Yep, probably. And there are probably more males than you think, too! I would have bet money that we only had one pair of orioles last year. One day I set up the blind to get some pics, put out the grape jelly, and suddenly there were three
males queued up at the feeder!!!
And of course they all had their lady-loves, too.
This year we have over a dozen birds...they go through a 32 oz jar of jelly in less than 4 days, the gluttonous things!!!
