New records. Several adults and chicks have been heard and seen, hiding in the grasslands of the ESNR. We recorded this species in systematic surveys in all the samples since the beginning of our study.

Identification. Adults with a sturdy body, long pointed beak, long legs, and short tail; head with broad blackish and whitish brown lists; the dorsal region is dark-brown, barred with black; throat, chest, and belly bright yellow with a black V-shaped spot; ventral region dark, mottled brown in young birds.

Remarks. On 10 July 2018, we observed a nest with three chicks devoid of feathers and down and with closed eyes. On 31 October 2018, we recorded a nest with three eggs (27.74 mm × 20.11 mm). The species is threatened by ag- ricultural activities (use of pesticides and herbicides) and livestock. However, the population trend is currently increasing (Birdlife International 2018). In Bogotá and its surroundings, populations have been undergoing a reduction in their abundance as a result of the loss of grasslands for housing and exotic flower crops ( Stiles et al. 2017). As part of the conservation strategy for this species, grassland areas without contaminants where the species can nest can be increased ( Jaster et al. 2012).

Distribution. North and Central America and northeastern South America.
