Around the famous sinkhole, Yemen serin can be seen although I have failed to see them yet. The cooler months of December and January are the best for that when they spend more time out of their cold environment down the hole. An early morning visit might do it too.
Nevertheless I spend an hour around the top searching for them. Ironically it was here where I came across a male Palestine sunbird which was a target bird in the morning.

I got prolonged views of this bird too. When sunbirds are feeding they are easy to view. Otherwise they are near impossible.
Around the sinkhole were many birds. Tristram's starling, cinnamon-breasted bunting, Abyssinian white-eye and Eurasian collared dove are all common. Plenty of pale crag martin were flying over the top too.
There is much more to the Tawi Atair area than the sinkhole. This is farming country with many cattle. The farmhouses in particular attract birds.
