The 'Piapiac' (''Ptilostomus afer'') is a member of the crow family, and is the only member of the genus ''Ptilostomus''. According to recent findings, it is most closely related to the
Central Asian
ground jays (Ericson ''et al.'', 2005).
In size it is a little smaller and slimmer than the
European Magpie (''Pica pica'') though the bill is relatively thicker. The overall colouring of the
bird is black with the feathers quite silky in texture and having a purplish gloss in good light. The base of the tail tends to be more brown in colour than the rest of the body. The nasal plumes are somewhat upturned on top of the bill but fully cover the nostrils. The bill itself is black in the adult but partly reddish-pink towards the base in juvenile specimens. Legs and feet are black. Iris is variable but tends towards violet, purple or mauve with a bluish-purple outer ring.

Distribution map
The range of the species is the
tropical equatorial region of central
Africa from
Senegal on the west coast, eastwards in a broad band to
Sudan and southern
Ethiopia. Within this range, its favoured habitat is towards more open country of cultivated land with fields and pasture and small associated towns and villages.
Food is obtained in flocks of ten or more birds moving together on the ground including
insects and other
invertebrates but will take a degree of carrion, possibly attracted as much by the associated insects this attracts as much as the meat itself. Some fruit is also taken in trees with the oily fruit of the
Oil Palm ''Elaeis guineensis'' a favourite. Able to run fast with some agility, it tends to hop at slower speed and will catch insects disturbed by the feet of cattle, sometimes hitching a ride on their backs and darting out to catch the prey.
Nesting is quite often in a palm tree, though other types are used also. Strips of palm leaf and
grass stems are cemented together with mud and lined with palm fibre to form a cup. Three to seven eggs are laid and are very pale blue or greenish-blue with a few brown blotches from March to April.
The voice is usually described as a shrill squeaking often with the
Jackdaw-like overtones. There is also a croaking alarm call given in anger where the head bobs.
