Eastern Bluebirds

Eastern Bluebirds are laying eggs!
After the female lays the last egg, incubation begins for 11-19 days. The female builds the nest and the male brings her the material to weave. Nesting averages 20 days. Bluebirds have multiple broods each year and there is a 1 in 5 chance that one egg is fertilized by another male. Oops!
