Eggs

87 eggs at true relative size, from the 12.8 mm egg of the Orange-cheeked Waxbill to the 26 mm egg of the Pine Grosbeak.

About this collection. 4,422 eggs, covering nearly every bird that nests in the Americas, from Canada and the United States through Mexico, Central America and the Caribbean to South America, plus a few famous eggs from elsewhere, like the Ostrich and the extinct Elephant Bird. Sizes come from published measurements wherever we found them; shapes and colours are our best estimates (how accurate these eggs are).

2,147 of them are marked Speculative: we haven't found documented descriptions or measurements of these eggs yet (for 133 of them, a source we checked reports the egg as undescribed), so they are estimated from their closest relatives. They are hidden unless you untick Hide speculative eggs. We keep adding sources and update the eggs as we go. Have you seen one of these eggs, or know a source? Message us.
