An opportunity several days ago to hike Wanale mountain, the lovely backdrop to Mbale town, afforded some nifty sightings of birds taking advantage of the thermals rising at the cliffs' edge.
My favorite was an immature Ayre's hawk eagle (Hieraaetus ayresii) engaging in an impressive series of aerial maneouvres with three adult harrier hawks (Polyboroides typus).
There were also a dozen or so common (rock) kestrels (Falco tinnunculus) in evidence around the rock faces.
An interesting encounter was with a pair of white-necked ravens (Corvus albicollis) -- a common species in Malawi, but one that I have never come across in Uganda before. They were cruising along the edge of the mountain on the same thermal currents already mentioned. Since that day, I have seen this same pair (presumably) down in Mbale town scavenging refuse near a local hotel. I'll keep an eye out for them to figure out whether they're just passing through for a few days or weeks or intend to take up longer-term residence.
Speaking of ravens, one morning last week when I had observed the white-necked ravens near the hotel, I later visited Sipi Falls on Mt. Elgon and saw the fan-tailed ravens (Corvus rhipidurus) that are regular there. This was the first time that I can remember ever seeing two species of ravens in Africa in the same day.
One other raptor of special interest from the Wanale hike was a mountain buzzard (Buteo oreophilus) in flight, of which I had excellent views for ten minutes or more as we waited for others in the group to begin our descent.
