A systematic review and meta‐analysis of variation in nest predation of ground‐nesting birds

open access: yesIbis, EarlyView.
Predation and communities of predators of ground‐nesting bird nests and fledglings have been studied across multiple groups of ground‐nesting birds, such as waders, waterbirds, gamebirds and passerines, and habitats, but differences and similarities between groups are less studied.

The impact of roosting birds on the abundance of two groups of soil mesofauna

open access: yesStudia Ecologiae et Bioethicae, 2012
The aim of the study was to assess the influence of corvid urban roosts on the abundance of two groups of soil mesofauna: mites and springtails. Two areas located in the city of Warsaw were taken into consideration, one subjected to winter roosting ...

Population dynamics and reproductive success of Short‐eared Owls in relation to widely fluctuating food abundance and farmland habitat degradation

open access: yesIbis, EarlyView.
Populations of the Short‐eared Owl Asio flammeus have declined across Europe and North America, probably in response to habitat degradation driven by agricultural intensification. However, long‐term evidence linking farmland habitat change to variation in breeding density and reproductive success remains limited.

Warm temperatures during cold season can negatively affect adult survival in an alpine bird

open access: yesEcology and Evolution, 2019
Climate seasonality is a predominant constraint on the lifecycles of species in alpine and polar biomes. Assessing the response of these species to climate change thus requires taking into account seasonal constraints on populations.

Persecution by humans affects nest‐site selection of Hooded Crows: a comparison of an urban and two rural areas

open access: yesIbis, EarlyView.
The Hooded Crow, a bird species that once occurred only in agricultural areas, has colonized urban environments in the last 50–100 years in Europe. Apart from higher food availability, safer nesting sites, better thermoregulation and lower predation in cities, persecution through hunting, trapping or poisoning by humans in rural areas is an important ...

Proactive prosociality in a cooperatively breeding corvid, the azure-winged magpie (Cyanopica cyana) [PDF]

open access: yes, 2016
One of the contemporary hypotheses concerning the evolution of human altruism is the cooperative breeding hypothesis (CBH) which has recently been tested in non-human primates.

The Form of Agency

open access: yesNoûs, EarlyView.
ABSTRACT Philosophers often think agency is essentially connected with rationality, intention, or control. However, Minimalists argue that agency is just the power to cause a change; acids and boulders are agents too. Many philosophers treat Minimalism as a wild outlier, assuming its falsity without argument.

Less activity means improved welfare? How pair housing influences pinyon jay (Gymnorhinus cyanocephalus) behaviour

open access: yesAnimal Welfare
The activity level and specific behaviours exhibited by captive animals are crucial indicators of welfare. Stereotypies, or repetitive behaviours that have no apparent function or goal, are performed by animals experiencing poor conditions in their ...

T. rex cognition was T. rex‐like—A critical outlook on diverging views of the neurocognitive evolution in dinosaurs

open access: yesThe Anatomical Record, Volume 309, Issue 10, Page 2541-2559, October 2026.
Abstract A recent debate has emerged between Caspar et al. (2024) and Herculano‐Houzel (2023) on inferring extinct dinosaur cognition by estimating brain neuron counts. While thought‐provoking, the discussion largely overlooks the function of cognition, as well as partly neglects the difficulties involved in estimating neuron numbers, which according ...

Data for "Volitional control of vocalizations in corvid songbirds"

open access: yes, 2019
Using operant conditioning, we show here that carrion crows, songbirds of the corvid family, can exert control over their vocalizations. Further information can be found in the attached text-file "Data_Annotation.txt".
