This video is about raptor migration in Panama.
The Dutch SOVON ornithologists report about migration of birds of prey.
Yesterday, 27 August 2017, was a good day for raptor migration.
451 honey buzzards were counted. And 278 marsh harriers; though most individuals of this species migrate in September.
There were 38 ospreys. And four Montagu’s harriers; one hen harrier, and a pallid harrier (claimed; experts still have to find out whether it was really that rare species).
