Vocal mimicry in Corvids [PDF]
Animal CognitionVocal mimicry, the copying of sounds produced by another species or the environment, is commonly described in vocal learners, such as songbirds. Understanding the functions of vocal mimicry can help to uncover the evolutionary drivers of vocal learning ...

Wild jackdaws recognise the contact calls of their mate [PDF]
Animal CognitionIn stable social environments, the ability to recognise other group members and integrate individual cues with previous experience is likely to be beneficial in mediating social interactions.

Occurrence of Chlamydiae in Corvids in Northeast Italy
Animals, 2022 Chlamydiaceae occurrence has been largely evaluated in wildlife, showing that wild birds are efficient reservoirs for avian chlamydiosis. In this study, DNA extracted from cloacal swabs of 108 corvids from Northeast Italy was screened for Chlamydiaceae ...

The Neophobia Hypothesis: nest decoration in birds may reduce predation by corvids [PDF]
Royal Society Open ScienceMany birds suffer heavily from nest predation, selecting several behaviours to avoid the risk. Corvids are among the most serious nest predators. However, they are also among the most neophobic of any birds.

Wildfire-Driven Shifts in Bird and Red Fox Activity: A Case Study from Biebrza National Park [PDF]
BiologyFires of natural or anthropogenic origin shape some ecosystems on Earth; this disturbance can maintain the landscape and influence many processes like vegetation structure, carbon, and hydrological cycle, climate, and others [...]

Opportunistic Tool Use by Two Unexpected Corvid Species [PDF]
Ecology and EvolutionThis Nature note reports the first documented instance of tool use in Sunda crows (Corvus enca) and provides additional evidence of this ability in house crows (Corvus splendens).

Tiny but mighty: Insects can drive carrion decomposition in the absence of facultative vertebrate scavengers. [PDF]
EcologyAbstract Scavengers play a key role in recycling animal biomass, yet the relative contributions of insects and vertebrates to this process remain poorly understood. Moreover, understanding whether one scavenger group can compensate for the absence of another is critical for predicting how carrion decomposition may respond to changes in community ...

Prevalence and Toxoplasma gondii Genotypes Circulating in Five Wild Corvid Species from Romania [PDF]
PathogensThe apicomplexan parasite Toxoplasma gondii can potentially infect all warm-blooded animals, including birds, which, due to their high dispersal capabilities, are considered a significant candidate group of sentinel animals that reveal environmental ...
