In view of its wide distribution and relative abundance, there is remarkably little information regarding the breeding biology of Crimson-collared Tanager.
Breeding has been reported from Belize in May (16), from March through May in Nicaragua (13), in early April in Honduras (10), and from April through June in Costa Rica (9). A female collected in July in Chiapas, Mexico, had enlarged ova, suggestive of breeding activity (37).
Structure and Composition
The inner dimensions of one nest cup were 70 mm (diameter) x 45 mm (depth) (13).
The dimensions of one egg were 24.2 mm x 16.4 mm (13).
Color and Surface Texture
No information but adults have been documented feeding juveniles (see below).
