Numbers of shorebirds have arrived at Swan Harbor Farms.  Highlights from my 45 minute walk:
 
Green-winged Teal - 125
Gadwall - 6
Great Blue Heron - 1
Northern Harrier - 1
Greater Yellowlegs - 5
Dunlin - 2, I've never seen Dunlin in March in Harford before.  I was a bit surprised to not see Pectorals.
Wilson's Snipe - 35+ I suspect more, but they move around too much for an accurate count. 
Tree Swallow - 15, several inspecting nest boxes along the road.
Savannah Sparrow - 6
 
There were 2 Horned Grebes at Lapidum this morning.  The Bonies were all distant and north of Port Deposit.  I've been checking 2-3 times a week all month and no odd gulls yet.
