Crested Lark

A medium-sized lark named for its distinctive long, pointed crest, crested larks inhabit dry, open country, agricultural land, roadsides, and desert margins across Europe, North Africa, and Asia east to China. They are ground-dwellers rarely perching in trees, walking confidently with the crest raised. Less migratory than most larks, many populations are resident year-round. They produce a rich, melodious song from ground-level and low perches. Populations in Western Europe are declining due to agricultural changes.
