Some birds just don't like to be seen, and one such bird is the Orchard Oriole. There could indeed be a confusion between a girl Summer Tanager and a girl Orchard Oriole. But probably more important is why persist. Why risk physical injury creeping around trying to see someone who doesn't want to be seen, then coming away with "It could have been a female Orchard Oriole."
The other thing thing to recall, is that being able to say "Yes it was a female
Orchard Oriole" and then nodding wisely is central to the self image of a
pompous ass. So clearly your correspondent is very far from being cured of that
odious condition, he's got a long way to go, he's pretty much in the nappy phase
of recovery. All the same, there's someone that could be an Orchard Oriole who
could be thinking about nesting in the vicinity, they have really neat nests and
that's all I'm going to say about most of yesterday.
