About Leiothlypis crissalis (Salvin & Godman, 1889)
The Colima warbler (scientific name Leiothlypis crissalis (Salvin & Godman, 1889)) is a species of New World warbler. It is primarily found in the Sierra Madre Occidental and Sierra Madre Oriental mountain ranges of central Mexico. Its range only just extends into adjacent southwestern Texas, in the Chisos Mountains of Big Bend National Park. This warbler measures around 4.5 to 5 inches, or 11 to 13 cm, in length. Its base coloration is mainly dark gray and brownish, with a pale underside. The rump and feathers under the tail are yellow. It has a white eye ring, and a pale tint to its breast. Males have an orange spot on the top of the head. The Colima warbler closely resembles Virginia's warbler in overall appearance. However, Colima warblers are larger, more robust, and have heavier bills than Virginia's warblers. Virginia's warblers have much more yellow or pale color on their breasts, while the breast of the Colima warbler is grayer. For Virginia's warblers, the yellow coloration above and below the tail is greenish-yellow, while it is more orange-yellow in Colima warblers.
