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.

Seabird population responses after the removal of an introduced predator
The Journal of Wildlife Management, Volume 90, Issue 7, September 2026.We studied the response of a breeding population of seabirds (pigeon guillemots) to the removal of an introduced population of predators (American mink) from an archipelago that was formerly the largest aggregation of nesting guillemots in Prince William Sound, Alaska.

Veterinary Medicine and Science, Volume 12, Issue 5, September 2026.We developed sensitive real‐time PCR assays for West Nile virus and Usutu virus to screen bird and human samples in Finland. Although no positive samples were detected, active migratory flyways and recent cases in neighbouring countries highlight the risk of future introduction and the need for continued surveillance.

Nestling provisioning rate was influenced by an interaction between NND and corvid abundance.
, 2015 Points show raw data with corvid abundance split into above and below median values (corvid abundance is categorized in the graph for ease of visualization but designated as a continuous variable in the model). Lines are predicted from the final averaged

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
