(I should just point out that the leg and cere coloration could differ from orange to yellow to red)
How to id an accipiter.
The following birds can be found in this group:
Again as with eagles a rule of 4 is the trick to id these species:
first of all, from a front on view this genus can be distinguished from the similar and somewhat larger
sized Melierax(Gabar, Southern Pale and Dark Chanting Goshawks) genus and the Lizzard Buzzard
by the lack of two toned underparts on the throat and breast.
the Cere plays a bigger role in these species.
1. This bird has an orange/yellow cere(which also could be yellow at times in the case of Ovambo Sparrowhawk). This excludes African Goshawk and adult Black Sparrowhawk.
2. The eye. Dark brown with a hint of red. This will exclude just about every other bird of this genus.
Out goes the Little Sparrowhawk(yellow ring around eye), the Shikra(bright red eye, but shade could make it seem dark),
Rufous-Chested Sparrowhawk(yellow eye), Black Sparrowhawk(apart from the distinct black coloring in the adult,
the eye is also red, but shade could make it seem dark) and African Goshawk(Yellow eye).
(At this point you can actually id it as the Ovambo Sparrowhawk.)
3. The throat and breast pattern and color. This bird is finely barred from throat to tail.
This will exclude Black Sparrowhawk, Rufous-Chested Sparrowhawk, Little Sparrowhawk and Shikra
(all 4 have a white throat)
4. The tail. From the back this bird's tail has a unique pattern. It has a barred upper tail with 3 white distinctive
central spots on each dark bar. The Little Sparrowhawk has 2 white tail spots on the upper tail.
The Shikra has an all grey plain upper tail.
On conclusion one can see that this bird is an Ovambo Sparrowhawk.
