December 21, 2015 – Red Warbler (Cardellina rubra)
Requested by: @gepwin
These warblers are found only in three mountain ranges in Mexico, on the edges of pine-oak forests. Often foraging in pairs, they eat insects, picking them from surfaces or catching them in the air. Males become very territorial during the breeding season, singing and challenging rivals nearby. Females build cup or oven-shaped nests on the ground from grass, pine needles, and other plant materials, where they incubate three or four eggs.
