Chestnut-sided Warbler - North Vancouver, BC

This little visitor is definitely a ways from home. The multi-colored warbler is usually no farther east than Saskatchewan/North Dakota during breeding season but does have some occurrences here. The BC Rare Bird Alert mentions that this is the 70th record for this province. I find it interesting that the 68th and 69th records were within a couple weeks of this bird with one of the sightings just across the inlet in Vancouver on Jun 22, 2018. Was there a short circuit in a flock of birds that was headed up from Central America? No matter, This bird was a first for me in Canada
