If you need help identifying bird eggs this guide offers useful tips. 

Robin egg blue
Most of us would recognize the robin’s egg anyway. Robin egg blue is so familiar that it is a Crayola™ crayon name. The robin is a gray, black and red bird that lays a blue egg. The bluebird’s egg is white. A cardinal egg is brown-speckled. A goldfinch lays a pearl-white egg, so the clue is not a connection to the bird’s color. The color usually gives a clue though. A killdeer lays its eggs on the gravel, so it is speckled with brown on white to camouflage it.

Where were the bird eggs found?
The type of nest, or lack thereof, the position and location of the egg can help you determine the type of bird. Many more birds than you may think build a nest on the ground, like the swallows (Lincoln’s, Savannah, Grasshopper, Seaside, Henslow’s, White-Throated, Bachman’s, Lark, Vesper and Song sparrows). Chuck-Will’s Widow, the Whippoorwill, Common Nighthawk, the Meadowlark, the Bobolink and the Killdeer lay their eggs in the leaves or gravel. Some build nests only in conifer trees, some only in oaks or in shrubs or tree hollows. The cliff swallow makes a nest in sandy cliffs. Water birds nest near waterways, rivers, lakes, ponds, streams and swamps.
