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 ...

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,

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 ...

Generational Habituation and Current Bald Eagle Populations

Human-Wildlife Interactions, 2017
Bald eagle (Haliaeetus leucocephalus) populations have expanded, even as increasing human presence and activity near nesting sites has increased. The generational habituation hypothesis may explain current bald eagle behaviors associated with human ...

Movement Models to Predict Low-Altitude Flight of Soaring Birds Using Look-Ahead Environmental Factors. [PDF]

Ecol Evol
Eagles see ahead. Now our model does too. By modeling how eagles respond to terrain and wind conditions in their line of sight, we can predict where they'll fly in the next 3 min with 3× better accuracy than current methods—protecting eagles while maximizing energy production.
