⭐ Core Definition: Grey heron

The grey heron (Ardea cinerea) is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.

Standing up to 1 metre (3 ft 3 in) tall, adults weigh from 1 to 2 kg (2 to 4 lb). They have a white head and neck with a broad black stripe that extends from the eye to the black crest. The body and wings are grey above and the underparts are greyish-white, with some black on the flanks. The long, sharply pointed beak is pinkish-yellow and the legs are brown.

👉 Grey heron in the context of Rostrum (anatomy)

Grey heron in the context of Kwara State

Kwara (Yoruba: Ìpínlẹ̀ Kwárà) is a state in Western Nigeria, bordered to the east by Kogi State, to the north by Niger State, and to the south by Ekiti, Osun, and Oyo states, while its western border makes up part of the international border with Benin. Its capital is the city of Ilorin and the state has 16 local government areas.

Of the 36 states of Nigeria, Kwara is the ninth largest in area but the sixth least populous with an estimated population of about 3.2 million as of 2016. Geographically, Kwara is split between the West Sudanian savanna in the east and the Guinean forest–savanna mosaic ecoregion in the rest of the state. Important geographic features include rivers with the Niger flowing along the northern border into Lake Jeba before continuing as the border while the Awun, Asa, Aluko, and Oyun rivers flow through the interior. In the far northwest of the state is the Borgu section of the Kainji National Park, a large national park that contains populations of grey heron, kob, hippopotamus, African bush elephant, olive baboon, and roan antelope, along with some of the last remaining West African lions on earth. In the far southwest, a small part of the Old Oyo National Park contains crowned eagle, martial eagle, African buffalo, oribi, and patas monkey populations.
