Buff- breasted sandpiper
Continues today, Friday, at Robb Field. Early in the day it was south of the tennis courts, but left that area in favor of the westernmost ball field. However it is spending most of its time out in the pickleweed north of that ball field, flying to the grass periodically, then back out to the river channel.
A bird does not sing because it has an answer. It sings because it has a song.
