Monk and Rose-Ringed Parakeets

, 2017
Worldwide, there are about 350 species of parrots and parakeets (order: Psittaciformes). According to the analyses of Cassey et al. (2004), 54 of these species have been introduced to areas outside their native ranges, and 38 species have become established in the nonnative range. Humans exhibit ambivalent feelings toward parrots and parakeets. Many of

Multidrug-Resistant Extended-Spectrum Beta-Lactamase (ESBL) Producing Escherichia coli in Pet Birds of Bangladesh. [PDF]

Vet Med Sci
An alarming 43.83% of cloacal samples revealed multidrug‐resistant ESBL‐E. coli, with TEM being the most frequently detected resistance gene. These results underscore pet birds as hidden reservoirs of MDR pathogens, posing a potential threat to public health in Bangladesh. Routine surveillance and responsible antimicrobial use are crucial to mitigating

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

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 ...

Snowmelt predicts earlier breeding across the latitudinal range of an Arctic nesting seabird, the Little Auk (Alle alle)

Journal of Animal Ecology, Volume 95, Issue 7, Page 1248-1259, July 2026.
Multi‐year monitoring of the crevice‐nesting High Arctic seabird, the Little Auk (Alle alle), across four colonies spanning distinct climatic regimes revealed that snowmelt timing is a key and consistent driver of breeding phenology. Earlier snowmelt advances access to nesting habitat, enabling birds to initiate reproduction sooner. These findings show

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.
