I thought one of yesterday’s posts or maybe this morning mentioned that the bird was heard. No?

Fortunately kingbirds tend to be noisy. Many of the ones I have seen in Oregon talked, especially on sunny days.

Some variation in shape of the P4 on adult males, and other subtle in-hand features can separate them but otherwise they must be recorded as Tropical/Couch’s until vocals can confirm species. Current eBird records of this Newport bird make no mention of calls and the records should be changed to the dreaded ‘slash’.

I've seen quite a few fall Kingbirds, but only one of them ever vocalized, and it gave the typical twitter of a Tropical. All the others have been silent. What experiences have others had in this regard?
