Square-tailed Nightjar

It's C. fossii. C. clarus is not living around L. Malawi.

From a single photograph, I am 99% sure the ID is correct. I've seen them myself in Kenya.

How sure are you about the ID? I have to say that those nightjars are the easiest birds I got in Tanzania. Take a red torch and walk along the beach at night. The eyes are glowing red. And the birds do not fly away. Pic was taken with a macro lens.

Welcome to Project Noah, excellent spotting! Hard to spot I bet

Oh, and this is your first spotting on Project Noah too. Welcome to you :-)

An excellent spotting. These aren't the easiest birds to spot, particularly at night. Their 'sit still and be quiet' defense can also be their undoing. I'm sure many are killed by being driven over or trodden on.

Beautiful!
