Peri saker called Storm by sarniebill1 on Flickr.Peregrine saker falcon. The peregrine x saker is an excellent hybrid and will chase gulls or other avian pests into cover wherever they may be. Two particular species of birds, peregrine and saker falcons, are widespread but heavily exploited birds of prey that exhibit migratory habit and are popular hunting falcons commonly found in the country. In particular, the saker is the national bird of United Arab Emirate. In the past century, the two falcons have been listed as endangered species with population decline, caused by a wide range of factors including migration obstacles, environmental changes, habitat loss, use of pesticides (e.g. DDT, PCBs), among others. In the late 1990s, the peregrine has been successfully removed from the endangered species list through the increased recovery efforts, but the saker is still facing this challenge.
