In years when winter conditions are especially harsh, birds that depend on conifer seeds for food are sometimes forced to leave their homes in northern forests and wander far from their normal ranges to find enough to eat. A new study published in The Auk: Ornithological Advances uses citizen science data to show for the first time …
Scientists who want to study the evolution of behavior face a fundamental problem: unlike bones, behavior generally doesn’t fossilize. However, that doesn’t mean that extinct species’ behavior doesn’t leave any evidence. The behavior of living or “extant” species can give us clues about the behavior of their ancestors, and we can use the behavior of living species, the evolutionary relationships among species, and computational modelling to make inferences about extinct species’ behavior.
Like many people, I am fascinated by bird flight. Unlike most people, I get to study flight of Golden Eagles for a living. These large birds move through the landscape primarily by soaring—a style of flying where they hold their wings outward and rarely flap, saving them considerable energy. Instead of flapping, they rely on rising air currents to gain altitude.
Where should we draw the line between species? Biologists have debated this question for over 100 years. For much of that time, Ernst Mayr’s Biological Species Concept, which defines a species as a group of individuals that is reproductively isolated from other groups, has dominated the conversation. Recently, however, more and more evidence of hybridization between species has accumulated, especially in birds.
In the summers of 1966 and 1967, I worked (Dream Job #2) for Bill Carrick at the Niska Waterfowl Research Station near Guelph, Ontario. Bill was an outstanding wildlife cinematographer and a superb naturalist who was director/manager of that facility. My job was to raise and feed the myriad birds and mammals that he used …
A number of birds that use forests disturbed by timber harvest have been declining for decades in North America’s Pacific Northwest.
Most of the ornithologists that I know have a great sense of humour. My old friend and mentor, James L. Baillie often took me birding when I was a teenager and his typical response when I could not identify a big, distant bird was “You know the crow?”. At first, he was almost always right …
CELEBRATING THE HISTORY OF WOMEN IN ORNITHOLOGY Until the 1970s, few women could have called themselves ‘professional’ ornithologists no matter how great their contribution to the study of birds. As I have documented earlier in this series of essays about the history of ornithology, women were most often (i) invisible, in the sense that we …
The American Ornithological Society is committed to providing professional development opportunities for our members. With that in mind, if you’re a faculty member and are invited to review a paper for The Auk or The Condor, we encourage you to consider involving graduate students you mentor in the peer review process. If you have an advanced graduate student who …
CELEBRATING THE HISTORY OF WOMEN IN ORNITHOLOGY In one of my earliest memories—I must have been about 6 years old—it is summer and I am sitting in my grandfather’s garden as his seven hens and a rooster forage around me, almost within touch. I am watching them closely, giving each of them personalities, figuring out …
