Predatory functional morphology in raptors: interdigital variation in talon size is related to prey restraint and immobilisation technique.

open access: yesPLoS ONE, 2009
Despite the ubiquity of raptors in terrestrial ecosystems, many aspects of their predatory behaviour remain poorly understood. Surprisingly little is known about the morphology of raptor talons and how they are employed during feeding behaviour.

Notes about food consumption strategies of the Crane hawk: (Geranospiza caerulescens) (aves, accipitridae) on Cane toad: Rhinella marina

open access: yesInternational Journal of Avian & Wildlife Biology
The Crane Hawk: Geranospiza caerulescens is one of the most common raptors in forests and open lands across Central and South America. Little is known about its eating habits, even less about the type of consumption strategy the bird applies to its prey.

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 ...

Latitudinal Variation in the Timing of Nest Predator Activity Is Habitat Specific

open access: yesGlobal Ecology and Biogeography, Volume 34, Issue 1, January 2025.
ABSTRACT Aim The goal of this work was to investigate whether the community of avian nest predators shifts from nocturnal to diurnal with changes in latitude. This hypothesis was formulated 70 years ago, under the rationale that longer day length during the bird breeding season at high latitudes increases opportunities for visual predators.
