Sightings |
An Upcher's Warbler was spotted by us on the campus of Sultan Qaboos University, near Muscat, in April 2010. In the same month a bird was spotted with a deformed bill; this bird was identified by an expert as an Upcher's Warbler (see below).

Bird with a deformed bill
While observed by us, the bird shown below was not obviously hampered by its misaligned mandibles, several insects falling victim to its snaps.

Slightly different posture, showing clearly the misaligned
mandibles; the lower mandible appears to be skewed sideways

Back of an Upcher's Warbler
While most of the time hunting insects in the top branches
of an acacia tree, the bird also occasionally went down to the
ground 
In between meals, there is time to preen; this posture shows
clearly the light colours of the undertail coverts

Food |
Like all warblers known to us, Upcher's Warblers feed on insects that they catch in flight or pick from foliage.
