I saw only six species of warblers at the National Arboretum this 
morning, but one was a life bird - a MOURNING WARBLER. The Mourning 
Warbler was on the southeast side of the Mt. Hamilton / Azalea Gardens 
area, where two trails diverge to go up the south side of the hill. It 
perched in one of the azalea bushes, and later walked around on the 
ground until it disappeared from view. The GRAY-CHEEKED THRUSH was on 
the main gravel trail between the Mt Hamilton parking lot and the Azalea 
Gardens.

One odd thing I noticed was an Acadian Flycatcher that seemed to be 
beating its wings against its body to create a "wing-whir" noise similar 
to a Mourning Dove. It was not doing that in flight - it would do it 
while sitting on a branch.

Here's the rest of my sightings:

Green Heron
Osprey
Yellow-billed Cuckoo
Eastern Wood-Pewee
Acadian Flycatcher

Good birding,
