without repeating the previous messages--

another factor that may be confusing the issue is migration timing, as
we've seen quite well this year. The eastern mountains are possibly two or
three months behind the western lowlands. While birds on the westside have
been on territory for weeks, the birds on the eastside are still moving
through. The danger is to think that the two should be similar.

We can find Orange-crowned Warblers in the lower elevations around
Wenatchee in early June. I always assumed that they nested here, partly on
the belief that most Orange-crowned Warblers would be on their breeding
grounds by early June.

The two races should also be distinctive enough to separate in the field.
Have to think about them.
