311 eggs at true relative size, from the 16.9 mm egg of the Araucaria Tit-Spinetail to the 35.9 mm egg of the Great Rufous Woodcreeper.
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).
2,118 of them are marked Speculative: we haven't found documented descriptions or measurements of these eggs yet (for 129 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.
