The rain began about 10 minutes after the group set out. Light at first, it soon became a steady downpour, but they remained out for about another hour. And not surprisingly because the birding was really good! Peter found all sorts of neat things including a scarlet tanager, a green heron, yellow warblers, rose-breasted grosbeak, white-crowned sparrows, etc.

Here is a list of birds submitted by Peter Fuller:

Ring-billed gull
Mallard
Great blue heron
Green heron
Red-tailed hawk (possibly, but too far too see well)
