["Jon Little" <littlejon@xxxxxxxxxxxx>]

As intriguing as this trail is to me, I'm more interested in knowing which bird 
built the nest first noted by Mary - Robin or
Cardinal?

According to the reference that Paul noted, a Robin will use a nest built by a 
Cardinal, but does it work the other way too?

Because it's easy to tell the difference of these nests by their structure, I'm 
curious whether this assessment was or can be made.
And as John mentioned, has a photo or video been taken of it?

Regardless of the explanation, any rare occurrence like this is a real treat 
for an old nest hunter like myself. I wish I'd been
there!
