It is a migrant from tropical Africa and feeds mostly on caterpillars which are plentiful right now.
During breeding season it normally uses Weaver nests to play host to its eggs of which it lays one per season. This last picture is of an immature bird with a fat, juicy caterpillar in its mouth.
The second is Klaas’s Cuckoo which has only a small white stripe from the brown eye, backwards. It also has spots instead of bars on its chest.
It breeds in the northern part of South Africa and is a migrant in more southern parts. In size, it is much smaller than the Diederik Cuckoo and because of its shyness, is never seen.
The third was a female Cardinal Woodpecker which does not have the red stripe on the head like the male. I have always been envious of the lovely pictures I see posted of these great birds but never even get a glimpse of them here although they are very common birds and you hear hem calling all the time.
