Colima Warbler

<em>Leiothlypis crissalis</em>, the Colima Warbler, is a wood warbler in the family Parulidae. This species is assessed as Least Concern on the IUCN Red List. It breeds primarily in the Chisos Mountains of southwestern Texas in the United States and adjacent areas of northeastern Mexico, where it inhabits oak, juniper, and pine-oak woodland at higher elevations. <em>Leiothlypis crissalis</em> is a migratory species that winters in Mexico. The genus <em>Leiothlypis</em> was separated from <em>Vermivora</em> following phylogenetic revisions in the early twenty-first century. Colima Warblers typically forage in shrub and tree understories, gleaning insects and other invertebrates from vegetation. Diet, population estimates, and biological measurements such as average length, weight, and lifespan are not specified in available records. No specific country occurrence records are listed in the available data for this species. Its Least Concern designation reflects that current population levels do not indicate an elevated extinction risk, though the species' restricted breeding range in a single mountain range makes it of conservation interest.
