Causes and consequences of material variation in avian nest building

Journal of Avian Biology, Journal Year: 2025, Volume and Issue: 2025(2)

Published: March 1, 2025

Houses around the world are built with a variety of materials like timber and brick, depending on number factors such as local climate material availability. Similarly, non‐human animals birds use diverse to build nests. Very little is known about how choose nest materials, these choices, in turn, affect function nests they build. As an initial attempt address this question, we investigated causes consequences nest‐material by Dartford warblers Sylvia undata . The breeding England show considerable variation materials: some made almost entirely heather, while others contain lot grass. We found that warbler were explained composition habitats, but no evidence for relationships between insulation capacity or performance. Warblers appear be able equally functional using whatever readily available respective habitats. Studying nest‐building behaviour individual species could inform animal architecture evolved.

Plumage and eggshell colouration covary with the level of sex-specific parental contributions to nest building in birds

The Science of Nature, Journal Year: 2024, Volume and Issue: 111(2)

Abstract Interspecific variation in sex-specific contributions to prenatal parental care, including avian nest building, is becoming increasingly better understood as we amass more information on species. We examined whether building covary with the colouration of parents and their eggs 521 species Western Palearctic birds. Having colourful plumage laying are costly because deposition pigments feathers and/or forming nanostructural substrates feathers, so it might be expected that those costs at level individuals across produce a suite codivergent traits. Using phylogenetically informed approach, tested hypothesis which females alone invest energy nests exhibit less sexual dichromatism. However, found comparative support for opposite this prediction. then build lay colourful, costlier, dual can only borne by higher quality individuals. As expected, or together males likely colourfully pigmented relative nests. Finally, stochastic character mapping provided evidence repeated evolution female-only building. sex differences therefore complex manner female pre- (nest building) post-copulatory (egg production) investment reproduction.

Sex and age differences in the preference for materials for the communal nests of sociable weavers Philetairus socius

Abstract Many animals build structures that are used for shelter, reproduction or to capture prey. The type of material these is likely influence their solidity, thermoregulation capacity and, in some species, may the attractiveness builders. In case animal nests, evidence preference nesting has been documented several species but, date, few field experiments have conducted, and it was seldom investigated whether individuals' attributes affected those preferences. We preferences relation individual on sociable weavers ( Philetairus socius ) communally one largest known nest structures, using dry grass. conducted an experiment where we presented two piles straws, long short, wild individuals. recorded 900 h video a deep learning method automatically detect images birds were present (266 colour‐ringed individuals).

The evolution of using shed snake skin in bird nests

AbstractMany species of birds use shed snake skin in nest construction, but this behavior remains poorly understood. Ecological context is likely key for understanding how unusual, widespread, evolved. We comparative and experimental approaches to suggest that the evolution mediated by morphology predator communities. First, we reviewed literature found 78 from 22 families have been reported construction. All one these are passerines and, using analyses, show disproportionately observed cavity-nesting species. Second, examined a subsample North American species, all which see whether proportion nests with differs between cavity- open cup-nesting This analysis suggested roughly 6.5 times higher than Finally, used series experiments comparisons test four hypotheses whereby could award fitness benefits (nest predation, microbiotas, ectoparasites, social signaling) support predation hypothesis. Snake reduced cavity, not cup, nests. These unequal highlight different ecological conditions morphologies explains why, across more frequently birds.

Urban green spaces with high connectivity and complex vegetation promote occupancy and richness of birds in a tropical megacity

Urban Ecosystems, Journal Year: 2024, Volume and Issue: 28(1), P. 1 - 18

Abstract Urban growth often leads to land-use changes that result in biodiversity loss and reduced human benefits. In urban zones, green areas facilitate physicochemical processes (such as carbon capture, reducing environmental temperature noise pollution), offer multiple benefits beings (e.g., water filtration purification), support numerous vertebrate populations, including birds. the tropics, capacity of spaces maintain bird populations is regulated by characteristics these vegetation structure) seasonality. order generate ecological knowledge help conserve diversity large settlements, this study aimed (1) identify most influential variables on distribution species a tropical megacity, (2) assess how richness varies between dry rainy seasons.

Ecology and conservation of cavity-nesting birds in the Neotropics: Recent advances, future directions, and contributions to ornithology

Ornithological Applications, Journal Year: 2024, Volume and Issue: unknown

Published: Aug. 30, 2024

ABSTRACT About 35% of tree-cavity-nesting bird species inhabit the Neotropics, a region crucial to understanding their breeding ecology, conservation, and roles in social-ecological systems. Sixteen years ago, Cornelius et al. (2008) reviewed published knowledge identified research priorities for Neotropical cavity-nesting birds. Advances since 2008 have not been synthesized many remain excluded from dominant ornithology because barriers that disproportionately affect people ideas Global South. Here, we review recent advances about birds, introduce Special Feature series “Ecology conservation cavity nesters Neotropics,” outline possible directions future research. Research Neotropics has advanced biology, demonstrated nest sites are limited birds compete cavities (mainly humid forests), non-excavated (formed by wood decay) as main source importance Indigenous local community relationships With field studies across shows how environment, people’s common imaginaries, vegetation management, behavior avian excavators can interact influence availability, with ecological consequences cavity-using organisms. In future, researchers should center ethno-knowledge natural history create an accurate list integrate this into population ecology. It is also important study factors dynamics, especially using systems framework arid semi-arid regions.
