Golden Eagles in the United States of America: Threats and the Federal Response to Potential Impacts from Renewable-Energy Development

Пернатые хищники и их охрана, 2023
Golden Eagles (Aquila chrysaetos) have a Holarctic distribution. The subspecies A. ch. сanadensis inhabits North America, where it encounters the same anthropogenic threats as other eagle species worldwide, including electrocution on powerlines, shooting,

Bald eagle (Haliaeetus leucocephalus) population increases in Placentia Bay, Newfoundland: evidence for habitat saturation?

Avian Conservation and Ecology, 2015
Across North America, Bald Eagle (Haliaeetus leucocephalus) populations appear to be recovering following bans of DDT. A limited number of studies from across North America have recorded a surplus of nonbreeding adult Bald Eagles in dense populations ...

Optimal Cluster Head Selection in WSN with Convolutional Neural Network-Based Energy Level Prediction

Sensors, 2022
Currently, analysts in a variety of nations have developed various WSN clustering protocols. The major characteristic is the Low Energy Adaptive Clustering Hierarchy (LEACH), which attained the objective of energy balance by sporadically varying the ...

Poleward Range Shifts of Breeding Birds in Wisconsin. [PDF]

Ecol Evol
Anthropogenic climate change has been documented to cause poleward range shifts in birds. This paper uses Wisconsin's two Breeding Bird Atlases to determine climate change's impact on the ranges of birds in the state. We found that warm‐adapted birds in the state were expanding northward.

Confirmation that eagle fatalities can be reduced by automated curtailment of wind turbines

Ecological Solutions and Evidence, 2022
Automated curtailment is potentially a powerful technique to reduce collision mortality of wildlife with wind turbines. Previously, we used a before–after–control–impact framework to demonstrate that eagle fatalities declined after automated curtailment ...

Soil moisture content prediction model for tea plantations based on SVM optimised by the bald eagle search algorithm

Cognitive Computation and Systems, 2021
In order to solve the problem of low accuracy and efficiency of soil moisture content prediction in tea plantations and improve the level of soil water content prediction, a soil moisture content prediction model for tea plantations based on the support ...

Anticoagulant rodenticide exposure and toxicosis in bald eagles (Haliaeetus leucocephalus) and golden eagles (Aquila chrysaetos) in the United States.

PLoS ONE, 2021
Raptors, including eagles, are geographically widespread and sit atop the food chain, thereby serving an important role in maintaining ecosystem balance.

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.
