Bob,

Thanks for your compilation but I'm puzzled as to what this means. What do you infer from this?

Tropical Kingbirds can normally be separated from Western Kingbirds by visual field marks. An exception might be worn Western Kingbirds that don't show much if any white edging on their tails -- but then you would hope to see a note on the bill size, as well as general tail, back and breast color, if the observer thinks it's a Tropical Kingbird.

There are two separate questions that have come up recently here on OBOL:

1) Has there been past confusion over Couch's vs.Tropical Kingbirds?

2) Has there been past confusion over Cassin's Kingbirds vs. late fall Western Kingbirds?

We've already beaten the former dead horse well past death. The latter question might still be relevant but I don't see how it hinges upon vocalizations.

Well, many of the Tropical Kingbird observations have been accepted by the Oregon Birds Record Committee, which later removed TRKI from the review list.
Here are all the records available from OBRC online. I have indicated the observations that reported silent birds in bold to the right.
Previously I stated that my report of hearing the calls in Nov '86 at Nehalem Meadows was not accepted by OBRC I DID get a letter to that effect. But, as Jeff Gilligan told me decades later, it WAS indeed accepted and appears in the list below. Now there are quite a few birds reported as silent and one could perhaps
infer that the others reported the calls? Note that most of the later reports did mention 'silent' .but not the earlier ones.
Of course, this is just a listing of accepted reports. The actual reports will contain the details, which could have discussed the vocalization situation.
Interestingly, the 13 Oct 1998 observation of Western Kingbird in this thread almost coincides with the 11 Oct 1998 report of a
silent Tropical on Grand Island and the 6 Nov 1982 Western in this thread coincides with the protracted observations of TRKI at Newport. (both bold italics below) The first report of TRKI in Oregon in 1970 does not appear in this listing. Perhaps Harry didn't send it in to OBRC, or perhaps OBRC did not exist way back then? It's never too late, Harry...............

Considering that there's no way to ever prove what they were, OK, Jeff, you're on!

I'll bet my entire personal fortune of East German Marks, Finnish Marks, and Dutch Guilder that they were in fact Western Kingbirds. Might even throw in a few Soviet-era Rubles :-)

I bet that they were Tropical Kingbirds, or maybe even one was a Cassin’s.

Roy makes a good point regarding observer expectations.

However the three mid/late Oct and early Nov reports of Western Kingbirds mentioned in BOGR were from 13 Oct 1998 , 18 Oct 1985 , and 6 Nov 1982. So all of these were a dozen or more years after Harry Nehls found that Tropical Kingbird in 1970, back when Nixon was still the one. So one hopes that Oregon birders would have considered TRKI as a possibility for those birds.
