2nd round:  

14 Dec 2021 Acc Continuing to accept.
Mike H. 15 Nov 2021 To 2nd  

2nd round:  

27 Dec 2021 Acc There were a couple of things on this bird that I had concerns with when initially looking at the record. Admittedly, I wanted to spend more time on this observation than I had at the time so, I kicked the record to the second round to buy me more time.
Max M. 25 Oct 2021 Acc  

2nd round:  

27 Nov 2021 Acc Pretty straight forward juvi RTLO, and I was able to confirm ID myself. Continuing to accept.
Bryant O. 24 Oct 2021 Acc  

2nd round:  

8 Nov 2021 Acc Not sure what the concern is with this one? Only thing it could be confused with is a Pacific, but there were 2 Pacific also present giving direct comparisons, even in the same field of view of the scope. There is a striking difference in head and bill shape between the two species as well as throat pattern.
Mike S. 23 Nov 2021 Acc Photos and description confirm the ID.

2021-62 Chestnut-sided Warbler

Evaluator Date Vote Comment
Stephanie G. 26 Oct 2021 Acc Well darnit
Mike H. 3 Nov 2021 Acc  
Max M. 26 Oct 2021 Acc Too bad it was a window strike. . . 3rd Chestnut-sided this year?
Bryant O. 27 Oct 2021 Acc Photos leave no doubt on ID, no reason to believe it died elsewhere and was transported to that location, although a full frame view of the strike area might eliminate all doubt as they often leave a smudge on the glass
Mike S. 23 Nov 2021 Acc Definitive photo
Bryan S. 27 Oct 2021 Acc  
Mark S. 15 Nov 2021 Acc Photo is definitive.
David W. 26 Oct 2021 Acc Guess this isn't one to chase. Excellent, if somewhat sad, photo.
Kevin W. 2 Nov 2021 Acc Photos seem good for a female Chestnut-sided Warbler, including the white eye-ring, bright greenish back, and plain chest/belly.

 

2021-63 Mexican Duck

Evaluator Date Vote Comment
Stephanie G. 17 Nov 2021 Acc  

2nd round:  

22 Dec 2021 Acc continuing to accept. i think it's as 'pure" as one would expect for a utah record
Mike H. 13 Dec 2021 To 2nd I struggle with this bird. First, although I understand why we are reviewing it, it is not technically its own species. Second, research has shown the low percentage of a pure Mexican Duck being this far north.
Looking more towards what others think and may just go with the flow .

2nd round:  

27 Dec 2021 Acc I agree completely agree with Mike S s sentiment.
Max M. 4 Nov 2021 Acc  

2nd round:  

20 Dec 2021 Acc Continuing to accept
Bryant O. 2 Nov 2021 Acc About as good as it gets for a pure Mexican in the states

2nd round:  

20 Dec 2021 Acc I see no obvious indication of hybrid in this one
Mike S. 7 Dec 2021 Acc I think that almost all Mexican Duck records in Utah can be nit-picked to the point of arguing against the ID. I believe all of these records should be reviewed cautiously. However, I also believe that records shouldn't be dismissed based on the possibility of very subtle Mallard traits.

2nd round:  

29 Dec 2021 Acc I'm sure some individuals will continue to give us a headache, but this one looks solid.
Bryan S. 14 Dec 2021 To 2nd Overall it looks good, but in some light (specifically photo D) appears to have some green tint to the head feathers but it doesn't show in other photos. Curious to read comments from others
Mark S. 15 Nov 2021 Acc Excellent photos; checks all the boxes with no signs of being a hybrid.

2nd round:  

30 Dec 2021 Acc If we're looking for hypothetical genetic purity on this species, we'll never find it in Utah. This individual falls well into the non-hybrid area phenotypically.
David W. 9 Dec 2021 Acc As has been noted by Sibley, Fridell, and other birding greats, Mexican ducks in the US and even in Mexico are intergrades to various degrees. So it really is pointless to look for a "pure" Mexican duck in Utah. That being said, this bird has some good southern qualities:
-- there appear to be no curly tail feathers as found in male mallards
-- the area below the tail is not white
-- the dark on the head does not look very green
-- good contrast between head and body, although the breast looks more chestnut than the rest, suggesting some Mallard ancestry
-- nice yellow bill with no black gape spot (as on a Mottled duck)
-
I'm going to vote YES and see what the rest of you think.

