Project Update: Visualizing Migration

New Maps

This spring, we’ll be tracking migration from many angles. New interactive maps made with eBird data will give us a bird’s-eye view of migration in progress. For example, the following map tracks the northward progression of Tree Swallows in the last few weeks. Zoom in and have a look around!

Thanks to eBird, we can also track Martins on the move, as they push away from the Gulf Coast:

And Greater Yellowlegs as they make inroads in the center of the US.

Updated Charts

We’ll also make use of line graphs showing the percent of eBird checklists reporting species through time. Below, the black and white line shows the current year, while the colored lines show previous years. We can see that Eastern Phoebes are departing the southeast…

…and arriving in the Northeast & Upper Midwest — although their arrival has slowed in the last few days, perhaps due to recent cold weather.

Twitter

We’ll be providing frequent migration updates on Twitter this season, such as the ones below, so be sure to have a look at our page.
