I visited the Hatfield Marine Science Center, Newport today and saw the suspect
Orchard Oriole. I have posted several pictures to Oregon Birding Association
Photos Facebook. At Portland Audubon Birder's night yesterday, there were
discussions about the size of the bird and how to get a measurement. I took
pictures of a blackbird at the feeder with hopes of getting the oriole also. It
cooperated and you can see clearly that the oriole is smaller (length) than the
blackbird. Bullocks should be longer. You can also measure the birds vs the
length of the base of the feeder to confirm. I'm not an expert, so I'll leave
the ID to you folks.