2nd round:  

17 Dec 2021 Acc I don't know how it's possible, but I still think this guy made it over that beautiful wall.
Kevin W. 2 Nov 2021 Acc This looks like a good Mexican Duck to me. Dark undertail coverts, neck color contrasts with breast color, and lack of upturned tail feathers all show good in photos.

2nd round:  

21 Dec 2021 Acc Still think it looks like a Mexican Duck.

 

2021-64 Parasitic Jaeger

Evaluator Date Vote Comment
Stephanie G. 17 Nov 2021 No, ID sparse description, other jaeger species not effectively ruled out
Max M. 4 Nov 2021 No, ID Not enough here to eliminate similar Jaeger species
Bryant O. 2 Nov 2021 No, ID No attempt made to eliminate Long-tailed or Pomarine Jaeger. Parasitic are notably smaller than a California gull, I'm not convinced they didn't just see a juvenile California Gull. This was seen during the time that many people were there looking for the reported Prothonotary Warbler, strange no one else of the many there also reported a Jaeger.
Mike S. 7 Dec 2021 No, ID I'm actually not convinced that this description rules out a first-cycle California Gull. In addition, there is no mention of how other Jaeger species were eliminated.
Bryan S. 14 Dec 2021 No, ID Inadequate description and no attempt to differentiate from other jaeger species, plus only a 5 second view
Mark S. 15 Nov 2021 No, ID This was very likely a Parasitic Jaeger, but there are no photos, and the description is barely adequate to call it a jaeger, let alone distinguish which species it was, especially in juvenile plumage. Not enough to go on here.
David W. 7 Dec 2021 No, ID I appreciate the effort of the observer to submit this record to the Committee, but there is very little here by way of species- or even genus-specific information to evaluate. If someone on the Committee knows the observer, perhaps they could encourage him to submit some more (and more precise) field marks for our consideration. This submittal process is not always intuitive to a first time submitter.
Kevin W. 17 Nov 2021 No, ID This may have been a Parasitic Jaeger, but I don't think enough detail is given to rule out other more likely species (gulls).

  

2021-65 Scissor-tailed Flycatcher

Stephanie G. 17 Nov 2021 Acc  
Mike H. 3 Nov 2021 Acc Good documentation.
Max M. 4 Nov 2021 Acc  
Bryant O. 3 Nov 2021 Acc Well written record and photos leave no doubt
Mike S. 9 Dec 2021 Acc Photos show a Scissor-tailed Flycatcher.
Bryan S. 15 Dec 2021 Acc  
Mark S. 17 Nov 2021 Acc Scant description and poor photographs, but for such a distinctive species, they're good enough.
David W. 3 Nov 2021 Acc As the observer noted, this is a pretty unique bird in this part of the world.
Kevin W. 17 Nov 2021 Acc Photos are definitive.

 

2021-66 Parasitic Jaeger

Evaluator Date Vote Comment
Stephanie G. 17 Nov 2021 No, ID I dont know if we can narrow this one down to the species level safely

2nd round:  

22 Dec 2021 No, ID not at the species level
Mike H. 13 Dec 2021 No, ID I don t feel there is enough in the description or photos to eliminate other jaeger sp.

2nd round:  

21 Jan 2021 No, ID Still feel there isn t enough information.
Max M. 15 Nov 2021 No, ID I am kind of on the fence with this one. This could very easily be a Parasitic Jaeger, and the photos, although poor somewhat support the record, but I don't think other species have been adequately eliminated. Curious to see what other reviewers think.

2nd round:  

20 Dec 2021 No, ID I think DW may have accidentally accepted, but sticking with my original vote. Not enough in the record for definitive ID.
Keeli M.  2nd: 4 Jan 2022 No, ID  Not enough evidence to rule out other jaeger spp, pictures are no help.
Bryant O. 6 Nov 2021 To 2nd Observers lack of experience with Jaeger ID is a problem and they did not really touch on most of the necessary field marks to eliminate other Jaeger species, and made no real attempt to do so. Photos are of no help. However based on their description of the tail it probably was a Parasitic.

2nd round:  

20 Dec 2021 No, ID My concerns were echoed by others and I agree not good enough to eliminate all other Jaeger species
Mike S. 9 Dec 2021 No, ID This may have been a Parasitic Jaeger, but the limited written documentation and very poor photos leave me unconvinced.

