CONSERVATION STATUS

Near Threatened

The Colima Warbler breeds in pinyon-juniper and pine-oak woodlands between elevations of 3,000 feet and 9,000 feet. This species breeds in the Big Bend area of western Texas south to San Luis Potosi, Mexico, and winters in the understory of semi-humid and humid montane forest in west-central Mexico. It forages for insects and small larvae in lower levels of woodland habitats. Although the size of the global population is unknown and believed to be decreasing on account of habitat loss in Mexico, it is still considered large enough to warrant a conservation rating of Least Concern.

INTERESTING FACTS

  • The Colima Warbler was thought to be restricted to Mexico until a specimen was collected in Texas in 1928. It was later confirmed that the warbler breeds in Texas. It is unclear if this represents a range expansion or was simply overlooked until then.
  • They have been observed adapting to weather patterns. In 1996, a snow and ice storm arrived after the Colimas returned to breeding territories and destroyed much of their food supply. The Colimas relocated to lower-elevation sites for breeding that year.
  • A group of warblers has many collective nouns, including a "bouquet", "confusion", "fall", and "wrench" of warblers.
