Responding to Don Baccus's remarks:
Lazuli Buntings breed at the Sandy River Delta and at scattered
locations around the remaining habitat about the Portland Airport and on
Powell Butte where they even are featured on the interpretive sign
there. Yellow-breasted Chats also breed at the Sandy River Delta and at
Scoggins Vally park in Washington County. These areas are all either in
Portland or close to the city limits. Just this June I observed both
Chats and Lazuli Buntings at the mouth of the Sandy River.
For what its worth,
