16 warblers still present on Blue Hill Trail, Sherburne NWR this morning - plus a Lawrence's backcross that was also heard/seen during Saturday's field trip - however, numbers of birds had begun to diminish a bit, and only two Yellow-rumpeds were present.
One of the Mournings was finally back on territory. Late Horned Grebe on back pond. Good birding to all! Al Schirmacher Princeton, MN Mille Lacs & Sherburne Counties
