Dear All

After the first warm night for some time and a bit of cloud I thought that it 
might be a good morning for a crop of new birds in Rock Creek, but alas it was 
not the case.  Despite the small number of birds the stalwart few plugged 
away for a couple of hours after dawn around the Nature Centre, Stables and 
Maintenance Yard and on reflection did accrue a nice list of common migrants -
a 12 warbler day can't be described as completely uneventful.

Warblers:  Yellow-rumped (40), Black & White (2), Parula (4), Hooded (1 seen 
and heard), Magnolia (1), Blackpoll (2), B t Blue (3), B t Green (5), 
Yellowthroat (2), Redstart (3 - none seen), Ovenbird (2 heard) plus a Yellow 
not seen by us.  

Other things:  Baltimore Oriole (10), Scarlet Tanager (1), Red-eyed Vireo (3), 
Wood Thrush (2), Swamp Sparrow (1), G C Flycathcer (3).

The next crop of migrants awaits...
