These conditions resulted in many migrants (including red footed falcons , red throated pipits and grey-headed wagtails) all travelling far to the west of normal routes from Africa to northern breeding grounds.
American kestrels, smallest of North America's falcons , migrate at about the same time as the jays and flickers.

The Royal Society for the Protection of Birds estimates that around 100 birds of prey, including eagles, falcons and hen harriers, are either poisoned, shot, trapped or have their nests destroyed every year on the Scottish moors.
Tens of thousands of hawks, kites, falcons , eagles, osprey, vultures, and harriers appear in the skies over the Golden Gate from August through December.
Accipiters have rounded wings, whereas falcons have pointed ones.
They're subject to a lot of pressures from predators, aerial predators such as falcons , sea eagles, and they need to have a clear line of sight to an area of escape for them, and also so they can see predators in advance.
And of course, today we have such adept flyers as the swallows, hummingbirds, falcons , and the soaring albatrosses which demonstrate the great diversity of flight adaptations in birds.
