Patterns of daily activity of Meyer's Parrot ( Poicephalus meyeri ) in the Okavango Delta, Botswana

Meyer's Parrots (Poicephalus meyeri) in the Okavango Delta exhibit weak bimodal daily activity patterns, with obligate feeding between 0830 and 1100 hours and seasonally required feeding between 1600 and 1830 hours to meet protein needs. This pattern is influenced by physiological constraints like crop-size limitations and climatic factors such as temperature fluctuations. Flight activity shows a bimodal pattern due to communal roosting and foraging behavior, while population estimates are highest during late morning counts (0830–1100 hours). The study highlights how environmental conditions and nutritional requirements shape the daily rhythms of these parrots, offering insights into their ecological adaptability.
