Review of Spring Migration

Finally, we finished the review of 2015 spring migration!

Approximately 220,000 individuals from 32 species were recorded during the observation between 10 March and 20 May in Istanbul. According  to known studies about spring migration that is observed from single point, recording the highest number makes this study important. The reason why the highest number is recorded this year is probably because the commanding place(ancient  castle remains) in the same area is used in this study.

Goc (2075)Black Stork

If we evaluate the differences from other studies on the basis of species;

The numbers of White Stork, Osprey, Greater Spotted Eagle, Steppe Eagle, Lesser Spotted Eagle, Pallid Harrier, Levant Sparrowhaw, Kestrel and Hobby are highest than previous years.

The numbers of White Pelican, Egyptian Vulture, Imperial Eagle, Hen Harrier, Sparrowhawk, Black Kite and Red-footed Falcon are less than previous years.

The differences in the number could be caused by gale force,  windward, number of observation days and the point.
