After having nothing to report, and expecting more of the same this morning,
I was startled to find several migrants, including two of the rarest warblers
found in the park. A Prothonotary Warbler popped up for a few seconds at
point blank range, and disappeared just as abruptly. It was either the second
or third ever for me in 36 years birding this park. The next surprise was a
singing Orange-crowned Warbler that was buried in the thick foliage and flowers
of a Black Cherry for a good 10 minutes before moving out in the open. That
was #5 that I know of in the same 36 years.
In the face of northeast winds, it seems unlikely that these birds migrated
here last night, but I guess it's possible. Another scenario that I have
suspected for a long time is that these birds dropped into the Potomac Valley some
time ago and worked their way northward up Watts Branch. This being the end
of the line, they accumulate here, as Watts Branch arises on the King Farm,
now a mass of condos a few hundred yards north.
