Not sure if this is the best place to put this, but under conservation status on the Clark's Grebe page it says this
The Colima Warbler’s natural habitat ranges from the Sierra Madre
Occidental in central Mexico to the Chisos Mountains of the Big Bend
National Park in southwestern Texas. However, specimens were not found
outside of Mexico until 1928. This species nests on the ground, hiding
its young behind mountainous rocks. In the winter, the northernmost
populations will migrate short distances to the mountain ranges of
central and southwestern Mexico. The Colima Warbler prefers habitats
such as moist canyons and mixed hardwood and softwood forests. The
current conservation rating of this species is Near Threatened, as
populations have decreased in recent years.
Perhaps someone could fix this.
