The Harris's Sparrow is something of a novelty to birders in southern Ontario where the species is very rarely seen. According to Alan Wormington, the species is a regular autumn migrant from Marathon westwards.
Yesterday, two were found in Marathon. One was (and remains) in our yard in the company of a loose flock of 100+ sparrows (White-crowned, White-throated, Chipping, Clay-colored & Lincoln's). Our friend Nolan also found one in his yard. Gary Emms reported another, a beautifully marked adult, at his feeder in Longlac.

Update: Sept 23
The juvenile, present at our feeder since September 19, was joined today by a more boldly marked adult.
