, e endemismos da caatinga. Apesar de ter sido criado em 1979, o parque ainda não foi consolidado e é pouco mais que um parque de papel. Com os presentes niveis de caça clandestina e destruição de habitats, diversas espécies se extinguirão, incluindo algumas já desapareddas de outras partes da caatinga.

The distribution of Tahitian landbirds in the early twentieth century and at presented here together with maps. Three categories may be recognized: (1) species with a declining distribution owing to changes in habitats (Green-backed Heron), (2) stable or increased species, including local and earlier introduced species, and (3) newly introduced species (Zebra Dove, Red-vented Bulbul, Silvereye and Crimson-backed Tanager). Moreover, owing to their low population numbers, two species, the Pacific Pigeon and the Tahiti Monarch, are on the verge of extinction even if their distribution has not changed notably during this century.

Les repartitions des oiseaux terrestres reproducteurs de Tahiti, au début et à la fin du 20e siècle, sont présentées sous forme de cartes. Trois catégories d'espèces sont dis-tinguées: (1) espèce dont la répartition est en déclin a la suite des modifications d'habitats (Héron vert), (2) espèces stable ou en légère augmentation, chez qui on trouve des oiseaux locaux et des oiseaux introduits, et enfin (3) les espèces introduites durant le 20e siècle (Tourterelle striée, Bulbul à ventre rouge, Zosterops à poitrine grise et Tangara cramoisi). II apparaît que deux espèces, le Carpophage du Pacifique et le Monarque de Tahiti, sont aujourd'hui très menacées, même si leur répartition n'a pas régressé d'une façon significative.
