Lucy’s Warbler Resting on Mesquite Branch in Arizona - Foto stock

Lucy’s Warbler (Leiothlypis luciae) perched quietly on a mesquite branch in Arizona. This tiny gray warbler is one of the smallest North American wood-warblers, often recognized by its subtle rufous crown and rump, which are sometimes hidden from view. Active among desert trees, it forages for insects and nests in natural cavities or bark crevices. Protecting mesquite bosques and desert riparian corridors is essential for the conservation of Lucy’s Warblers and for maintaining the delicate balance of desert ecosystems threatened by habitat loss and climate change.
