Scarlet Tanager

I was not surprised when eBird flagged this first-year, male Scarlet Tanager as being rare in Minnesota on 12 October. The record is close, but before, the latest dates in the state listed by Janssen.

I have previously posted a note on the molt sequence of male Scarlet Tanagers. I have seen first-year, male Scarlet Tanagers a few times in the fall in Minnesota, and once, years ago, during the winter in the Amazon jungle of Ecuador. According to Mowbray (1999), most Scarlet Tanagers arrive in Columbia by mid-October and Ecuador and Bolivia by November. Little or nothing is known about the speed of their migration or how weather affects their travels.
