A novel gene organization of the rock sparrow Petronia petronia (Aves: Passeriformes) revealed by complete mitochondrial genome

open access: yesMitochondrial DNA. Part B. Resources, 2017
The whole sequence of the Rock Sparrow (Petronia petronia) mitochondrial genome was determined using La-PCR and conserved primer walking approaches. The entire mitogenome was 17,426 bp in length and harboured 13 protein-coding genes, 2 rRNA genes, 23 ...

Mitochondrial Gene Diversity and Host Specificity of Isospora in Passerine Birds

open access: yesFrontiers in Veterinary Science, 2022
Isospora infections are common in both wild and captive passerine species. Many bird species have been shown to have co-evolved with a particular species of Isospora.

Genetic and phenotypic divergence in an island bird: isolation by distance, by colonization or by adaptation? [PDF]

open access: yes, 2014
Discerning the relative roles of adaptive and nonadaptive processes in generating differences among populations and species, as well as how these processes interact, is a fundamental aim in biology.

Year-round tracking of small trans-Saharan migrants using light-level geolocators [PDF]

open access: yes, 2010
Since 1899 ringing (or banding) remained the most important source of information about migration routes, stopover sites and wintering grounds for birds that are too small to carry satellite-based tracking systems. Despite the large quantity of migrating

The evolution of sperm morphometry in pheasants [PDF]

open access: yes, 2007
Postcopulatory sexual selection is thought to be a potent evolutionary force driving the diversification of sperm shape and function across species. In birds, insemination and fertilisation are separated in time and sperm storage increases the duration

Avian malaria is absent in juvenile colonial herons (Ardeidae) but not Culex pipiens mosquitoes in the Camargue, Southern France [PDF]

open access: yes, 2015
Apicomplexan blood parasites Plasmodium and Haemoproteus (together termed “Avian malaria”) and Leucocytozoon are widespread, diverse vector-transmitted blood parasites of birds, and conditions associated with colonial nesting in herons (Ardeidae) and ...

Diet contributes to urban-induced alterations in gut microbiota : experimental evidence from a wild passerine [PDF]

open access: yes, 2020
Urban sprawl increasingly affects the ecology of natural populations, including host-microbiota interactions, with observed differences in the gut microbiota between urban and rural hosts.

A comparative study of the function of heterospecific vocal mimicry in European passerines [PDF]

open access: yes, 2007
Although heterospecific vocal imitation is well documented in passerines, the evolutionary correlates of this phenomenon are poorly known. Here, we studied interspecific variation in vocal mimicry in a comparative study of 241 European songbirds.

Using large-scale citizen science ringing data as a means of calculating maximum longevity in birds

open access: yesBothalia: African Biodiversity & Conservation, 2019
This article calculates estimates of avian longevity for southern African Passeriformes and demonstrates the impact citizen scientists have on data volumes curated by the South African Bird Ringing Unit (SAFRING).

Morphology and biomechanics of the nests of the Common Blackbird Turdus merula [PDF]

open access: yes, 2015
Capsule Common blackbirds select different materials, with varying biomechanical properties, to construct different parts of their nest. Aims This study tested the hypothesis that outer components of a nest have a more structural role and so are ...
