Abstract

The subject of this thesis is research of behaviour of channel-billed toucans in captivity. The goal was to show diversity in behaviours through ethogram of the specimens held in the Zagreb Zoo pavilion - „Tropical house“ as well as to stimulate the expression of species specific behaviours through environmental enrichment techniques. We tested if the differences in feeding behavior depended on presentation of food (live insects and fruit), seasonal change (breeding and non-breeding season) or weather conditions. In 135 hours of observation with ad libitum sampling method, 57 behavioural units were described which shows that the exhibit allows for a large number of species specific behaviours. The differences in feeding behaviour were measured in 54 hours of observation with continuous sampling method. Mann-Whitney and Kruskal-Wallis test showed that the time spent in foraging, time spent in feeding and in food manipulation changes significantly depending on food presentation and seasonal change but to a lesser extent on weather conditions.
