Hi all --

Well I give up.  I still cannot figure why today was the day when so many 
birds chose to move - not noticably warmer than recent days and no 
overnight rain to ground the birds.  But at 6.30am when I went out onto the 
deck with a cuppa tea the trees around the house were hopping with Yellow-
rumps (FOS from the house) and there was a nice Black & White too.

I joined Greg Butcher and a some other folk to do the Arboretum and it was a 
great morning.  Rarely have I seen so many birds grounded in DC - granted a 
large proportion were Yellow rumps but there was plenty to keep us diverted 
even so. 

It sounds like we saw pretty much the same as Rock Creek only numerically 
more birds and I think Cape May was the only notable species of warbler 
difference.

We spent from 8-11am in the Azalea garden and then spent a short time on 
Hickey Hill area.

Warblers (12 species):
Blue-winged - 1
Black-throated Green - 8
Black-and-White - 10
Hooded - 1, singing male
Ovenbird - 6
Palm - 1
Parula -- 20
Yellow-rumped (Myrtle) -- very many 150++
Magnolia - 3
Cape May - 1 singing and showing well
Pine - 1 (Hickey Hill)
Yellow -1 

and no Yellowthroats for us either!

Other migrants:
Wood Thrush - 6+
Gray Catbird - 8
Scarlet Tanager - 4
Orchard Oriole - 1, by the visitors center
Red-eyed Vireo - 6
Blue-headed Vireo - 3
Ruby-crowned Kinglet - 4
Blue-gray Gnatcatcher - 6 (including a pair nest building)
Cedar Waxwing - 10
House Wren - 2
White-throated Sparrow - 30
Chipping Sparrow - 60+ (seemingly everywhere)
Field Sparrow - 2 
Rose-breasted Grosbeak - 2
Indigo Bunting - 8
Brown Thrasher - 4
Phoebe - 1

Also lots of Goldfinches Blue Jays flying over.

Wat fun!

Best
