Rapid responses of marsh birds to large‐scale tidal wetland restoration in California's Sacramento–San Joaquin Delta

open access: yesRestoration Ecology, EarlyView.
Abstract Introduction Tidal wetland restoration is widely used to recover ecosystem function in modified estuaries, yet uncertainty remains about how quickly wildlife communities respond. Early trajectories are central to evaluating restoration success, guiding adaptive management, and building ecosystem resilience in engineered landscapes. Marsh birds

Facultative development of courtship and communication in juvenile male cowbirds (Molothrus ater) [PDF]

open access: yesBehavioral Ecology, 2002
We investigated effects of naturally occurring variation in experience with adult males on development of song and courtship competence in captive juvenile cowbirds. We studied birds in groups housed in large outdoor aviaries that allowed birds to regulate access to social stimulation.

Testing a key assumption in animal communication: between-individual variation in female visual systems alters perception of male signals

open access: yesBiology Open, 2017
Variation in male signal production has been extensively studied because of its relevance to animal communication and sexual selection. Although we now know much about the mechanisms that can lead to variation between males in the properties of their ...

Sociability Under Anthropogenic Change: From Individual Behaviour to Population‐Level Consequences

open access: yesEcology and Evolution, Volume 16, Issue 10, October 2026.
Our review synthesises empirical and theoretical research on how anthropogenic environmental change reshapes animal social behaviour from individuals to populations. We use sociability as an individual‐level lens, distinguishing context‐dependent expression from repeatable interindividual differences and linking both to social relationships, network ...

Underestimation of avian diversity in the Tumbesian hotspot: Sampling gaps and conservation challenges

open access: yesConservation Science and Practice, Volume 8, Issue 10, October 2026.
This study provides the first comprehensive reassessment of avian diversity in the Tumbesian region in over 30 years, documenting 931 species and identifying significant sampling gaps driven by geographic accessibility. We reveal a critical misalignment between biodiversity value and current protection coverage, particularly in humid forests which ...

Group‐Specific Variation in Heterodyne Frequencies of Biphonic Calls in Resident (R‐Type) Killer Whales Orcinus orca ater

open access: yesMarine Mammal Science, Volume 42, Issue 4, October 2026.
ABSTRACT Biphonation—the simultaneous production of two independent fundamental frequencies within a single vocalization—is a prominent feature of killer whale calls, yet the factors influencing the presence and intensity of heterodyne frequencies, which arise from interactions between these fundamentals, remain poorly understood. We analyzed long‐term

Breeding Biology of Grassland Birds in Western New York: Conservation and Management Implications

open access: yesAvian Conservation and Ecology, 2010
Declining grassland breeding bird populations have led to increased efforts to assess habitat quality, typically by estimating density or relative abundance.

Effects of off‐highway vehicle activity on Arizona wildlife: a systematic literature review

open access: yesThe Journal of Wildlife Management, Volume 90, Issue 7, September 2026.
The published literature indicates that off‐highway vehicles (OHVs) predominantly negatively affect native Arizona amphibians, mammals, and reptiles, while effects of OHVs on native Arizona birds are mostly unknown or neutral. Abstract Off‐highway vehicle (OHV) recreation has dramatically increased in Arizona, USA, prompting concerns about potential ...

Responses of Female Yellow Warblers to Playbacks Signaling Brood Parasitism or Predation Risk: A Quasi-Replication Study

open access: yesAnimal Behavior and Cognition, 2021
Many avian species are negatively impacted by obligate avian brood parasites, which lay their eggs in the nests of host species. The yellow warbler (Setophaga petechia), which is host to the brood-parasitic brown-headed cowbird (Molothrus ater ...

Chewing Lice From the Wings of Migrating Shorebirds: Diversity, Host Specificity, and Associations With Host Body Condition

open access: yesEcology and Evolution, Volume 16, Issue 7, July 2026.
We investigated the diversity, prevalence, and abundance of chewing lice in 1403 individuals representing 20 migratory shorebird species from the families Charadriidae and Scolopacidae, identifying 26 louse species through microscopy and DNA barcoding.
