Buteo platypterus Vieillot, 1823 Figure 7B, C New records. About 1,500 individuals were recorded in a boreal migration flying above the ESNR and PJDNR on 7 April 2018. The flock included Buteo platypterus and B. swainsoni Bonaparte, 1838. We recorded this species in systematic surveys in November of each year. Identification. Adult and immature individuals show differences in plumage. Adults have dark brown on the dorsum and barred chest. Immatures are similar on dorsum, but the chest is whitish with brown stripes. Remarks. We did not record any reproductive events. This species is a boreal migratory bird. Distribution. USA, Canada, Mexico, Central America, northwestern South America to western Ecuador, Bolivia, and northwestern Brazil. Elanoides forficatus Linnaeus, 1758 New records. Three individuals flying over PJDNR on 12 June 2016. Identification. The body is a contrast between deep black and white. The flight feathers, tail feet and bill are black. The tail is elongated and forked. Remarks. We did not record any reproductive events. This species is a boreal migratory bird. We consider this species as an isolated record due to its unique record of three individuals. They could be wandering individuals of the subspecies Elanoides forficatus yetapa (Vieillot, 1818 ) resident in Colombia (Ayerbe-Quiñones 2018), being recorded at a time when the migration of birds from the north of the continent was not usual.
