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

Fine‐scale genetic structure in co‐operatively breeding Palmchats (Dulus dominicus) suggests mixed kinship in compound nests

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.

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 ...

Non‐native parrot species expand the trait space of avian communities by filling empty niches in urban areas

Ibis, Volume 168, Issue 3, Page 1055-1070, July 2026.
Non‐native species are one of the greatest threats to biodiversity worldwide due to their direct and indirect effects on native communities. There are two opposing hypotheses to explain how non‐native species successfully establish outside their native range.

Biology of Invasive Monk Parakeets in South Florida

The Wilson Journal of Ornithology, 2012
Abstract Monk Parakeets (Myiopsitta monachus) have been in Florida for >40 yrs, having been imported by the thousands for the pet trade. This conspicuous, charismatic species is now widely established, but relatively little is known about its population biology outside South America.

Patterns and Factors Influencing Parrot (Order: Psittaciformes) Success in Establishing Thriving Naturalized Populations within the Contiguous United States

Animals, 2023
Parrots (Order: Psittaciformes) represent one of the most striking and ecomorphologically diverse avian clades, spanning more than two orders of magnitude in body size with populations occupying six continents.

The impacts of biological invasions

Biological Reviews, Volume 101, Issue 3, Page 1255-1310, June 2026.
ABSTRACT The Anthropocene is characterised by a continuous human‐mediated reshuffling of the distributions of species globally. Both intentional and unintentional introductions have resulted in numerous species being translocated beyond their native ranges, often leading to their establishment and subsequent spread – a process referred to as biological

Genetic relatedness in Monk Parakeet breeding trios

Journal of Ornithology, 2016
Monk Parakeets (Myiopsitta monachus) are cooperative breeders, which means that one adult helps the breeding pair (trios). We found a breeding trio composed of two males and one female in a single breeding chamber of a two-chamber compound nest. Males were full siblings. The female was the half sibling of both males.

“The Unbearable Green Demon”: A Critical Analysis of Press Representation around the Extermination of Monk Parakeets in Madrid

Journalism and Media, 2022
We examine the press representation of monk parakeets (Myiopsitta monachus) and their population management in Madrid city. To do this, we analyze mentions of this species in six Spanish newspapers for the case of Madrid.

The Number and Distribution of Introduced and Naturalized Parrots

Diversity, 2021
Parrots have been transported and traded by humans for at least the last 2000 years and this trade continues unabated today. This transport of species has involved the majority of recognized parrot species (300+ of 382 species).
