Migration shapes patterns of disease transmission

Long-distance animal migrations can trigger relapse of dormant infections, influencing when and where infection risk peaks, according to a new paper in Proceedings of the Royal Society B. The findings demonstrate that relapse ...

Rare pattern observed in migrating common swifts

Compared with other migratory birds, the common swift follows a very unusual pattern when it migrates from the breeding areas in Europe to its wintering locations south of the Sahara. This is what researchers have observed ...

American robins now migrate 12 days earlier than in 1994

Every spring, American robins migrate north from all over the U.S. and Mexico, flying up to 250 miles a day to reach their breeding grounds in Canada and Alaska. There, they spend the short summer in a mad rush to find a ...

Fifty years of data show new changes in bird migration

A growing body of research shows that birds' spring migration has been getting earlier and earlier in recent decades. New research from The Auk: Ornithological Advances on Black-throated Blue Warblers, a common songbird that ...

Predicting 50,000 years of bird migrations

Neither wind, nor rain—nor massive sheets of ice—have kept Earth's birds from their appointed rounds of migrating to better climes, according to a new study.

Bird migration timing skewed by climate, new research finds

Life cycles for birds, insects and trees are shifting in this current era of a rapidly changing climate. How migration patterns, in particular, are changing and whether birds can track climate change is an open question.

Changing climate is narrowing options for migrating birds

Across an entire desert or ocean, migratory birds make some of the most extreme journeys found in nature, but there are still huge gaps in our understanding of how they manage to travel these vast distances and what a changing ...

Evolution is resetting the annual clock in migratory birds

The timing of spring migration is vital for birds. Returning too late comes at a cost. In 1981, German ornithologist Eberhard Gwinner demonstrated how an internal circannual clock is responsible for the correct timing of ...
