I did, indeed, hear part of a wren's song, and the call of the sandpiper; but that was all.
After the eagle had passed the sandpiper resumed his feeding.
Curiously enough the Sandpiper is not aquatic in its habits.
It had no tail, but it wagged the hind end of its body just as a sandpiper does.
It is a very similar bird to the Least Sandpiper, and about the same size.
