The reed beds of the Esplanade wetland with stands of bulrush, sedges and horsetails is a bird canteen and home. Warm and shallow water and leeward create good conditions for the development of various insects, such as mayflies, caddisflies and others, with which birds feed during the day, and bats at night. Insects and their larvae also make up a significant part of the food of the black-headed gull, which is the loudest and most noticeable bird species here in spring and early summer. Some songbirds, such as warblers, live directly in the reed bed and occur outside them only during migration. Do you know how many thousands of black-headed gull pairs have been in the largest black-headed gull colonies in Latvia and why they disappeared?
