Eastern Bluebird (Sialia sialis) nest with eggs. Notice how neatly woven the nest is, and it’s made entirely from grasses, which is something to look for when you’re identifying a bluebird nest. They will always nest in a cavity. This is a second brood, so the clutch size is smaller than the usual four or five eggs. Eastern bluebird eggs are typically pale to medium blue, although they can sometimes be white.
