Last June, I got an e-mail from a couple in Port Orchard who said they
had three Northern Cardinals in their yard. These must be the same
people mentioned by Ken Brown. (They sent photos, but I couldn't open
them on my computer, so I can't confirm the identification.) I told
them that these birds almost certainly were escaped cage birds, but
encouraged them to report them to the WBRC, so the sighting would be
part of the official record. I wouldn't expect their report to be
accepted, but, as Doug Schonewald says, it can be revisited if a pattern
of vagrancy ever starts to emerge.

It doesn't sound like these people ever made a report. I will forward
all of these Tweeters posts to them, in case they would like to send one
in now.
