Description: The red warbler (Cardellina rubra) is a diminutive passerine bird belonging to the New World warbler family Parulidae, exclusively found in the highlands of Mexico, located north of the Isthmus of Tehuantepec. It shares a close relationship with the pink-headed warbler found in southern Mexico and Guatemala, forming a superspecies. This bird exhibits three ѕᴜЬѕрeсіeѕ, each inhabiting disjunct populations distinguished by variations in their ear patch color and the brightness and tone of their body plumage. Adults display a vibrant red plumage, complemented by either a white or gray ear patch, depending on the ѕᴜЬѕрeсіeѕ. Its wings and tail are ѕɩіɡһtɩу darker, edged in pinkish-red, while its legs are a dull red-brown.

Nesting: Breeding typically takes place between February and May, during which the female constructs a domed nest on the ground and lays three or four eggs. While she is responsible for incubating the eggs, both parents contribute to feeding the young and maintaining the nest. Fledging occurs within 10–11 days of hatching. Primarily insectivorous, the red warbler forages predominantly in understory shrubs, gleaning insects.
