Spatial restriction and low cage height can reduce the rate at which comfort activities, such as wing flaps, stretching, body shakes and tail wags, are carried out by laying hens in conventional wire cages. In this study we investigated the performance of these activities in laying hens housed in furnished cages with perches and nest boxes, similar to those required in EU legislation from 2012. We compared the behaviour of groups of eight hens at a stocking density of 762 cm2 per bird with that of pairs of hens housed at a lower stocking density of 3048 cm2 per bird at two minimum cage heights of 38 cm and 45 cm. The rates of wing/leg stretches (0.80 stretches per hen per hour), tail wagging (0.76), body shaking (0.48), wing raising (0.19) and feather raising (0.05) were low, whilst full wing flaps were not observed during the study. Hourly rates of performance of wing/leg stretches (0.45 vs 1.06) and tail wags (0.34 vs 1.25) were significantly lower in eight-bird cages than in two-bird cages. We conclude that reducing the number of hens in furnished cages increases opportunities to perform certain comfort activities, but that, even at low stocking densities, comfort activities are rarely observed.

The purpose of this study was to investigate the behavioural effects of keeping circus elephants in paddocks. Therefore some species-typical behavioural characters and the occurrence of stereotyped movements were observed and compared in unshackled paddock keeping versus shackled keeping. The investigation includes 29 elephants (19 Elephas maximus, 10 Loxodonta africana) at four circuses located in Germany and in Switzerland.

The results showed that paddocks offered more freedom for comfort, social and play behaviour since such activities were observed more frequently in paddocks than in shackled keeping. Also, stereotyped movements were nearly absent in paddocks and very frequent in shackled keeping. In comparison to shackled keeping, paddocks were more suitable for the needs of elephants.

The predaceous fish barracuda (Sphyraena barracuda) is recorded rubbing itself against the carapace of moving hawksbill (Eretmochelys imbricata) and green turtles (Chelonia mydas) at Fernando de Noronha Archipelago, off north-eastern Brazil. To scrape against such a rough surface is probably employed by the fish to get rid of external parasites.
