Field Trip: Saturday, September 03, 2011

Trip Leader: Smith, Dick

Date of Trip: Saturday, September 03, 2011

Location: Butterflies through Binoculars:
Elkhorn Garden Plot

Details: Trip was to continue to path along poweline south of Oakland Mills Road. Note that it was pretty much overcast during the walk (starting at 9:30 a.m.), and then we decided to end early (around 10:30 – 11:00 a.m.) because of a threatening thundershower at first, and then no apparent letup in the clouds.

Number on trip: 17

Birds: Bald Eagle.
Well, it was billed as a butterfly trip...

More details: Some of the attendees were wondering what butterflies really were there and that we might have seen if the weather had been better, and so I returned and re-surveyed between 2:15 and 3:45 p.m when the sun was out. Actually, I covered three sites, with letter codes as follows:
