Winter Experiences Carry Over into Swallows’ Breeding Success
There’s no shortage of studies demonstrating that conditions during one part of birds’ annual of breeding and migration cycle can affect individuals in subsequent stages — a phenomenon known as carry-over effects.
Do Prairie-Chickens Care More About Land Cover or Wind Turbine Noise?
Imagine living in a grassland landscape with an almost constant low-frequency hum from spinning wind turbine blades. The humming is distracting, so what do you do?
Songbirds Indicate Short-Term Restoration Success
To understand the impact of restoration efforts, one of the things we can do is study the wildlife that lives in these human-restored habitats.
A Vacation Like No Other
Back in the 1980s, one of my graduate students and I split the cost of an Ontario Lottery ticket. We knew that the chances of winning were vanishingly small (p<0.000001) but the jackpot had risen to $24 million—real money in those days. It was a cheap and fun investment that could really help my research …
Researchers Identify Previously Unknown Hybrid Zone Between Hummingbird Species
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, …
