Last Sunday, with Nigel Hunter and Brian Finch we observed this loringi form of the Red-faced Crombec along the Mbagathi in Nairobi National Park. 

I made the attached photo. 

It would be interesting to hear what forms of the species you're observing around your area. Colin Jackson's record from the coast was an interesting form minima.

Keen to see more records.

Please remember to share records on Kenya Bird Map too.
