*Rare but not unexpected migrant. Heard distinctive burry musical calls west of the park and saw two large-bodied swallows with well-notched tails, dark breasts and pale bellies flying low over the treetops. Got a couple of bad documentary phone recordings that hopefully captured a few calls; will upload when I get home (in a few weeks). Ran to my car to get the parabola but no further calling.
