Description of the Nest and Parental Care of Euphonia chlorotica (Birds: Fringillidae) in Santa Cruz, Bolivia

Abstract

This study describes the first data on reproductive aspects of Euphonia chlorotica in Bolivia by monitoring a nest built in a hanging planter inside a house located in Santa Cruz de la Sierra. The nest was globular in shape with a lateral entrance typical of the species and was built within 6 days in December 2019. Three whitish eggs with dark brown spots were incubated for 16 days exclusively by the female. The nestlings hatched synchronously on January 25, 2020 and after 16 days they left the nest with their plumage fully developed, except for the length of the tail feathers, and with the beaks still with the characteristic yellow commissure of the juvenile. The feeding of the nestlings was carried out by both parents and the probability of daily nest survival and nesting success was 100% despite being in a highly urbanized environment.
