Finally, a graphical model shows that pirating frequency may or may not be influenced by changes in food abundance. The results generally support the predictions of game theory and explain several aspects of Bald Eagle foraging behavior. 展开 ...
Units of Measurement for Fractal Extent, Applied to the Coastal Distribution of Bald Eagle Nests in the Aleutian Islands, Alaska Attempts to measure the nesting density or territory size of bald eagles led to a fundamental difficulty, inherent in all such measurements on organisms which are distribu...
We explored changes in seasonal distribution and behavior of waterbirds in the Strait of Georgia, Canada, in response to increased presence of a major avian predator, the Bald Eagle (Haliaeetus leucocephalus). Eagles were widespread and their increase through fall and winter coincided wi...
"A lot of species we really care about became more abundant in human landscapes during the pandemic," Nicola Koper of the University of Manitobasaid. "I was blown away by how many species were affected by decreased traffic and activity during lockdowns." Bald eagle sightings increased in citi...

Bald eagles are capable of making biggest nests that can be 2.5 m (8.2 ft) wider, the depth of 4 meters (13 ft), and weighing about 1 metric ton (1.1 tons). Bald eagle facts also demonstrate the average age of these birds i.e. 20 years; however, the maximum age proceeds to 30 ...
like those seen in a juvenile bald eagle, requires careful arrangement of the environment and building skills with your bird to have more reinforceable behaviors. The workshop also highlighted the importance of fitness and motivation over strict weight control, ensuring the bird's health and well-...

In understanding the impacts of selective logging on biodiversity, relatively little is known about the critical behavioral link between altered forest con
