Parental Provisioning in an Urban Apex Predator [PDF]
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.

Common cuckoo eggs are more resistant to puncture by the host [PDF]
The puncture resistance hypothesis suggests that thick-shelled eggs of parasitic birds can resist puncture-ejection by the host. However, few experiments have yet been conducted to test this hypothesis in terms of natural host behavior (e.g., pecking at ...

Unmasking Budgerigar Splenic Leukocyte Populations With Single-Cell Transcriptomics and Multiplex RNA In Situ Hybridization [PDF]
The current understanding of the avian immune system primarily stems from research conducted in chickens, given their economic significance as a food source. Extending the research to other avian species like Psittaciformes requires the use of label-free

Do domestic budgerigars perceive predation risk? [PDF]
Predation risk may affect the foraging behavior of birds. However, there has been little research on the ability of domestic birds to perceive predation risk and thus adjust their feeding behavior.

Experimental studies of social foraging in budgerigars, Melopsittacus undulatus [PDF]
Many animals are social foragers. Foraging with others may confer a number of advantages, but is also likely to present a number of challenges that are not encountered by solitary foragers.

The interaction between native and exotic species can cause changes both in the food-chain and in aspects of competition for trophic resources, such as predation. Predatory events are common in nature, but difficult and usually recorded opportunistically.

Memory-specific correlated neuronal activity in higher-order auditory regions of a parrot
Male budgerigars (Melopsittacus undulatus) are open-ended learners that can learn to produce new vocalisations as adults. We investigated neuronal activation in male budgerigars using the expression of the protein products of the immediate early genes ...
