Scouting Strategy: Know EXACTLY Where the Birds Are
For some of the tougher birds, it pays to stake them out during scout week as specifically as possible. This year, one of my worries was that the Canada Warblers would stop singing. I went into the Black Spruce Bog of High Point and slowly worked my way along the edge. I only heard the birds sing twice, but I found the edge where it appeared that two territories met. By studying the birds for 15-20 minutes, I found that they could be easily found by their chips, and responded well to imitations.
Here's a snap I took of one of the birds coming in to investigate the other pair of Canadas.
