American kestrel population trends and vital rates at the continental scale
Ecosphere, Volume 17, Issue 2, February 2026.Abstract The American kestrel (Falco sparverius, hereafter referred to as kestrel) has declined across much of its North American range since at least the mid‐1960s. Kestrel population dynamics have been explored through a multitude of local studies and two broad reviews of available data. Across large geographic extents, however, the demographic cause(

Wildlife Biology, Volume 2026, Issue 1, January 2026.During the 18th and 19th centuries, bird feathers (class: Aves) were harvested from wild populations and sold globally in enormous quantities to meet the rising demand of the fashion industry. Although many laws now prevent similar widescale harvest, there is a paucity of studies on the trade that has continued to occur since the 20th century.
