The Red Warbler (*Cardellina rubra*) is an exceptionally striking and aptly named passerine, endemic to the highlands of Mexico. Measuring approximately 12.5-13.5 cm (5 inches) in length and weighing around 7.6-10 grams, this small warbler is almost entirely iridescent bright red, a truly arresting sight in the verdant Mexican forests.

This species primarily inhabits humid to semi-humid coniferous and pine-oak montane forests, favoring areas with dense understory. It is typically found at elevations ranging from 1,800 to 3,500 meters (5,900 to 11,500 feet).
The Red Warbler is primarily insectivorous, feeding on a variety of insects such as caterpillars, beetles, flies, and insect larvae, as well as spiders. It forages mostly by gleaning prey from foliage and branches, and occasionally by short aerial sallies.
