MORE FOR THE OLIVE/MOUNTAIN THRUSH COLLECTION.




Dear Neil and Liz,

Here are some more thrushes for the fast growing collection.

Listen to the sounds from Uluguru, by Brian Finch

1. ROEHLI from the Magamba Sawmill Road, West Usambaras.

2. Now this bird is an OLDEANI from Sopa Lodge, Ngorongoro. If you
read the description of Oldeani from the Handbook, you will find that
it has little in common with this bird. Either Oldeani is a suspect
race, or birds on the Crater Rim are not oldeani.

3. This is a nominate from 10,000 feet on Mt Kenya in the bamboo zone.
Not a great difference between this and the bird from the Crater Rim.

4. This is the form around Nairobi, it is richer than the Mt Kenya
birds though they are the same race.

5. These are three different calls from the bird on the Ulugurus,
treated in the Handbook as Nyikae. The bird was almost black head to
chest, hardly any relief on the throat. Dark below but somewhat
browner. In flight the rusty flanks were very conspicuous on the
almost uniformly dark bird. I can find no illustrations or images of
nyikae. Whilst roehli is dark, “nyikae” on Uluguru appears as black as
helleri from Taita Hills. I hope that someone can find a use for this.
As you can hear it is very strong and melodic.

Best for now
Brian
