Pygargue à tête blanche

The national bird of the United States and a symbol of American conservation success, bald eagles have a wingspan of up to 2.4 meters and inhabit forests and wetlands near open water across North America. Powerful aerial predators and scavengers, they specialize in fish but also take waterfowl and carrion. Nearly extinct by the 1960s due to DDT poisoning and hunting, the bald eagle recovered dramatically following pesticide bans and the Endangered Species Act.

Chevêchette du Colima

<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.
