New records. Several individuals flying around the wet- land vocalizing around the wetlands of the ESNR on 27 June 2016. Since then, we have recorded this species

systematically in over 80% of the samples.

Identification. Adult males with black body and yellow hood with black flanges; conical peak; female with brown olive dorsal region with diffuse brown striatum; super- ciliary and yellow throat, with facial area and opaque yellow crown, rest of the olive yellow body; young ones similar to females but paler tending to whitish.

Remarks. On 16 June 2018, we observed a couple feeding a young individual of Molothrus bonariensis Gmelin, 1789 . On 08 April 2019. we recorded two cup-shaped nests with light blue eggs (22.8 mm × 16.9 mm) with some dark spots in its widest part. The population has been increasing since 2017 after the restoration actions carried out in the wetlands.

Distribution. Colombia to northern Brazil and northeastern Peru.
