Birds under pressure: associations of highly‐, moderately‐, and lowly‐abundant birds with landscape and local variables in a dense Neotropical city

open access: yesJournal of Avian Biology, Volume 2025, Issue 5, September 2025.
Urban ecological studies often emphasize the role of vegetation‐related factors in promoting local biodiversity, but less attention has been given to human‐related factors, especially in tropical assemblages dominated by native species. In this study, we assessed the role of landscape and local variables in bird species richness and abundance in ...

Adaptiveness of Cattle Egret’s (Bubulcus ibis) foraging

open access: yesZoos' Print Journal, 2000
Cattle Egrets (Bubulcus ibis) feeding in close association with cattle catch insect prey at a significantly higher rate and expend less energy than do those foraging alone. Cattle Egrets once had a strong association with grazing cattle, but have now shifted themselves behind tractors specially in inundated agricultural fields. Captures per minute were

Amount of Organic Waste Affects the Composition and Interactions of Vertebrate Scavengers at Gambian Slaughterhouses

open access: yesAfrican Journal of Ecology, Volume 63, Issue 4, June 2025.
ABSTRACT Slaughterhouses in The Gambia serve as critical feeding sites for diverse vertebrate scavenger communities, including hooded vultures, domestic dogs, pigs and avian species such as pied crows, black kites and cattle egrets. This study investigated how the quantity and type of organic waste influence the composition and competitive interactions

Alien range size, habitat breadth, origin location, and domestication of alien species matter to their impact risks

open access: yesIntegrative Zoology, Volume 20, Issue 3, Page 520-534, May 2025.
We collected information on 1071 established alien terrestrial vertebrate species (mammals, birds, reptiles, and amphibians) and created a comprehensive database of 108 alien species to assess their impact risks and examined the generality of relationships between the impact risks and species characteristics.

Trends of some wintering waterbirds in Lazio (1993-2006)

open access: yesRivista Italiana di Ornitologia - Research in Ornithology, 2012
Since the 90s, censuses of wintering waterfowl have been carried out in the main wetlands of Lazio. We analysed the trends of 31 species in the 1993-2006 period (base year 1993) by means of TRIM (Trends and Indices Monitoring data) software (Model 3 ...

Visual fields, foraging and collision vulnerability in gulls (Laridae)

open access: yesIbis, Volume 167, Issue 2, Page 386-396, April 2025.
Wide variation in visual field configuration has been recorded among avian species and it is hypothesized that this variation is driven primarily by foraging ecology and predator detection. It has also been shown that visual field configurations can render some species more vulnerable to collisions with human artefacts that extend into open airspace ...
