I have sent the question off to Sheri Williamson, so hopefully we will have a
definitive answer soon. Hopefully the second edition of her hummingbirds guide
will be out later this year.

Thanks for posting that one Jim, great photo. First off it is a bit
frustrating trying to gather info on the primary pattern for all possible ages
and sexes of the common hummers in NA. Adult and juvie males, adult and juvie
females. Sheri Williamson's site covers many points but it is hard to figure
out if adult male Rufous has the same pattern as say a juvie female Rufous.
Anyway, this bird seems to have evenly wide primaries right down to P9, P10 is
hidden. Rufous, I think, have noticeably narrower P9s. Anna's have very short
secondary coverts, this bird has its coverts covered by that scapular, very
short. Anna's and Broad-tailed both have evenly wide primaries right to the
P9. SO is that wing an Anna's or a combo Anna's Broad-tailed. The loral area
does not look good to me for a pure Selasphorus, no loral crescent that I can
see. So I am thinking it has some Anna;'s in it along with a Selasphorus.
Rufous by location, but I cannot eliminate a Broad-tailed.
Love to be corrected on my errors or if I have messed up on my feather tract
id..

With Bob Archer’s prompting, I added the photo that I sent him last night
showing the backside of this bird and the wing pattern. Here’s the eBird link
again: https://ebird.org/checklist/S92327263
If this is an pure immature female Rufous Hummingbird, it certainly is outside
the norm. The sides are much paler than a typical Rufous and there is some
green showing through. The large, red central spot on the throat would
certainly be atypical for a female immature Rufous as well. I’ll try for some
more shots of the tail spread if the clouds lift. It is still guarding the
same feeder as yesterday and running off immature male and female Rufous as
well as Anna’s hummers.
Cheers,

I was going with Rufous at the start. Then Jim sent me an in focus shot of the
folded wing, it shows very short secondary coverts. This is an Anna's trait
Sheri Williamson points out on her hybrid page.

I agree with Tom, but a month or so ago I had a similar experience with a
hummer at my feeder. Not so much the species ID, although that threw me off
for awhile.but also the overall appearance/demeanor of the hummer. Mine was
around for several weeks. ...to be continued.............eventually.if I get
organized.

Jim,
I’m not seeing anything here that would make me suspect anything other than an
immature female Rufous Hummingbird. The tail pattern as shown in your last
photo shows a green central tail feather (R1). R2 through R5 show significant
amounts of rufous and a broad black subterminal band. R1 would not be green on
an immature male. Broad-tail is the only other hummer (except Allen’s) that
has significant amounts of rufous in the tail. Calliope can show a little wash
of rufous, but not the extent that this bird shows. Female Black-chinned,
Anna’s and Costa’s have no rufous. This bird is immature as evidenced by the
clean, not worn feather edges.
Allen’s can be ruled out by range (there are no records for Allen’s away from
the coast in Oregon and only one east of the Sierra’s in Northern California.
Besides, females are inseparable in the field so in order to prove it was an
Allen’s it would have to be captured or collected. Unfortunately general field
guides aren’t particularly helpful on non-standard plumaged birds. Consulting
Howell's "’Hummingbirds of North America: The Photographic Guide” and Sheri
Williamson’s “Peterson Field Guides Hummingbirds of North America” indicate
that the amount of rufous on the gorget is highly variable. The only thing odd
I see about this bird is the paleness of the sides. The structure looks good
for Rufous (big headed, barrel chested, long-tailed) and nothing suggests
Anna’s or hybrid to me.

COBOLanders and OBOLanders,
This morning while enjoying coffee and birds on the upper deck, Kim and I
noticed a hummingbird that seemed odd compared with the usual Rufous and Anna’s
that usually come into the feeder. The obvious marking that set it off from
the others was the greenish/peachy sides rather than the green/gray of an
Anna’s or the orange of a rufous. We also noticed a central red patch on the
gorget. This bird dominated and defended the feeder, which allowed me to take
several photos in poor light conditions. I’ve posted these on the eBird link
below.
Please take a look and tell us what you think. Is it a hybrid?
https://ebird.org/checklist/S92327263
I’ll attempt more photos of the tail pattern if it is still around.
Cheers,
Jim
