コリマスズメフクロウ
<em>Glaucidium palmarum</em>, the Colima Pygmy Owl, is a small owl in the family Strigidae. This species is assessed as Least Concern on the IUCN Red List. It is endemic to Mexico, found along the Pacific slope in the states of Jalisco, Colima, Michoacán, and Guerrero, where it inhabits tropical dry forests and adjacent woodland edges. Members of the genus <em>Glaucidium</em> are among the smallest owls in the world and are known to be aggressive hunters relative to their size, often preying on insects, lizards, small birds, and rodents. <em>Glaucidium palmarum</em> is typically active during the day and at dusk. Diet information, population estimates, and biological measurements including average length, weight, and lifespan are not specified in the available data for this species. Its Least Concern status indicates that the population is not currently considered at elevated risk, though continued monitoring is advisable given ongoing pressures on tropical dry forest habitats in Mexico. The Colima Pygmy Owl occupies a range of aerial, terrestrial, and aquatic environments associated with its forest habitat.
