What is the ratio of Audubons to Myrtles when YELLOW-RUMPED
WARBLERS pass though the Northwest on migration?

When a horde of YELLOW-RUMPS swept through the Nisqually NWR
on April 16, I picked out 3 dozen or so individuals to watch for a time
each. Roughly half were Audubons and half Myrtles.

(The 3 dozen individuals that I spied upon seemed only a small
part of the whole rustling wave of Yellow-rumps that picked their way
through the foliage that morning--which is why I called it a "horde.")
