Bill,

Very cool morning flight photos. Like missiles frozen in time by the 
camera. I have to go down and see this for myself sometime.

I recorded for nocturnal migrants on 5/15-16 despite northerly wind 
direction. Conditions very calm though. I had a decent amount of "zeep" 
type warbler calls but very few thrush calls. Maybe 10 thrush in six 
plus hours. All Swainson's - no Gray-cheeked or Veery. Its a bit late 
for Wood. Maybe the warblers are a little more desperate (sorry for the 
anthropomorphizing) at this point than the thrushes to get to where they 
need to be.

Possibly birds flying on a night w/ a calm NW wind direction (it was NE 
here in G'burg by morning) get pushed slightly off the coast setting up 
good conditions for a spring morning flight at Bayside?

By stating "The best part about doing spring morning flight, when there 
is one, is that the flyovers are WAY easier to work with than in fall," 
is this due to adult birds being in prime breeding colors and no juveniles?

There's no doubt that we picked a perfect day to do it! The strange weather produced a noteworthy fallout of migrants on Assateague, and we ended the day with 167 or so species, 28 species of warbler, and 20 species of shorebird. To ensure I get this out tonight, here are just the highlights:

The best part about doing spring morning flight, when there is one, is that the flyovers are WAY easier to work with than in fall. This was easily the most enjoyable couple hours of birding we'd seen in the state. Here's the migrant list from Bayside. Note the high numbers for several species, as well as the number of rare-on-Assateague species such as Summer Tanager and Hooded Warbler. The 19 BLACKBURNIANs and seven adult male BAY-BREASTED were excellent. Our only complaint is that the GOLDEN-WINGED WARBLER posed only long enough for Jim Brighton to get a good look. All counts are certainly lower than actual numbers due to obvious detection challenges.

White-rumped Sandpipers were seen during each of three visits this weekend. A Stilt Sandpiper was present on Friday. Saltmarsh Sparrows are easily scoped, even heard singing, at the end of the road in the early morning.
