I post this unofficial bird report only to echo Bill Hubick's claim
that Smith Island, MD is an incredibly fun place.  I was there this
weekend on a kayak trip, and below is the list I chalked up without
really focusing much attention on birds.  With better optics and more
time, it might be twice as long.

Brown pelican (colony of hundreds on South Point Marsh)
Double-crested cormorant
American oystercatcher
Semipalmated plover
Least sandpiper
Great egret
Great blue heron
Green heron
Yellow-crowned night heron (juvenile, in Ewell)
Little blue heron (juvenile, on Goat Island)
Tricolored heron (on Swan Island)
Mute swan
Canada goose
Red-breasted nuthatch
White-breasted nuthatch
Brown creeper
Golden-crowned kinglet
Yellow-rumped warbler
Pine warbler
Eastern phoebe
Eastern kingbird
Northern flicker (yellow-shafted)
Terns
Gulls
Grackles
Starlings
Sparrows

Butterflies were everywhere, coinciding with lots of types of flowers
in bloom (I wonder what kind of climate Smith Island has to produce
Rhododendrons in October?).  In droves were MONARCH, COMMON BUCKEYE,
and RED ADMIRAL, with an occasional GRAY HAIRSTREAK.  I saw several
fluttering in the distance that glowed chartreuse, somewhere between
yellow and neon green, but I never got close enough to identify them.
Many large dragonflies buzzed around too, but again, I didn't get
close.

A few photos of the swarms of pelicans and butterflies are
interspersed in my trip report here:

For those with the time and means (namely a kayak and GPS), one of the
places I'd recommend is Martin NWR north of Smith Island.  It vast,
uninhabited territory holds huge promise for birding.  I only spent an
hour or two there, and can't wait to go back to explore in depth.
