with in Madagascar. It can be told from all other South African 
Hawks by its thin, weak bill, with the feathers of the lores covering 
half of the nostril. It has also a well-marked occipital crest. 
Mr. Andersson gives the following note :—‘‘ On the 10th March, 1865, 
I obtained one specimen, a female, of this singular bird at Otjim- 
binque, Damara Land; it was shot by my servant, who observed 
another, probably the male. I imagine that I have myself 
observed it once or twice in the neighbourhood of Otjimbinque 
just before dusk. When brought to me I instinctively suspected 
the bird to be a feeder at dusk or at night, and called out, ‘Why, 
that fellow is likely to feed on bats!’ And truly enough, so 
it turned out; for, on dissection, an undigested bat was found 
in the stomach ; and in another specimen, subsequently killed by 
Axel, there were several bats in the stomach.” 
The accompanying description is taken from the ‘“‘ Catalogue of Birds.”
