Hello, my name is Mike. I'm a first time poster. I've been birding since April of 2019. I've been struggling with the ID on this bird, and am now reaching out for help in this message board. Sorry, for the poor picture (It's the reason I'm having a hard time). The picture was taken on September 12th in Perth County, Ontario. I originally thought it was a Pine Warbler. Now I'm leaning more towards a Blackpoll Warbler. Let me know what you think. Thanks.
