Abstract
The present endeavor appraised the spatiotemporal relationships between saker falcon migration and environmental correlates at Jorbeer Conservation Reserve, Bikaner, Rajasthan, India during period from April 2015 to July 2016. Saker falcon (Falco cherrug) was observed only from November to March. Saker falcons were not evidenced during summer months (April, May, June and July) of years 2015 and 2016. The bird stayed at reserve during various months of the study when the temperature-humidity index (THI) values remained between 56.64 and 72.5. It was observed that maximum THI value threshold of saker falcon was 72.5. During the residential period of saker falcon, maximum environmental temperature varied between 21 and 350C. The date-wise observation of falcons including array and metric of comparisons i.e. per cent as well as the concurrent recording of environmental correlates can be used for monitoring falcon traffic in the conservation reserve that may have dramatic impacts to estimate migrant population. It can be deduced that falcons arrived and stayed when THI values were either 72.5 or less making the environment most suitable. The result of present endeavor exhibited precedent of wintering for saker falcons at the Jorbeer. It can be figured out that migratory raptors have savoir fare to toggle on various feeding strategies to façade threats of food dearth during months of year throughout migration. The endeavor will assist in comprehending the intricacies of environment and bird interactions during migratory drives.
