Grey-headed Fish Eagle
Icthyophaga ichthyaetus
The grey-headed fish eagle is a smallish to medium-sized but quite bulky fish eagle, with a small bill, a small head on long neck, rounded tail and shortish legs with unfeathered tarsi and long talons. Wings are not very long and wingtips reach less than halfway down tail. Males and females are sexually dimorphic. The grey-headed fish eagle has a body length of 61–75 cm (24–30 in). Females are heavier than males at 2.3–2.7 kg (5.1–6.0 lb) compared to 1.6 kg (3.5 lb). The tail measures between 23–28 cm (9.1–11.0 in) and the tarsus 8.5–10 cm (3.3–3.9 in). Voice: The calls of the grey-headed fish eagle include a gurgling awh-awhr and chee-warr repeated 5–6 times, an owlish ooo-wok, ooo-wok, ooo-wok, a nasally honking uh-wuk and a loud high pitched scream. These begin as subdued low short notes each succeeding one more strongly upturned and more strident then previous then dying away again and are uttered from a perch or on the wing.
