Eggs of the Blue Jay are either blue or pale brown with brown speckles. These eggs range from 1 to 1.3 inches in length and require approximately 18 days to hatch.
Common in both urban and forested locations, blue jays construct their nests 10 to 25 feet above the ground in crooks or thick branches of deciduous or coniferous trees. Male and female birds both engage in nest construction, with males mostly acquiring nesting materials and females constructing the actual nests. Once hatched, Blue Jay chicks are born blind and without feathers. Before fledging, they remain in the nest for 17 to 21 days.
