Bulletin 371 - Uganda #15 - Hornbills and 3 monkeys

After the week in the Capetown area, the guide Casper Badenhorst, and I flew to Uganda and met a local guide. We started at Entebbe Airport on the southeast corner of Uganda and made a diagonal trip to Murchison Falls NP in the northwest corner. From there, we proceeded south through a chain of nature preserves and parks to the southwest corner at Bwindi Impenetrable Forest. We finished along the southern border back to the airport.

There are 2 species of ground hornbills. I saw the Southern Ground Hornbill in Kruger Park on my first Africa trip. Here is the other - the 36" Abyssinian Ground Hornbill (Bucorvus abyssinicus). It is a large black hornbill found walking along the ground searching for insects, snakes, lizards etc. It is an easy ID and the huge size cannot be confused with any other bird. This is a male with the blue around the eye and red throat patch

There are 59 species of hornbills with 27 in Africa and the rest in Asia. The 29" Black-and-white Casqued Hornbill (Bycanistes subcylindricus) has a huge bill with a casque protuberance on top. It has a black body, white belly and tail, and primaries on wings.

Very similar is the 28" White-thighed Hornbill (Bycanistes cylindricus). The only obvious difference is the white ring around the eye and the tail has a black stripe across the middle.

The 22" Crowned Hornbill (Tockus alboterminatus) is a black hornbill with a bright red bill and bushy crest.

The 28" White-crested Hornbill (Tropicranus albocristatus) is a black hornbill with a very long graduated tail and a bushy white crest like a Mohawk haircut. It was a treat to find this bird as there are only 2 or 3 pairs in Uganda in the Semliki Forest along the Congo border.

White-crested Hornbill

We saw several species on monkeys in Uganda. The first is the well named Red-tailed Monkey (Cercopithecus ascanius). It is 40 - 60" in length with the tail being 60%. It is IDed by the red tail, white cheeks and nose. This monkey is in the same forest with the White-crested Hornbill above and the hornbill follows the monkeys as the monkeys shake the leaves and expose caterpillars which the hornbills eat.

Next is L'Hoest's Monkey (Allochrocebus lhoesti). It is about 45" long and 50% tail. It is a black monkey with a brown lower back and white around the neck.

The last is Patas Monkey (Erythrocebus patas). It is a large red haired monkey 60" in length and the tail is 50%. The males can weigh up to 40 pounds. The adults have a white face but the babies have a black face. They are mostly terrestrial.
