I looked in my three bird books and online and still can't determine if this is some kind of immature oriole or some other bird? Any help would be appreciated. I live in southern Maine, if that helps. I have seen this bird more than once over the last 1-2 weeks. I have seen a female and a few male orioles and none look like this one. Thanks in advance.
FYI, it has been a good week for birding the yard. Indigo bunting, scarlet tanager, orioles, magnolia warbler have all stopped by, in addtion to the regulars.
