The Common Nightingale, known for its beautiful song, breeds in Europe and parts of Asia and migrates to sub-Saharan Africa every winter.
Populations of some common bird species, including the familiar Mourning Dove, have been on the decline for decades in North America.
New research shows that fall migration patterns have been shifting over time.
In the Pacific Northwest, the range expansion of Barred Owls has already contributed to a conservation crisis for Northern Spotted Owls.
If you’re a predator that eats baby birds — say, an American Crow — eavesdropping on the begging calls of nestlings can be an easy way to find your next meal.
Reproduction and migration are the two most demanding tasks in a bird’s life, and the vast majority of species separate them into different times of the year.
We usually think of a species as being reproductively isolated – that is, not mating with other species in the wild. Occasionally, however, closely related species do interbreed. New research just published in The Auk: Ornithological Advances documents the existence of a previously undiscovered hybrid zone along the coast of northern California and southern Oregon, …
Animals that do well in urban areas tend to be the ones that learn to make use of resources such as the food humans throw away. But is our food actually good for them? A new study published in The Condor: Ornithological Applications suggests that a diet of human foods such as discarded cheeseburgers might …
When the Northern Spotted Owl was protected under the Endangered Species Act in 1990, the primary threat to the species was the loss of the old-growth forest it depends on. However, new research published in The Condor: Ornithological Applications shows that the Northern Spotted Owl population in Washington’s Mount Rainier National Park has declined sharply in the …
