Parental Provisioning in an Urban Apex Predator [PDF]
Ecology and Evolution, Volume 15, Issue 12, December 2025.We combine high‐definition webcams and citizen science to explore parental care in urban peregrine falcons from 30 locations across England between 2020 and 2023. By analysing detailed webcam footage, we quantified changes in prey type and delivery rates as chicks developed.

Food Preferences of Captive Rose-ringed Parakeets: a Comparison of Two Methods
Japanese Journal of Ornithology, 1993 Preference of captive Rose-ringed Parakeets Psittacula krameri for grains of sorghum, maize and rice was studied in multiple choice tests using two methods. The first method involved providing equal amount of three types of food daily to 15 individually caged parakeets. In the second method, the same parakeets were fasted overnight and then offered the
