How Passive Acoustic and Traditional Monitoring Estimate Bird Diversity Across Habitats

Remote Sensing in Ecology and Conservation, EarlyView.
We compared traditional bird counts (PC) with passive acoustic monitoring (PAM) in a heterogeneous Alpine landscape. PAM recorded twice as many species, with a strong correlation between species richness and the bird counts (rs = 0.71); however, there were significant differences depending on habitat type.

EVOLUTION OF THE PASSERINE BIRDS

Vrapčarice (Passerine) je red ptica najbrojniji vrstama. Dijeli se na dva podreda - Oscine (Pjevice) i Suboscine (Ne-pjevice). Vrapčarice su monofiletička skupina ptica. Prve pjevice su se pojavile na južnoj Zemljinoj hemisferi u ranom tercijaru.

Passeriformes: nest predators and prey in a Neotropical Savannah in Central Brazil

Zoologia (Curitiba), 2009
The identification of predators of birds' nests, crucial to a better understanding of predator-prey interactions, remains poorly known. Here we provide evidence that birds, and especially passerines, may depredate birds' nests in the Cerrado (Neotropical

Sperm length variation as a predictor of extrapair paternity in passerine birds. [PDF]

PLoS ONE, 2010
The rate of extrapair paternity is a commonly used index for the risk of sperm competition in birds, but paternity data exist for only a few percent of the approximately 10400 extant species.

Passerine morphology: external measurements of approximately one‐quarter of passerine bird species [PDF]

Ecology, 2017
AbstractStudies of community organization and clade diversification that include functional traits have become an important component of the analysis of ecological and evolved systems. Such studies frequently are limited by availability of consistently collected data. Here, I present a data set including eight measurements of the external morphology of

Cotton Farming Pesticides Affect Ileal Microbiota Activity and Expression of Virulome but Not Resistome or Metabolic Pathways in a Sedentary Wild Passerine

Environmental Toxicology, EarlyView.
ABSTRACT The increased use of agrochemicals to enhance crop production has had detrimental environmental effects including implication in the sharp decline of North American farmland‐breeding birds. Here, using a combination of deep shotgun metatranscriptomics and pesticide exposure data, we sought to assess whether exposure to cotton (Gossypium spp ...

Torpor‐assisted migration: Regular use of shallow torpor reduces rest‐phase energy expenditure for songbirds during migration

Journal of Animal Ecology, EarlyView.
Migrating songbirds regularly use shallow torpor (up to 98% of birds for some species) to save energy (up to 42%) during inactive periods. This Ruby‐crowned Kinglet Corthylio calendula that was captured after a spring snowstorm highlights the value of being able to save energy when encountering unfavourable conditions.

Datasets of Bird Species Composition in a Land Reclamation Area of Lake Kahokugata, Central Japan, in Relation to Various Farmland Types

Ecology and Evolution
Agricultural intensification and land reclamation have transformed natural wetlands into farmland across East Asia, which has been a threat to bird diversity, particularly wetland and grassland specialists.

Fruiting Season Length Restricts Global Distribution of Female-Only Parental Care in Frugivorous Passerine Birds. [PDF]

PLoS ONE, 2016
Food availability is known to influence parental care and mating systems in passerine birds. Altricial chicks make uni-parental care particularly demanding for passerines and parental investment is known to increase with decreasing food availability.

Early‐life environment drives long‐term decrease in adult body mass in a wild bird population

Journal of Animal Ecology, EarlyView.
Using more than 90,000 body mass measures of adult and nestling great tits Parus major, we show that the 1 SD decline in adult mass between 1978 and 2024 is a consequence of changes in the environment (i.e. increase in population density) experienced at early life.
