Three individuals flying over PJDNR on
12 June 2016
.

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
