Vultures are most natural scavengers and they provide an ecological, economical and cultural value. Their presence near the dead body at dumping yard in villages, cities and towns are natural habitat They are carrion feeder. The present note is case of leuclsm or partial albln丨sm in Long-b川ed vulture (Gyps indicus) in Udaipur district Rajasthan. We observed leucism has not affected adults activities like- matting, incubation of egg, nest reconstruction and foraging.
The bats Pteropus giganteus (Brunnich，1782) are confined to tropical countries like Bangladesh， Bhutan, India, China, Maldives, Myanmar, Nepal, Pakistan and Sri Lanka. Accordingly they are to face the severity of extreme heat during summer. But, to ensure their survival they have developed the art to combat the heat shock to overcome the effect of dehydration. In course of studies on R giganteus occurring at Simla (23^22’44.20″ N, 86^38’47.02″ E), Purulia of West Bengal, on the way of regular visit to the roosting site concerned it is revealed that, while atmospheric temperature exceeded 42-4^ C and the area was succumbed with loo, the bats were seen to (i) change their hanging posture by keeping the back portion of the body towards south and the front portion towards north, especially during 11.30 am to 3.30 pm; (ii) use their right wing as a fan to provide wind to the body through regular flapping; (iii) change the hanging posture little bit to ensure flapping of the wing by the fellow colony members; (iv) select the roosting tree very close to a waterbody; (v) dip belly at the surface water of the water body during afternoon, and licking water from the body surface following sheltering at the hanging site. Besides, they are also cautious in selecting the roosting trees having suitable canopy configuration so as to minimise the penetration of direct sunlight, at least to avoid the exposure of the direct sunlight It is to be mentioned here that during the years the atmospheric temperature some time raise up to 48^0. Thus, in several occasions many pregnant and aged individuals were seen dead lying on the ground beneath the roosting tree, perhaps being unable to overcome the heat-induced hazards. It is concluded that the bat population in tropical country are at the verge of extinction perhaps with the gradual rising of atmospheric temperature – the global warming.
