Миграция североазиатских воробьиных

Abstract

The East Asian-Australasian bird migration system is one of the most species-rich migration systems, nevertheless, we have very little information on the migration of the species that use the Asian-Australasian Flyway. Most knowledge is available about waterfowls (cranes, ducks). However, very little is known about songbirds, mainly due to the lack of large-scale, long-term ringing activities. Most of what we know about the migration of these species is based primarily on field observations and the results of the Migratory Animal Pathological Survey (MAPS) conducted in the 1960s and 1970s. In the 2010s, however, several local ringing projects started. They produced considerable knowledge about the migration of songbirds. More recently, geolocators have also aided researchers in their work, providing even more accurate data on the migratory routes and migratory habits of species. The present study summarises the data we have obtained over the past decade about the migration of long-distance migratory songbirds nesting in North Asia. The article is based primarily on the data collected at ringing stations in the Far Eastern Russia, complemented by research from other areas in East and Southeast Asia. This review highlights the need for further research to ensure long-term protection of species that, at times, show a drastic decline in numbers.
