The Cuban Sandhill Crane Grus canadensis nesiotes and Cuban Parrot Amazona leucocephala palmarum are considered endangered species in Cuba and the Isla de la Juventud (formerly Isla de Pinos). Coincident with a public education campaign, a population survey for these species was conducted in the northern part of the Isla de la Juventud on 17 December 1995, from o6hoo to 10hoo. Residents from throughout the island participated, manning 98 stations, with 1–4 observers per station. Parrots were observed at 60 (61.2%) of the stations with a total of 1320, maximum (without correction for duplicate observations), and 1100, minimum (corrected), individuals counted. Sandhill cranes were sighted at 38 (38.8%) of the stations, with a total of 115 individuals. Cranes and parrots co-occurred at 20 (20.4%) of the stations.

Resúmen

La grulla Grus canadensis nesiotes y la cotorra Amazona leucocephala palmarum son dos especies de aves cubanas amenazadas de extinción que ocurren en la parte Norte de la Isla de la Juventud, Cuba. Para ambas especies se organizó un conteo poblacional, donde de forma masiva participó toda la población de la Isla. El conteo se llevó a cabo de día 17 de diciembre de 1995, en 98 puntos de observación (PO), dispersos por todo el Norte de la Isla, entre las o6hoo y 10hoo, con 1 a 4 observadores por punto. En 60 PO (61.2%) se observaron cotorras, dando un total de 1320 individuos (sin corregir par posibles observaciones repetidas) y 1100 (corregido). En 38 PO (38.8%) se detectaron grullas, dando un total de 115 individuos. Grullas y cotorras coocurrieron en el 20.4% de los PO en los Indios.