2nd round:  

29 Dec 2021 No, ID Looks like we're all on the same page.
Bryan S. 15 Dec 2021 No, ID I don't think the description eliminates other jaegers and pictures are not worth a lot
Mark S. 17 Nov 2021 No, ID We must be running a special on jaegers with indistinct, functionally useless photographs. Unfortunately, this record also lacks enough written description, and the observer enough experience, to determine the species here. Given the trend this year, Parasitic would be a good guess, but I can't make that call based upon the evidence presented.

2nd round:  

30 Dec 2021 No, ID Not enough here to establish i.d. to species.
David W. 7 Dec 2021 No, ID I don't think this report is specific enough to eliminate other jaegers. On an appreciative note, I did enjoy the treatment of gulls in the similar species portion: "Gulls, no." Many people feel that way about those rascal larids.

2nd round:  

17 Dec 2021 No, ID Nothing to add.
Kevin W. 17 Nov 2021 No, ID I'm not sure that the photos nor description are definitive enough.

2nd round:  

21 Dec 2021 No, ID Not a good enough description to rule out other species.

2021-69 Rusty Blackbird

Evaluator Date Vote Comment
Stephanie G. 17 Nov 2021 No, ID Sparse description with no mention of eye color
Mike H. 27 Dec 2021 No, ID Without photos, the description alone falls short of being able to ID this bird.
Max M. 27 Nov 2021 No, ID Eye ring? huh? Sorry - speechless on this one.
Bryant O. 17 Nov 2021 No, ID Eyering? Rusty can have a prominent supercilium and a dark line through the eye giving a masked look, but not an eyering as far as I know. No mention of rusty plumage on the back or wings, no mention of iris color, no mention of undertail coverts. Not sure what they saw, and based on this description we may never know.
Mike S. 15 Dec 2021 No, ID The description does not adequately rule out a drab nonbreeding Brewer's Blackbird, which would stand out in a flock of glossy black individuals. There is also no mention of the extent of rustiness, nor the level of dark contrast around the eye.
Bryan S. 14 Dec 2021 No, ID  
Mark S. 17 Nov 2021 No, ID Probably a good record, but not enough detail in the description to know.
David W. 7 Dec 2021 No, ID There is not enough here for me to evaluate. I am not sure what the observer means by "eyering." Perhaps he meant a pale iris. But even so, I would need more detail to get it down to species.
Kevin W. 20 Dec 2021 No, ID I don't think that there's enough information in this record to be sure it was a Rusty Blackbird. The only characteristics used to differentiate from a Brewer's were "slightly lighter plumage" and and "eyering"- which both seem odd field marks to note. Rusty Blackbirds don't really have an eyering, and plumage color can vary.

   

2021-70 Western Gull

Evaluator Date Vote Comment
Stephanie G. 14 Dec 2021 Acc I hemmed and hawed about this one due to the poor photos, but I can't see another species this could be.
Mike H. 27 Dec 2021 Acc  
Max M. 27 Nov 2021 Acc Poor photos, but excellent description rules out similar species. I still need to see one of these buggers in Utah. . . hope it sticks around this winter.
Bryant O. 17 Nov 2021 Acc  
Mike S. 29 Dec 2021 Acc I believe the written documentation eliminates similar species, and the blurry photos don't contradict the description.

The side-by-side comparison with HEGUs is especially helpful here, and I believe the combination of described field marks eliminates this species, as well as the others mentioned.
Bryan S. 14 Dec 2021 Acc  
Mark S. 12 Dec 2021 Acc Good documentation; the photos, though very poor, at least show two very good features for this species - the bulbous bill tip and the dark mask.
David W. 17 Dec 2021 Acc Detailed and convincing description. Nice writeup!
Kevin W. 21 Dec 2021 Acc The description and elimination of other gulls seems thorough. Photos could be more definitive, but do show a thick, droopy bill.

Mike H. 27 Dec 2021 Acc  
Max M. 27 Nov 2021 Acc Beautiful little bird. I've seen thousands of these buggers in the mid-west over the years (monitored 12-16 nests a year on the property I managed in Wisconsin from 2013-2017), but a Utah first for me. Given their success with 2nd story growth as a result of logging practices in the Midwest and increasing numbers, I wouldn't be surprised if they become a more regular visitor in UT.

