Caspian gull

The Caspian gull, scientifically referred to as Larus cachinnans, is a sizable gull belonging to the same family as the herring and lesser black-backed gulls. This bird is distinguishable by its significant size and unique characteristics, such as a long, slender bill, and relatively longer legs, wings, and neck compared to other gull species. These gulls inhabit regions around the Black and Caspian Seas, extending into Central Asia, China, and parts of Europe.

During the breeding season, which begins in early April, Caspian gulls typically nest on flat, low-lying ground near water bodies. They generally lay two to three eggs, which they incubate for approximately 27 to 31 days. As scavengers, these gulls have a diverse diet.

The classification of the Caspian gull has undergone revisions over time. Some ornithologists now recognize it as a distinct species rather than merely a subspecies of the herring gull. There are also related subspecies, such as the steppe gull (Larus fuscus barabensis) and the Mongolian gull (Larus mongolicus), each exhibiting unique breeding and migratory behaviors.
