From Common Kestrel
It breeds in colonies under the roof tiles of churches and castles, and eats insects.
From Lesser Kestrel
It breeds in colonies in town centres and historic buildings, one of the few raptors that depends directly on human structures to nest.
From Lesser Kestrel
It breeds inside villages: under the roof tiles of churches, castles and farmsteads in Extremadura, Andalusia and Castile, which is why its conservation depends as much on farming as on how historic buildings are restored.
From Lesser Kestrel
It can see rodent urine: the urine of voles and mice reflects ultraviolet light, which the kestrel perceives, so it picks out the busiest trails from the air as though they were marked roads.
From American Kestrel
Its decline in North America is an open mystery: the population has fallen by more than half since 1970 without a single cause being identified, and everything from insecticides to the loss of nest cavities is under investigation.
