Which red tanager (Denver)?

[JaredD]

During a morning walk without binoculars, I encountered an unfamiliar call (see recording). Eventually, the all red tanager making the call flew over me, but I didn't get good enough views to ID by sight. Both Scarlet and Summer Tanagers are rare here. Thoughts on which I've recorded?

I'd say this is a pretty solid contender for a Summer Tanager. I just heard one making this call on Saturday.

It's definitely a rarity for Denver, but one has been sighted in Parker a few weeks ago: https://ebird.org/checklist/S149474551

If I heard that here, where they are common, I would have no question it is a Summer rather than a Scarlet. I have no experience with tanagers of the western US, but listening to the calls of Western and Hepatic neither sound close.

That definitely sounds like Maryland Summer Tanagers.

Thanks all! This was indeed consensus among others I consulted, including Merlin (who I tricked into making an ID by changing the location of the encounter). It was also pointed out to me that a Scarlet Tanager right now wouldn't be as brilliantly red as a Summer...and perhaps not red at all.
