Eurasian tree sparrow.
We drove 3 hours to see an Eurasian tree sparrow at Niagara on the Lake at the mouth of the Niagara River. It is a rare visitor to Canada. There is a small population near St. Louis, Missouri. Identifying field marks include, black throat and ear patch. White cheeks and a rufous crown. About 5 minutes after we arrived at the house it had been seen at, it flew in with a large number of house sparrows. Not a great shot but it was away from the road in a private yard. Passer montanus
