Severe Winter Temperatures Impact Bird Count in Odesa Region.

Bird Population Survey in Odesa Region Shows Impact of Harsh Winter

According to Novyny.live: A mid-winter bird count on the wetlands of the Odesa region has revealed significant changes in both the numbers and species of birds present, a shift attributed to severe weather conditions. Temperatures in the region plunged to -12 °C, substantially affecting the wintering patterns of the avian population. This area is a crucial stopover point for many migratory species traveling along the Black Sea-Mediterranean flyway.

Findings from the Bird Count

The survey was conducted from January 19 to 22 across the 'Shagany — Alibey — Burnas' lake system. Ecologists recorded over 20,000 birds representing 47 different species. The most numerous species was the mallard duck, with a count exceeding 7,500 individuals. The survey also documented:

• Approximately 7,000 white-fronted geese;
• 2,600 Eurasian wigeons;
• 1,300 shelducks.

Among other notable sightings, three species of swans were present, though their numbers remained small—only a few dozen of each. The presence of 140 yellow-legged gulls was also noted. Furthermore, a number of common cranes were observed, having remained in the region for the winter instead of migrating further south.

Consequently, this bird count, carried out during a period of intense cold, proved vital for understanding shifts in wintering behavior and population dynamics. Monitoring bird behavior during extreme weather events is critical for assessing the health of the regional ecosystem. Changes in species composition and numbers can indicate the adaptive mechanisms birds employ to survive in an increasingly unstable climate, and such surveys help scientists track population trends and refine conservation strategies.
