Parental care and bird embryonic metabolism: A comparison between uniparentally incubating Silver‐throated Tits and biparentally incubating Black‐throated Tits

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Studies have shown that organisms may adjust metabolic rates in response to thermal variability, highlighting metabolic plasticity as a key adaptive mechanism. Understanding the extent of metabolic plasticity of an organism is key to predicting its adaptation to climate

Nocturnal Songbird Migration [PDF]

open access: yesNature, 1971
WE would like to comment on Evans's criticisms1 of our recent article2 concerning the influence of wind on the direction of nocturnal songbird migration. We pointed out that problems in identifying bird types from radar echoes may have contributed to the controversy about passerine nocturnal migrants compensating for wind drift. Evans claims that there

Diet, phenology and body size shape nutrient release by songbirds

open access: yesFunctional Ecology, EarlyView.
Read the free Plain Language Summary for this article on the Journal blog. Abstract Animals can dramatically alter ecosystem structure and function through the cycling and transport of nutrients in their waste. While birds are particularly capable of influencing nutrient cycles due to their high mobility, abundance, metabolism and functional diversity,

The songbirds as an inspiration for Byzantine kratēmata [PDF]

open access: yesMuzikologija
Byzantine kratēmata, widely known as the terrirem, as part of other, broader musical works, date approximately back to the eleventh-twelfth century. A small group of four kratēmata are named after birds (Aēdhon - Luscinia megarhynchos, Potamis -

Differential reliance on aquatic prey subsidies influences mercury exposure in riparian arachnids and songbirds

open access: yesEcology and Evolution, 2021
Cross‐ecosystem subsidies move substantial amounts of nutrients between ecosystems. Emergent aquatic insects are a particularly important prey source for riparian songbirds but may also move aquatic contaminants, such as mercury (Hg), to riparian food ...

Ecophysiology of an Avian Invader: Body Condition and Metabolic Rate Adjustments to Ambient Temperature

open access: yesIntegrative Zoology, EarlyView.
This study examines the ecophysiological responses of common waxbills to temperature variation in Portugal. We measured body condition and basal metabolic rate (BMR) during summer and winter across two regions in Portugal. Body condition was negatively correlated with temperature, while the relationship between BMR and temperature varied seasonally. In

Urbanization and brood parasitism affect growth, but not free amino acid concentrations in nestling song sparrows (Melospiza melodia)

open access: yesFrontiers in Bird Science
Urbanization is projected to grow rapidly in the coming decades. Several consequences of this form of anthropogenic change for ecosystems and individuals are described by the fields of urban ecology and urban ecophysiology, respectively.

Thresholding species distribution models: Simple approaches for land‐use planning in multifunctional landscapes

open access: yesMethods in Ecology and Evolution, EarlyView.
Abstract Species distribution models (SDMs) are often used to understand changes to species' distributions and their habitats under different land‐use scenarios, enabling decision makers to prioritize areas for management efforts and balance environmental conservation with socio‐economic demands on the landscape.

Living on the edge: Predicting songbird response to management and environmental changes across an ecotone

open access: yesEcology and Evolution, 2023
Effective wildlife management requires robust information regarding population status, habitat requirements, and likely responses to changing resource conditions.
