PHENOLOGY OF SPRING MIGRATION OF BIRDS IN THE SOUTHERN BAIKAL AREA IN 2020
Dates of the first arrival were analyzed for more than 150 bird species in the unusually warm spring 2020. For 20 species first records were earlier than the earliest arrivals in 2006-2014; among ones, Black Stork, Peregrine Falcon, Demoiselle Crane, Longtoed Stint, Sand Martin, White’s Thrush, and Brambling arrived for 10-20 days earlier than it had taken place in the period of years mentioned above. Seven species have arrived later than the latest arrival dates of the same period. Twenty species didn’t show any declination from average arrival dates. For others the information is insufficient and first coming birds can be overlooked.
