Grey-capped Warbler (high altitude call)

> Hi Claudien
> Thanks for that interesting info about the Grey-capped Warbler call which
> seems well above altitudinal range ? not another bird possibly mimicking?
> Would definitely be worth following up ? did you get GPS co-ordinates on the
> spot where you heard it? I could then add this to the atlas as ?pending?
> till we can confirm. I?ve just been going through my records and the
> highest record I have of it is at 2531m on the slopes of Sabinyo.

> Neil ? what do your records say on altitude on the Grey-capped Warbler?

> Claudien, could you please let me get the co-ordinates on the Olive Thrush
> sighting as well ? would be good to see how much info we could get onto the
> atlas on this species. I see Neumann 1908 (as per Don Turner?s message)
> recorded Turdus olivaceus bambusicola commonly in the Hagenia belt between
> 3200-3400 but also had records up to 3800m on Karisimbi.

> Hi Marcell and All,

> Today, Faida and I while correcting data in the common bird monitoring

> Yesterday at the perimeter of the Volcanoes National Park I came across a
> very dark Olive Thrush with very little orange on the flanks and the bill a
> deep orange. The orange eye-ring was also quite prominent. This was at 2575m
> altitude. Interestingly almost identical in appearance to an Olive Thrush I
> had photographed earlier the year in Karen, Nairobi.

> A week ago, and only 500m south (2550m alt) from this point was an Olive
> Thrush with much lighter undersides and the lighter orange bill. The orange
> on the flanks were more extensive. This is also similar to the Olive Thrush
> regularly observed in Ruhengeri town and which I've photographed at my
> house. http://www.flickr. com/photos/ marcell_claassen /3707538326/

> Anybody have more info on these East African races of Olive Thrush and
> whether this is linked to altitudinal preferences in distribution?
