Relationship between developmental modes, flight styles, and wing morphology in birds

open access: yesThe European Zoological Journal, 2017
The aim of this work is to estimate the relationship between developmental mode and flight style, body mass and wing morphology of birds. We revealed high evolutionary correlation between developmental mode and flight style of birds.

Pellets recovered from stick nests and new diet items of Furnariidae (Aves: Passeriformes) [PDF]

open access: yes, 2014
This is the first record showing eleven species in seven genera of Furnariidae (Aves: Passeriformes) from Argentina that regurgitate pellets. A total of 627 nests of Furnariidae was examined, and from 84 nests (13.3%), 1,329 pellets were recovered. These

Birds With Distinct Ecological Traits Show Varied Haemoglobin Adaptations Along Elevation Gradients. [PDF]

open access: yesEcol Evol
Birds along elevation gradients provide unique insights into physiological adaptations to hypoxia. This study examined how ecological traits influence haemoglobin concentration in 920 birds across 133 species sampled along a 60–1600 m elevation gradient. Our findings show that haemoglobin increased with elevation, with a steeper rise in terrestrial and

Water bathing alters the speed-accuracy trade-off of escape flights in European starlings [PDF]

open access: yes, 2009
Birds of most species regularly bathe in water, but the function of this behaviour is unknown. We tested the hypothesis that water bathing is important in feather maintenance, and hence should enhance flight performance. We manipulated European starlings'

Citizen science reveals host‐switching in louse flies and keds (Diptera: Hippoboscidae) during a period of anthropogenic change

open access: yesMedical and Veterinary Entomology, EarlyView.
A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

Temperate-Tropical Variation in Breeding Synchrony and Extra-Pair Paternity Among New World Tachycineta Swallows

open access: yesScientific Reports, 2019
Extra-pair paternity rates vary markedly across avian taxa, but patterns of variation in this trait have been obscured by a paucity of data on closely related species, especially those spanning broad environmental gradients.

Flight Behavior of Individual Aerial Insectivores Revealed by Novel Altitudinal Dataloggers

open access: yesFrontiers in Ecology and Evolution, 2018
Swallows and martins (Aves: Hirundinidae) are well-studied with respect to their breeding biology, but major aspects of their individual aerial movement behavior and ecology are poorly understood.

A case of a Pustulated Carrion Beetle (Nicrophorus pustulatus, Coleoptera: Silphidae) burying live Tree Swallow (Tachycineta bicolor, Passeriformes: Hirundinidae) nestlings under the nest

open access: yes, 2020
The ecology of Pustulated Burying Beetle ( Nicrophorus pustulatus , Coleoptera: Silphidae) appears distinct among Nicrophorus species, with evidence of it parasitizing snake eggs and foraging primarily above the ground and into the forest canopy. Here we
