Inter‐ and intra‐individual variation in the feather coloration of American crows
Journal of Avian Biology, Volume 2026, Issue 2, March 2026.Avian feathers are remarkably diverse in both form and function. Coloration is among the most studied feature of feathers, but we know relatively little about melanin‐based black coloration. Despite many crows (Corvus sp.) and other corvids having black feathers that appear uniform to human perception, their feather coloration could play an important ...

Managing nesting by Chihuahuan ravens on H‐frame electric transmission structures
Wildlife Society Bulletin, 2012 Electric utility structures occur widely in natural and human‐dominated landscapes and are often used by birds for nesting. Nests can cause power outages, fires, and electrocution of birds and their young, particularly if nests occur directly above ...

Communicative & Integrative Biology, 2016 In recent years, we have investigated the possibility that Eurasian jay food sharing might rely on desire-state attribution. The female's desire for a particular type of food can be decreased by sating her on it (specific satiety) and the food sharing ...

Peck or pass? Individual‐level testing of a bird‐repellent seed coating
Pest Management Science, Volume 82, Issue 3, Page 2333-2339, March 2026.Using sequential unique‐choice tests on an urban population of ringed carrion crows, we show that black pepper oleoresin‐treated maize seeds were avoided, while color alone had no deterrent effect. Abstract Background Carrion crows (Corvus corone) are a major depredating species of spring crops across European agroecosystems, especially during sowing ...

Evaluation of drones as a tool for multi‐species nest surveys on linear rights‐of‐way
Wildlife Society Bulletin, Volume 50, Issue 1, March 2026.This paper examines the use of drones with infrared cameras as a tool in the detection of bird nests on linear rights‐of‐way, in comparison to standard ground‐based nest surveys. Abstract The varying application of drone use in wildlife research has expanded in recent years. With the ability to utilize a variety of different sensors (e.g., infrared [IR]

Assays to Detect West Nile Virus in Dead Birds
Emerging Infectious Diseases, 2005 Using oral swab samples to detect West Nile virus in dead birds, we compared the Rapid Analyte Measurement Platform (RAMP) assay with VecTest and real-time reverse-transcriptase–polymerase chain reaction. The sensitivities of RAMP and VecTest for testing

Gastrointestinal Helminths of Magpies (Pica), Rooks (Corvus Frugilegus) and Carrion Crows (Corvus Corone) in Mazandaran Province, North of Iran [PDF]
Iranian Journal of Parasitology, 2011 Background: Corvidae is a cosmopolitan family of oscine birds including crows, rooks, magpies, jays, chough, and ravens. These birds are migratory species, especially in the shortage of foods, so they can act like vectors for a wide range of ...
