Subject: [Va-bird] Great Falls NP Bird Walk 09/10/2017 (Fairfax County)
Following is the tally from Sunday's weekly bird walk at Great Falls National Park, which identified approximately 38 species. 
One of the highlights of the walk involved several noted instances, both downstream and upstream, of what appeared to be large clouds of mist rising above the Potomac River.  Upon closer observation, however, the clouds actually were immense swarms of flying insects, highlighted in the rays of the morning sun.
The walk meets on Sunday mornings at 8:00 a.m. in front of the snack bar/concession stand of the Great Falls Park visitors' center.  All birders are welcome!
