The left upper image of a Verreaux's eagle, also called the black eagle, was taken at Naisera in March 2007. The middle images were taken at Lobo in November 2008, courtesy of Henrik Kisbye: note the curved wing shape and the huge white "windows" on the primaries which seem to continue to some of the secondaries. The other images were taken at Soitorgoss in March 2009. The video of a bird in flight nicely shows the underwing too, click link to right.
