Phenology

First Brood

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).

The inner dimensions of one nest cup were 70 mm (diameter) x 45 mm (depth) (13).

Eggs
