Hi Gun smoke, Link below is to a site that gives a good account of whats seen in north america. Will help with ebird too, has a specie list by state/province. using with Ebird will help pin it down. Maybe stretch the odds towards catching a glance.

After you have your species by state list...
Then give Ebird.org a whirl, once there choose, "explore data", "range and point maps"... then enter particular specie and your location. Checking "show quicker" will show graphic flags with data on map.
Quick look showed records of Rufous this past march around Chaple hill and elsewhere. Looks like theres a few records for Anna's sporadically, last about two years ago. Having so much coast stacks the odds in favor of exotics blowing in occasionally too. Let you dig for those rascals.
