NEWS RELEASE: For Rufous Hummingbirds, migration looks different depending on age and sex
CORVALLIS, Ore. – Plucky, beautiful and declining in numbers at about a 2% annual rate, the Rufous Hummingbird makes its long annual migration in different timing and route patterns based the birds’ age and sex, new research by Oregon State University shows. The findings, published in the journal Avian Conservation & Ecology, are important because the more that is known about how Rufous Hummingbirds migrate, the more that can be done to ensure birds of each age and sex category have the resources they need each year on their journey up and down the western part of North America.
