Contopus cooperi Nuttall, 1831

New records. One individual was perching on the treetop of a very conspicuous Eucalyptus sp. We recorded this species in systematic surveys on 4 April 2018.

Identification. Contuopus cooperi is the largest of the pewees, with heavy grayish markings on the sides as if the bird is wearing a waistcoat.

Remarks. We did not record any reproductive events. This species is a boreal migratory bird. It is threatened by logging and pollution from agricultural activities (Birdlife International 2017), as well as loss and alteration of its habitat (Altman 1997). The populations in and around Bogotá have been unchanged over the past 20 years ( Stiles et al. 2017).

Distribution. Canada to northern Bolivia and Brazil.
