The northwest winds this past weekend provided a welcome tailwind and therefore led to a big flight of southbound Monarch butterflies. Tim Dyson had a HUGE one-day Monarch total with 48 seen on Saturday (Sept. 6). His 2014 Monarch total now stands at 140. I counted at least 10 Monarchs on Saturday and another eight on Sunday.
Warblers and vireos were also on the move. On the Peterborough Field Naturalist Sunday Morning Bird Walk, we were able to find Nashville Warbler, Wilson’s Warbler, Black-throated Green Warbler and Red-eyed Vireo. Other observers found even more migrants, especially Ian Sturdee. Click on “Checklist” under his Bay-breasted Warbler sighting below.
