Abraham Tolcha, Matewos Masne, Belayneh Ayechw

TL;DR
This study examines the diet of Mantled guerezas in Ethiopia's Maze National Park, finding they show seasonal dietary flexibility based on food availability.
Contribution
The study provides the first up-to-date data on the feeding ecology of Colobus guereza in Maze National Park.
Findings
Trichilia emetica was the most consumed plant species in both wet and dry seasons.
Young leaves were preferred in the wet season, while mature leaves were more common in the dry season.
Unidentified invertebrates were rarely consumed, indicating a primarily plant-based diet.
Abstract
Knowledge of feeding ecology is essential for effective management of a primate and its habitat. The Mantled guereza Colobus guereza is a predominantly folivorous monkey that occurs in different parts of eastern Africa, including the Maze National Park in Ethiopia. Despite many studies conducted in the area, there is no up-to-date data that was carried out on feeding ecology of the Colobus guereza. The aim of this study is to determine the dietary composition and feeding preference of the Colobus guereza in the park. To better understand this, we randomly selected three study groups along the Maze River. We used instantaneous scan sampling method to collect feeding data from September 2021–August 2022. We followed guerezas from 6:30 to 10:30 in the morning and 13:30 to 17:25 in the afternoon collecting feeding activity data between 5 min intervals during 10-min scan duration. Overall,…
