BIRDS
Birds (class Aves or clade Avialae) are feathered, winged, two-legged, warm-blooded, egg-laying vertebrates.
Modern birds are characterised by feathers, a beak with no teeth, the laying of hard-shelled eggs, a high metabolic rate, a four-chambered heart, and a lightweight but strong skeleton.

Photographer - Chris Brown While searching for food, coal tit flocks keep contact with incessant short dee or see-see calls. The species' song – if "song" it can be called – is a strident if-he, if-he, if-he, heard most frequently from January to June, but also in autumn. One variant of this song ends with a sharp ichi. North African birds also have a currr call similar to that of the European crested tit (Lophophanes cristatus) which is not found in Africa.

Photographer - Chris Brown The great tit is a distinctive bird, with a black head and neck, prominent white cheeks, olive upperparts and yellow underparts, with some variation amongst the numerous subspecies. It is predominantly insectivorous in the summer, but will consume a wider range of food items in the winter months, including small hibernating bats.

Photographer - Chris Brown The river kingfisher hunts from a perch 1–2 m (3–6 ft) above the water, on a branch, post or riverbank, bill pointing down as it searches for prey. It bobs its head when food is detected to gauge the distance, and plunges steeply down to seize its prey usually no deeper than 25 cm (10 in) below the surface. The wings are opened under water and the open eyes are protected by the transparent third eyelid.
