Hi Jim,
I think what Tim and I are asking, from you or someone else, is what is the official position of eBird reviewers/MD record keepers, hybrid or otherwise? There is a lot of inconsistency, and right now in eBird it appears that if you saw the bird before March 1, you saw a Trumpeter, but after that, you saw something undefinable.
I am no expert on hybrids, but I think a lot of us who use eBird try to keep the data quality high, as it is a valuable citizen science tool. So we would like to enter the bird consistent with what the official record is.
The purpose of having reviewers at all is to make judgments on issues such as this.
While, certainly, some birds will remain inscrutable, telling people to enter essentially whatever they want is a bit frustrating.
I very much appreciate all the time and effort that reviewers volunteer to eBird and other official records. eBird is revolutionary, and a fantastic resource, I think we are just looking for a bit more clarity on this particular bird.
Thanks
Chris Tonra
