Resumen

A single nest of the Golden-rumped Euphonia (Euphonia cyanocephala) was filmed for 72 hours near the Yanayacu Biological Station in Ecuador located in tropical montane forest. Recording was between 15-21 February 2014. We report the first observations of incubation and feeding behavior by individual parents. We use the collected observations collected during the six day period after hatching to analyze visit frequency, duration, time, and activity patterns during visits. Both male and female visited at similar rates (mean male = 20.2 ± 1.8, mean female = 21.0 ± 1.3 visits/day) with an alternation of visits by members of the pair the typical pattern. Only the female was observed brooding and both sexes were observed feeding two nestlings. Males were documented performing flybys, although limited observations suggest females may also display a variation of this behavior. One member of the pair would often act as a sentinel while the other was visiting the nest. Behaviors observed were consistent with other members of the Euphonia.
