Poyser Monographs: The Eagle Owl (Hardcover)

The Eagle Owl is one of the largest owls in the world, and is considered the most eclectic in terms of habitat, nest site and diet. An undisputed top predator, it can prey on a range of mammals up to the size of a fox, and almost every species of bird, reptile, amphibian and fish, as well as a wide spectrum of invertebrates. Surprisingly, this owl can breed almost anywhere, the female laying her eggs on a variety of natural and artificial structures over an array of altitudes. Despite being so adaptable, however, it is still a vulnerable species, and has suffered widely from persecution as well as other threats including electrocution on power lines, decreasing prey availability, the effects of pesticides and pollutants, and habitat alteration.

Vincenzo Penteriani and María del Mar Delgado have studied this fascinating bird extensively across its vast Eurasian range. In this book, they detail its intriguing ecology, covering distribution, foraging and breeding behavior, interspecific interactions, dispersal and conservation issues. The final two chapters provide a remarkable insight into vocal and visual communication. Scientists have long believed that owls and other crepuscular and nocturnal birds forgo the visual signals found in other avian species, but recent research on the Eagle Owl has suggested otherwise.

Bringing together more than 30 years of research, The Eagle Owl tells a story rich in detail of one of the most thrilling and magnificent birds in the world.
