Ecology And Influence Of Age And Habitats On The Diurnal Activity Patterns Of Cattle Egret (Bubulcus Ibis)

[Full Text]

Key words: Cattle egrets, Diurnal activity, Activity budget, Ecology, Conservation



Abstract: It was found that habitat types and age may influence diurnal activities of cattle egrets. In average, the grassland comprised 41.59% of all of diurnal activities, while forest and bushland comprised 21.54% and 35.79% of all of diurnal activities respectively (P<0.05). Variation in the performance of diurnal activities overtimes of the day differed significantly (P<0.05), similarly, the time spent by cattle egrets to perform diurnal activities was different (P<0.05). Activity budget of cattle egrets differed significantly with age classes (P>0.05). The adult cattle egrets spent much time feeding than sub-adults and juveniles. The feeding behaviour was the diurnal activity of cattle egrets performed most often in the morning hours. The diurnal activity patterns and time budgets of the cattle egrets may be due to their strategies to cope with environmental factors such temperatures, different habitats and food availability; and high foraging behaviour can be due to high energy demand.
