Age-specific effects on reproductive performance of grassland songbirds nesting in agricultural habitats

Avian Conservation and Ecology, 2022
Clutch size and number of young fledged has been shown to increase with female age until approximately mid-life, when reproductive performance declines. We used a long-term dataset (2002–019) to investigate age-specific effects on reproductive parameters

Does a passerine hibernate? [PDF]

, 2019
ABSTRACT The thermal physiology of the highly endangered Rock Wren ( Xenicus gilviventris ) from New Zealand is examined. It is a member of the Acanthisittidae, a family unique to New Zealand.

Paler within the city: Carotenoid‐based colouration covaries negatively with the proportion of impervious surface in great tit (Parus major) territories across Europe

Journal of Animal Ecology, EarlyView.
Across six European cities, great tits in more impervious territories had paler carotenoid‐based plumage, but not lower brightness or UV chroma. This suggests that urban habitat imperviousness is associated specifically with lower carotenoid pigment deposition, rather than broad changes in feather reflectance or structural quality.

Unraveling Occurrence Patterns and Diversity of Avian Malaria Parasites in Iberian Obligate and Facultative Scavenger Birds

Integrative Zoology, EarlyView.
Low overall haemosporidian occurrence (3.4%; 13/383). Unexpected high lineage diversity (10 new host–parasite interactions). Novel Leucocytozoon lineage (GYPBAR01) in all European vultures except the griffon vulture. Plasmodium relictum (lineage SGS1) in adult red kites.

Isospora bocamontensis (Protozoa: Apicomplexa) in captive yellow cardinal Gubernatrix cristata (Passeriformes: Emberezidae) Isospora bocamontensis (Protozoa: Apicomplexa) em cardeais-amarelo Gubernatrix cristata (Passeriformes: Emberezidae) mantidos em cativeiro

Pesquisa Veterinária Brasileira, 2013
The yellow cardinal (Gubernatrix cristata) is a passerine found in southern Brazil, especially along the border with Uruguay and Argentina. It is an endangered species and its population is decreasing.

Nitrogen Isotopes Suggest Sex‐Based Diet Differences on the Breeding Grounds for a Sexually Monomorphic Migratory Passerine

Ecology and Evolution
Differential foraging by sex can have important implications for understanding the ecology of a species. This can be especially difficult to study through observations alone in sexually monomorphic species, such as the Golden‐crowned Sparrow (Zonotrichia

Genomic Content in Avian Haemosporidian Parasites Suggests Co‐Regulation of Apicoplast and Mitochondrial Nucleoids

Integrative Zoology, EarlyView.
Apicoplast genomic content and mitochondrial genomic content were found to be strongly correlated (rho = 0.93) for infections going from low to high. Apicoplast and mitochondrial genomic content were deemed as more predictive factors of parasitemia for different infection intensities.

Rapid sex determination of a wild passerine species using loop‐mediated isothermal amplification (LAMP)

Ecology and Evolution, 2019
Many bird species are sexually monomorphic and cannot be sexed based on phenotypic traits. Rapid sex determination is often a necessary component of avian studies focusing on behavior, ecology, evolution, and conservation. While PCR‐based methods are the
