Corvids create novel causal interventions after all [PDF]
Proceedings of the Royal Society B: Biological Sciences, 2015 Using a novel paradigm, Tayloret al.[1] recently investigated whether NewCaledonian crows make causal interventions in comparison to 24-month-oldchildren. They view a causal intervention as the ability, after having onlyobserved a correlation between cause and effect, to produce a novel behaviouralpattern to recreate the same outcome.

Ibis, EarlyView.Artificial breeding structures, such as nestboxes, can potentially influence the population size and conservation status of bird species relying on heavily human‐modified environments such as agroecosystems and urban areas. However, the effectiveness of these interventions may vary, as artificial structures could attract individuals to suboptimal ...

Dickens, Grip and the Corvid Family
Caliban: French Journal of English Studies, 2020 Dickens loved animals, birds and flowers, and kept many pets: dogs, cats, and at one period of his life, ravens. This article is concerned with these latter, in the context of the crow family (Corvidae) to which they belong.

Journal of Anatomy, EarlyView.Psittaciformes exhibit high levels of morphological diversity, particularly in skull and beak structure, previously linked to diet and body size. Although there were some levels of significance between diet and beak shape, body mass was a much stronger co‐variate. Diet is not determining beak shape within the clade.

Testing nest deterrents for Chihuahuan ravens on H‐frame transmission structures
Wildlife Society Bulletin, 2015 Chihuahuan ravens (Corvus cryptoleucus) regularly perch and nest on electric utility structures. Because ravens perch on overhead shield wires, for which no perch discourager exists, management focuses on nests.

Medical and Veterinary Entomology, EarlyView.A study of louse flies in the United Kingdom, Isle of Man, and Ireland found 212 different interactions between Hippoboscidae and their hosts, of which 70 were previously unrecorded. No louse flies were found on aquatic species of birds. Host‐switching to gulls (Laridae) has occurred during a period in which these species have started relying on ...

CORVID SURVEY TECHNIQUES AND THE RELATIONSHIP BETWEEN CORVID RELATIVE ABUNDANCE AND NEST PREDATION
Journal of Field Ornithology, 2001 Abstract We conducted a four-year study on the Olympic Peninsula of Washington to assess the relationship between corvid (Gray Jay [Perisoreus canadensis], Steller's Jay [Cyanocitta stelleri], American Crow [Corvus brachyrhynchos] and Common Raven [Corvus corax]) abundance and the risk of nest predation. We assessed risk of predation through the use of

Ecological Applications, Volume 36, Issue 2, March 2026.Abstract European forests are increasingly managed to harmonize production goals with biodiversity conservation, through practices such as retention and close‐to‐nature forestry. Forest birds may benefit from these practices, but it remains unclear how the effects of different management practices compare, and whether responses to management are driven

Functional morphology and integration of corvid skulls – a 3D geometric morphometric approach
Frontiers in Zoology, 2009 Background Sympatric corvid species have evolved differences in nesting, habitat choice, diet and foraging. Differences in the frequency with which corvid species use their repertoire of feeding techniques is expected to covary with bill-shape and with ...
