In previous articles we’ve looked at the ability of large eagles – the Golden eagleAquila chrysaetos in particular – to kill surprisingly large prey. As in adult pronghorn, adult reindeer, juvenile red deer and juvenile domestic cattle etc. (see links below, or Cooper (1969), Deblinger & Alldredge (1996) and Nybakk et al. (1999)). Such behaviour isn’t unique to Golden eagles: Bald eagles Haliaeetus leucocephalus and other species can do similar things (McEneaney & Jenkins 1983). Eagles can be trained, of course, meaning that people can get them to do remarkable things that seem contrary to sensible behaviour: they can use them to hunt wolves, for example.
