8-10-2017 PEGO MARJAL, ALICANTE - BOOTED EAGLE (Hieraaetus pennatus)

The booted eagle, Hieraaetus pennatus, is a medium-sized bird of prey, with a stature comparable to the common buzzard. It exhibits sexual dimorphism, with females being larger, weighing approximately 840–1,025 grams, while males are lighter at 510–770 grams. The species measures around 40 cm in length and boasts a wingspan ranging from 110 to 132 cm. It is characterized by two distinct plumage morphs: a pale variant with light grey feathers and a darker head and flight feathers, and a darker morph with mid-brown plumage and dark grey flight feathers.

When identifying the booted eagle, look for the white markings on the wings, often referred to as "landing lights," which are visible when the bird is in flight. The pale morph is dominant, but the darker morph can be more prevalent in certain eastern populations. The call of the booted eagle is a distinctive shrill "kli-kli-kli."

The booted eagle favors wooded, often hilly landscapes with some open areas. It breeds in rocky, broken terrain but is adaptable during migration, utilizing a variety of habitats except dense forests.

This raptor has a wide distribution, breeding in southern Europe, North Africa, and across Asia, with a disjunct breeding population in southwestern Africa. Northern populations are migratory, wintering in Sub-Saharan Africa and South Asia, while the southern African populations are sedentary.
