64. Cyanocitta cristata. Blue jay. — Michigan: Abundant resi- 

 dent, breeding throughout the state. 



This species was a rare breeder in this region, and was very rarely 

 seen or heard. It was reported to be more common in winter.

 in southern portion; breeds throughout the state. 



Abundant throughout the sand region and on Stony Island. It 

 was an abundant breeder, and many nests were found in the jack
