Underestimated Fatalities of a Cryptic Avian Species of Conservation Concern at Wind Energy Facilities in California, USA. [PDF]
Blackbirds killed at wind turbines in California, USA, are typically assumed to be common red‐winged blackbirds. In reality, a surprising number of them are endangered tri‐colored blackbirds. This finding has important implications for the way fatalities are managed at these wind facilities. ABSTRACT Accurate information underpins successful ecological

Double Parasitism by Two Cuckoo Gentes in a Daurian Redstart Nest. [PDF]
Double parasitism is rare in forest‐breeding hosts of the common cuckoo, where females typically defend exclusive territories. We report a unique case in a Daurian redstart nest involving two different cuckoo gentes, despite one gens overwhelmingly dominating parasitism events in the population. This observation suggests that female cuckoos may be less

Farming Behavior by the Large Hawk-Cuckoo Toward the Silver-Eared Mesia and Black-Streaked Scimitar Babbler. [PDF]
Some parasitic birds may destroy unsuitable host nests through “Farming behavior” to induce re‐nesting, thereby creating new opportunities for parasitism. Despite its potential significance, this behavior has been documented in only a few brood‐parasitic species.

Clutch Destruction by Common Cuckoos (<i>Cuculus canorus</i>) During the Laying Stage of Vinous-Throated Parrotbills (<i>Sinosuthora webbiana</i>): First Video Evidence. [PDF]
We present the first video‐documented evidence of clutch destruction by Common Cuckoos during the laying stage of Vinous‐throated Parrotbills. This behavior, observed across five cases, led to complete clutch loss and host desertion. Our findings expand the known timeline of brood parasite aggression and offer new insights into host–parasite ...

Climatic Variability Threatens Population Growth and Persistence of a Declining Grassland Songbird. [PDF]
Determining the factors responsible for population change in threatened populations and the degree to which changing climates might put those populations at risk is one of the most pressing roles of conservation science. We tested whether increasing variability in weather could have driven recent declines in songbird population numbers using detailed ...

Do nest size and shape characteristics affect nest parasitism rates?
Brown‐headed cowbirds (Molothrus ater) are obligate brood parasites that lay eggs in host species’ nests. Studies on effects of host nest characteristics (e.g., nest placement, concealment, nest size) on parasitism rates by brown‐headed cowbirds have ...

Using 3D printed eggs to examine the egg-rejection behaviour of wild birds [PDF]
The coevolutionary relationships between brood parasites and their hosts are often studied by examining the egg rejection behaviour of host species using artificial eggs.

Predicting Metapopulation Responses To Conservation In Human-Dominated Landscapes
Loss of habitat to urbanization is a primary cause of population declines as human-dominated landscapes expand at increasing rates. Understanding how the relative effects of different conservation strategies is important to slow population declines for ...

Social brains in context: lesions targeted to the song control system in female cowbirds affect their social network. [PDF]
Social experiences can organize physiological, neural, and reproductive function, but there are few experimental preparations that allow one to study the effect individuals have in structuring their social environment. We examined the connections between

Ultraviolet-reflective film applied to windows reduces the likelihood of collisions for two species of songbird [PDF]
Perhaps a billion birds die annually from colliding with residential and commercial windows. Therefore, there is a societal need to develop technologies that reduce window collisions by birds.
