观察细节
A bird at the base of the cattails was repeated giving a twittering call similar to that given by a Bald Eagle. I recorded it, and at Skye Haas's suggestion, compared it to the call of a young Virginia Rail. It was a good match for a recording in Cornell's Macaulay Library of Natural Sound which can be heard as the second recording by Bob McGuire (catalog number ML 233281) at https://search.macaulaylibrary.org/catalog?taxonCode=virrai&mediaType=a&q=Virginia%20Rail%20-%20Rallus%20limicola&age=j. My submarginal recording is attached for comparison/documentation.
