The development of multiplex STR panels for the identification of bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos)

Forensic Science International: Animals and Environments, 2023
The ability to reliably genotype individual bald eagle (Haliaeetus leucocephalus) and golden eagle (Aquila chrysaetos) samples has proven to be a valuable forensic tool for investigations of illegal trafficking of eagle feathers and body parts.

Mitochondrial Genome Analysis of Philippine Eagles (<i>Pithecophaga jefferyi</i> Ogilvie-Grant 1896) From the Greater Mindanao Faunal Region. [PDF]

Ecol Evol
Mitogenome sequencing is a promising alternative for the genetic studies of animals. In this work, we examined the genetic diversity of the critically endangered and endemic Philippine eagles and their evolutionary relationship to other birds of prey.

An Open‐Door Policy: How Removal of a Visual Barrier Improved Welfare in Zoo‐Housed Bald Eagles (Haliaeetus leucocephalus) [PDF]

Zoo Biology
Birds of prey are renowned for their excellent visual acuity, but they are often not given visual access consistent with their natural behavior when housed under managed care.

Lead Intoxication in Free-Ranging Bald Eagles (Haliaeetus leucocephalus) [PDF]

Veterinary Pathology, 2018
Lead toxicity due to ingestion of spent ammunition is an ongoing cause of mortality in bald eagles. While gross and histologic lesions of lead intoxication have been described in a few individuals of this species, the prevalence of lesions is underreported. A retrospective study of 93 bald eagles with severe lead intoxication was performed to describe

Cryptocotyle lingua INFECTION IN A BALD EAGLE (Haliaeetus leucocephalus) [PDF]

Journal of Wildlife Diseases, 1978
Approximately 11,000 heterophyid trematodes, Crytocotyle lingua, were recovered from the small intestine of a bald eagle, Haliaeetus leucocephalus, in Nova Scotia. Severe emaciation of the eagle was attributed to the heavy burden of trematodes. The wide distribution of this trematode in the Maritime area and the fact that fish are a primary source of ...

Increased Mortality Rates Caused by Highly Pathogenic Avian Influenza Virus in a Migratory Raptor. [PDF]

Ecol Evol
We utilized movement data to identify a continental‐scale mortality event caused by highly pathogenic avian influenza virus (HPAIV) in a single species of migratory bird, the rough‐legged hawk (Buteo lagopus). We estimated an HPAIV cause‐specific annual mortality rate of 28% that substantially elevated the overall annual mortality rate (47%) above ...

Examining the Effectiveness of Automated Acoustic Recording Units for Recording Predator-Related Disturbances in Colony Nesting Birds: A Case Study. [PDF]

Ecol Evol
Automated recording units (ARUs) have soared in popularity within the field of avian research and have been used in various studies to replace human observers when collecting data. There is, however, a lack of research into the actual reliability of ARUs when compared to in‐person observers, especially when investigating avian behavior. This case study

Electrochemotherapy Intralesional Treatment in a Captive Peregrine Falcon (Falco peregrinus) with Dermal Squamous Cell Carcinoma [PDF]

Animals
Captive birds of prey often exceed their wild counterparts’ lifespan, as seen in bald eagles (Haliaeetus leucocephalus, ~20 years wild vs. ~40 years captive), golden eagles (Aquila chrysaetos, ~32 years wild vs.
