A free bird migration map for your website
Put a live migration map on your site: watch a bird spread across the country week by week, zoom to your state, and press play to see the whole year. Pick a bird, copy one snippet, paste it into any page.
It is made for Audubon chapters, nature centres, bird clubs, schools, bloggers and local newsrooms. It is free, with no sign-up, no ads, no cookies and no tracking of your visitors. The maps are drawn from millions of birders' checklists (2016–2025) and are updated whenever we refresh the data.
Paste it where your site takes HTML (in WordPress, a Custom HTML block; in Squarespace or Wix, an embed or code block). Keep the line under the map: it lets your readers find the full species page.

Common questions
- Is the migration map really free?
- Yes. Any site may embed it, commercial or not, with no sign-up and no fee. Please keep the credit line inside the map and the link under it.
- Does the map track my visitors?
- No. It sets no cookies, runs no analytics or ads, and loads nothing from other companies. It only fetches the map data from WhenToBird.
- Will it slow my page down?
- The frame loads lazily, and the map starts only when it scrolls into view. Browsers without WebGL get a plain county map instead.
- Which birds can I show?
- Any of the species with a WhenToBird map: type a name in the Bird box. You can start the map zoomed to one state, pick a light or dark theme, and have it play the year on load.
- Where does the data come from?
- From complete birding checklists. Each county is shaded by the share of checklists that reported the bird that week. Our methods page lists the sources and explains the details.
