Colorful dyed eggs<\/a> typically grab the spotlight on Easter, but the world of bird<\/a> eggs is so much bigger than chickens. There are as many colors and sizes as there are bird species. According to conservation writer Paul Baicich, the co-author of Nests, Eggs and Nestlings of North American Birds<\/em><\/a>, there is a reason some eggs are white and some are colored<\/a>.<\/p>\n White eggs in the wild mostly belong to the birds that nest in deep holes in trees or terrain. These birds are called cavity nesters and the contrast between the white egg and dark spaces help them see their eggs. Some cavity nesters include woodpeckers, owls, and kestrels.<\/p>\n Wild colored eggs\u2014not the ones the Easter Bunny hides\u2014generally belong to birds that nest in more open areas on the ground. This color makes them more difficult to find.\u00a0 Because eggs in ground nests have color, they are harder for predators to find. Plovers, gulls, and most ducks are considered ground nesters.<\/p>\n Take a peek into this exciting world in the gallery below. (Click to expand images to full screen.)<\/em><\/p>\n
