[mou] Sherburne NWR, Blue Hill Trail

[Pastor Al Schirmacher]

Eleven warblers (Wilson's and Black-throated Green were new migrants), 
probable Yellow-bellied Flycatcher (visual only) this morning at Blue Hill 
Trail, Sherburne NWR.

Interestingly, double-digit (10-13 species) warblers have been consistent 
daily in both Sherburne & Mille Lacs Counties (refuge or state parks) since 
early last week.

Good birding to all!
