Friday on the Hot Eastern Shore

So, I’ll confess:  I really wasn’t going lepping on the Eastern Shore yesterday.  In actuality, I was going down to Salisbury Airport to twitch for the large numbers (comparatively) of Upland Sandpipers being seen on the the grassy areas between the tarmac runways.  In vain, as it happens — Uppies would be a life bird for me, but I’ve dipped every time the past couple of years I’ve gone hunting them.  Yesterday was no exception.

But before the disappointment of the late afternoon in Salisbury, I stopped off at a couple usually productive sites to see what leps were out and about in the heat.

First stop was just across the Bay Bridge at Terrapin Park, which you can actually see off to your left as you come across the bridge onto the Eastern Shore.  There are a few salt marshes there, one of which has a nice perimeter trail with a few blooming swamp milkweeds, and that’s where all the action was: especially the hordes of Broad-winged Skippers.  A Delaware Skipper was the coolest find of the batch.

I finished with a walk around the meadow area, but the blazing sun sent me on my way after about another hour and I moved on down Route 50 to the Chesapeake Bay Environmental Center in Grasonville, known to many seasoned naturalists by its old name of Horsehead Farm.  At CBEC  the activity was right around the Visitor Center, especially on the ornamentals in the butterfly garden.  One thistle plant at pond’s edge right off the education center veranda held a number of small skippers, including what apparently was a country record Southern Broken-dash.

Last lep stop was a drive through a couple of normally very productive areas around Blackwater National Wildlife Refuge:  Key Wallace Drive, the Wildlife Drive, Bestpitch, and Shorter’s Wharf Road  But it was pretty much a dead zone — no nectar sources, the roadsides have been mowed first and now drought stricken.  Bone dry.

All this brought me to the Salisbury Airport at around 6:30 pm, where I sat on the picnic tables near the visitor lot and looked vainly through bins and a spotting scope for about 2 hours until dark fell, much to the evident concern of the Homeland Security types!
