Watched a parasitic jaeger in Harney County this fall. Perfect conditions for soaring here, but this one put on a superb display of aerobatic falcon like skills forcing gulls to drop food. (And minutes later we saw a peregrine and prairie falcon hunting the same area).
Reminded us of frigate birds tipping red footed boobies returning with food to feed chicks on the nest, when we worked at French Frigate shoals 500 mi N of HI.
A rare site in Harney County !
