Blue jays are coming back to MN to mate & nest. They are extremely noisy. They have several different calls, including a call that mimics a Red-shouldered hawk. This call is used to warn other birds of the presence of a hawk or other raptor. Blue jays nest in April or May, & have 4-6 speckled eggs that can be pink, green, blue, or olive. Both male & female look after the young, until they leave at 3 weeks. The female can have several broods in a season. Blue Jays are monogamous – they mate for life. Blue Jays are known for stealing & eating other birds young, but in a study, only 1 percent of the birds did this.
