Egg Collection Posters

About the Egg Collection Poster app

Make your own poster of bird eggs at true relative size. Pick the eggs, give the poster a title, and the app lays them out on the smallest standard print size that fits them well, as large as fits (up to twice life size). Tick Life size to keep the eggs at their real size instead. The scale is printed under the title, and the key lists every egg's length and width. Your download includes two matching 300 dpi posters: one with grey silhouettes (as in the preview) and one with illustrated, coloured eggs.

Egg shapes. Each outline is drawn with the same egg-shape model as the SaviMade Egg Generator, set to the species' average length and width and its typical end shape, so the outlines match the 3D-printable eggs exactly.

Egg sizes. Mostly from A. C. Bent's and C. Bendire's Life Histories of North American Birds (averages of measured museum eggs), with the Cornell Lab's All About Birds and other published sources where Bent has no average. The sources used for your eggs are listed in the poster's footer. Sizes marked * are approximate.

Egg colours and markings (for the illustrated posters) are drawn from published egg descriptions, mainly the Cornell Lab's.

Using your poster. Your poster is yours to use however you like: print it, frame it, give it away, share it online, use it in teaching or sell prints of it. Unlike the 3D models in the Savi Made shop, it isn't limited to personal use. The one condition is that the footer text must stay on the poster exactly as it is: readable, and not cropped, covered or edited. It credits the app, the illustrations and the sources of the egg sizes.
