Dear all,
I had a careful listen and can confirm that O. garnetti calls are frequently heard at night from my house next to the Sigiria block of Karura forest. At times up to 5 or 6 different individuals can be heard from different nearby locations all calling very loudly indeed for a lot of the night. Some Galago like creatures with big eyes which could not be hyrax have been observed in a big mugumo tree just above the dining room veranda and at other places around the garden. It is not so easy for lay people to identify them when curled up among branches but the calls are unmistakable.
Cheers,
Chantal

    Hi Chantal,

    Yes, the loud calls of Otolemur garnettii and Galago senegalensis could hardly be more different.

    There is also a big difference in body size/weight. O. garnettii (ca. 800 g) is about 4X larger than G. senegalensis (ca. 200 g).

    Their movement through the trees/buses is also very different. O. garnettii moves relatively deliberately and slowly through the vegetation...whereas G. senegalensis frequently leaps (>3 m)...giving the impression that it is propelled by a large rubber band.

    When moving rapidly on the ground, both species hop bipedally...like a springhare or tiny kangaroo.

    Regards,

    Tom
