Migrating birds speed up in spring

It turns out being the early bird really does have its advantages. A new study in The Auk: Ornithological Advances shows that migrating birds fly faster and put more effort into staying on course in spring than in fall, racing to arrive to their breeding grounds as soon as possible to get an edge in raising the next generation.

Migrating birds travel faster in spring than in fall because arriving late to their breeding grounds can affect their reproductive success. Past studies have shown that migrants take shorter breaks in spring, but it’s harder to tell whether they also move faster in the air.
