I am generally confused about how to log this bird. I find it nice, even with birds like this that a likely escaped, to see the eBird report for the sighting. I've never seen one so it was nice to have the report and go down to Brookline to see it. I found this website which give a little info: https://aba.org/birding/v43n5p46.pdf
Also, for those who are interested, eBird says, "Escaped or introduced species should be reported, but will count on your lists. In the future we plan to give the option to selectively remove obvious escapees from selected lists." http://help.ebird.org/customer/portal/articles/973921-what-data-are-appropriate-
