About

Everybird turns any birder's life list into a sticker collage.

What it is

Your life list is already a record of every bird you've seen. Everybird lays it out as one collage: every species a sticker, sized by its body mass, with the count in the middle. Filter it by group, place or year, then share it as an image or a link.

An animation of Everybird at work: an eBird export file is dropped onto Settings, under Your sources, and its rows are read. Then the collage builds, stickers arriving around the count as it rolls up to 197 species. Choosing the Herons filter brings the six herons into the middle; All birds, in the breadcrumb, brings everyone back. Share makes the image to post: the birder's name, the stickers around 197 species, the latest lifer and the sticker credit.
  1. Bring your list on Settings: an eBird file, an iNaturalist username, or birds ticked by hand. Combine them if you keep more than one record.
  2. Each bird is matched to this year's eBird taxonomy and keeps its earliest date. Rows that don't match are listed, so nothing is dropped quietly.
  3. The collage, the filters and the share images are all made in your browser.

Your list never leaves your browser. We count visits anonymously, without cookies.

What True size means

Each sticker is sized from the bird's average body mass, from AVONET. The default evens sizes out: the long side follows mass to the power of 0.2, so small birds stay visible next to big ones.

True size uses the cube root of mass instead. Birds are roughly similar in density, so mass tracks volume, and its cube root tracks length: a bird eight times heavier is drawn about twice as long. It's an estimate of relative size, not a measured length, so birds with long tails or legs read a little small.
