Song diversity hints at thrushes' evolutionary past

The Hermit Thrush is famous for its melodiously undulating song, but we know very little about whether its songs vary across the large swath of North America that it calls home in the summer. A new study from "The Auk" provides the first thorough overview of geographic variation in Hermit Thrush song structure and hints at how isolation and adaptation shape differences in the tunes of a learned song within a species.

It's World Oceans Day. Tell Canada to Protect Them.

Canada should keep its 10 per cent marine protection promise

Happy World Oceans Day!
Dear Larry, 
I’ve loved oceans my whole life. So I’m watching as world leaders gather in New York this week to discuss how to conserve and sustainably use them.
Canada’s government is starting to take action on its 10 per cent marine protection commitment. But with less than one per cent protected, there’s still a long way to go.
Please encourage the federal government to meet its targets while creating high-quality protection for orcas, belugas, salmon, puffins and more. Send your letter to government now.
