Balancing conflict and coexistence: Interactions between invasive monk parakeets and native urban birds

Ecological Applications, Volume 36, Issue 4, June 2026.
Abstract Biological invasions often generate complex ecological paradoxes, particularly when invasive species act as ecosystem engineers that simultaneously compete with and benefit native communities. Understanding these dual dynamics is critical for managing urban biodiversity.

“Kill Two Birds with One Stone”: Urban Tree Species Classification Using Bi-Temporal Pléiades Images to Study Nesting Preferences of an Invasive Bird

Remote Sensing, 2017
This study presents the results of object-based classifications assessing the potential of bi-temporal Pléiades images for mapping broadleaf and coniferous tree species potentially used by the ring-necked parakeet Psittacula krameri for nesting in the ...

Mapping breeding birds in a re-naturalized historical fortress: composition, structure and considerations about abundance vs. biomass comparisons

Rivista Italiana di Ornitologia - Research in Ornithology, 2023
Using the mapping method, I obtained data about a rich, even and diversified breeding bird assemblage inhabiting an abandoned and re-naturalized historical military fortress (Rome, central Italy).

Beyond species loss: Community reshuffling shapes biodiversity along the urban–rural gradient

Journal of Applied Ecology, Volume 63, Issue 6, June 2026.
Our results indicate that species turnover is a general ecological mechanism shaping vertebrate communities along the urban gradient, driven by taxon‐ and species‐specific responses to environmental and spatial features. Community differences primarily reflect habitat suitability rather than dispersal limitation, highlighting the potential of targeted ...

BREEDING STATUS AND NEST CHARACTERISTICS OF ROSERINGED (PSITTACULA KRAMERI) AND ALEXANDRINE PARAKEETS (PSITTACULA EUPATRIA) IN ISTANBUL’S CITY PARKS

Applied Ecology and Environmental Research, 2019
Invasive non-native parakeet populations are increasing throughout Europe with proved negative impact on native fauna and Turkey is no exception. Rose-ringed and Alexandrine parakeets have established populations in Turkey's large cities but even basic distribution, abundance and breeding behaviour information is missing. This study aims at determining

Induction of blindness by formoguanamine hydrochloride in adult male roseringed parakeets (Psittacula krameri)

Journal of Biosciences, 2002
Formoguanamine (2,4-diamino-s-triazine) was known to be an effective chemical agent in inducing blindness in poultry chicks, but not in adult birds. The present study was undertaken to demonstrate the influences, if any, of this chemical on the visual performance and retinal histology in an adult sub-tropical wild bird the roseringed parakeet ...

Landscape Structure Shapes the Equilibrium Between Migratory and Sedentary Species in Avian Breeding Communities Along an Altitudinal Gradient

Journal of Biogeography, Volume 53, Issue 1, January 2026.
ABSTRACT Aim Human land use shapes landscapes and threatens avian biodiversity, yet its interaction with altitudinal gradients and the consequences for the assembly of long‐distance migratory and sedentary bird communities remain poorly understood. Location Southern France. Taxon Avian breeding communities.

Diet to tissue discrimination factors for the blood and feathers of the monk parakeet (Myiopsitta monachus) and the ring-necked parakeet (Psittacula krameri)

Animal Biodiversity and Conservation, 2019
Stable isotope analyses (SIAs) have been widely used in recent years to infer the diet of many species. This isotopic approach requires using diet to tissue discrimination factors (DTDFs) for each prey type and predator tissue, i.e., to determine the ...
