, 2016 Since their introduction to the United States in the 1960s, monk parakeets (Myiopsittamonachus) have thrived. Monk parakeets often construct nests on man-made structures, such as electric utility facilities and cell phone towers. Monk parakeets are non-native and not protected by the Federal Migratory Bird Treaty Act.

Ontogeny of foraging behaviour in an opportunistic gull inhabiting urban marine ecosystems
Wildlife Biology, EarlyView.Urbanization affects ecosystems by reducing biodiversity and displacing species from native habitats. While some suffer, others, like urban wildlife, adapt through innovative feeding and behaviours that improve their fitness in human‐altered settings. Despite research on wildlife in urban areas, the development of foraging behaviour in urban species is

Ibis, EarlyView.Fine‐scale genetic structure in animal populations can create opportunities for both kin‐directed co‐operation and kin competition. Knowledge of kinship is therefore key to understanding the selective pressures shaping sociality as well as the effects of social behaviour on local genetic structure.

Sex and Age Effects on Monk Parakeet Home-Range Variation in the Urban Habitat
Diversity, 2021 Home-range size is a key aspect of space-use, and variation in home-range size and structure may have profound consequences for the potential impact of damage and control strategies for invasive species.

A Cross‐Sectional Study on Parakeets Feeding and Housing Practices in Italy
Journal of Animal Physiology and Animal Nutrition, EarlyView.ABSTRACT Italy has one of the largest companion bird populations in Europe. This study aimed to investigate feeding and housing practices among Italian parakeet owners. An online questionnaire was distributed, yielding 433 voluntary responses. Participants were classified as hobbyists (HBY; ≤ 13 birds owned) or breeders (BRD; > 13 birds owned) to ...

Variation in parrot jaw musculature
The Anatomical Record, Volume 309, Issue 9, Page 2519-2533, September 2026.Interspecific morphological differences in some superficial jaw muscles of parrots. Abstract Psittaciformes, the order encompassing parrots and their relatives, are highly diverse and generally known for having a strong beaks used for multiple behaviors. The muscles related to the masticatory apparatus should reflect this functional complexity; however,

Journal of Morphology, Volume 287, Issue 8, August 2026.Integration of detailed hindlimb anatomy with biomechanical analyses demonstrates that pedal performance in the red‐and‐green macaw is driven by specialized muscle architecture and force distribution. Hypertrophy of digit IV flexor musculature, together with modifications of the intrinsic and extensor muscles, enhances grasping stability, climbing, and
