Led a youth tour along Blue Hill Trail yesterday, highlights included both the previously reported Hooded and a Cerulean Warbler (seen by Paul Lender/note his MNBird post, and my son, Nathan - naturally the guide missed it!). If one enjoys hybrids, there was a Brewster's in the front, open part of trail (two note call) - and a Lawrence's (bizarre 5-7 note call, beginning with the emphatic buzz) on the back side, just after one clears the coniferous woods.
Also had an unexpected Sanderling (county bird) working the shore of the St. Francis River where it intersects with CR 5 (2-3 miles north of the CR 5 & 9 intersection). Good birding to all! Al Schirmacher Princeton, MN Mille Lacs & Sherburne Counties