2021-74 Snowy Owl

Evaluator Date Vote Comment
Stephanie G. 22 Dec 2021 No, ID did not eliminate similar species

2nd round:  

24 Jan 2022 No, ID Continued no. Did not eliminate similar species. Too much room for Mis-ID
Mike H. 27 Dec 2021 No, ID Although the observer may have very well seen a SNOW, I feel it s best to be very cautious with inexperienced birders reporting these without photo documentation. There have been too many erroneous reports of what are most likely Barn Owls. Also, when inexperienced it is very easy to convince yourself that what you saw in the field is what you re looking at online or in a field guide.

2nd round:  

21 Jan 2022 No, ID Still agree 100% with my initial thoughts.
Max M. 30 Dec 2021 No, ID I followed up with the record submitter via email, and he thought the "Snowy Owl" might nest above his house. . . Bryant, my dad and I investigated (given this seems like a reasonable location and an irruption year of sorts for SNOW) and the habitat was marginal at best, especially in the two locations that he reported to have seen the bird. I am not sure what you confuse a Snowy Owl with, maybe a Barn Owl, but personally I don't think there is enough here to accept.

2nd round:  

6 Jan 2022 No, ID Concerns echoed by others
Keeli M. 4 Jan 2022 To 2nd Description and location are consistent with snowy owl sighting but I hesitate to accept without photos.

2nd round:  

9 Jan 2022 No, ID Not evidence to rule out other species, not enough familiarity with observer to know level of experience, not enough supporting documentation.
Bryant O. 27 Dec 2021 No, ID Although the actual description of the bird does sound like a Snowy Owl, the incompletely filed out record raises a lot of red flags. No mention of their experience with IDing owls, no mention of similar species, no mention of the size of the bird etc, so I have no idea what experience level they have with raptors or owls. I wonder if there is a way we can make every field required to have at least something written in it before a record can be submitted? Again, records without physical evidence require a very thorough written description to eliminate all other similar species, this record falls short of that.

2nd round:  

10 Jan 2022 No, ID I've heard no argument for this being accepted, so I will continue my original opinion.
Kris P.   2nd: 11 Jan 2022 No, ID  Too many red flags.
- Observer acknowledges the level of rarity, but introduces the possibility that he may have seen a second one in the area.
- Distinct lack of any Snowy Owl reports west of the Rockies (in eBird) this winter with the exception of a few in Washington.
- Expression of 100% confidence. Confidence is not data, facts, truth or even falsehood. It's a belief based on some form of analysis and may not be supported by anything factual. I think this sighting was a remarkable experience for the observer, but falls into the category of seeing hoof prints and concluding it must be a zebra. I think it's more likely that this bird was a Barn Owl.
Mike S. 6 Jan 2022 No, ID I have several concerns with this record.
First, a 5-second view may not be enough time to eliminate a Barn Owl if you have no previous experience with this species. Second, no optical equipment was used. Third, we have no way of knowing whether other species were even considered since this section of the report form is blank. Fourth, some parts of this description (such as "speckled pattern") could be describing a Barn Owl.
All things considered, I don't think the documentation is sufficient to accept.

2nd round:  

10 Jan 2022 No, ID No changes of opinion...
Mark S. 30 Dec 2021 No, ID There are some things about the description that don't fit Snowy Owl. In particular, the speckled upperparts, especially the back of the head, would indicate an immature, but an immature wouldn't have an all-white belly. We aren't told whether the speckling is blackish, or brownish.

I don't think that we can completely eliminate the possibility that this was a Barn Owl from this description. It's also odd that such a distinctive bird was never re-found.
David W. 27 Dec 2021 No, ID Although this 5 second sighting might indeed have been of a Snowy owl, the record is too vague for me to vote to accept. There is no description of structure which would differentiate this bird from a variety of pale raptors or other leucistic/pale owls (Google, for example, "pale Great horned owl" and see birds matching this description). Hopefully the bird will return and the observer will get a photo or at least a third opportunity at recording some more field marks. Certainly, the reported habitat is appropriate for this species.

2nd round:  

7 Jan 2022 No, ID I still think that there is insufficient evidence in this record to vote to accept.
Kevin W. 30 Dec 2021 No, ID When I talk to normal (not birding) people about owls; many of them have seen pale-looking owls that they think must have been snowy owls. I need more than this observer's confidence to accept it.

2nd round:  

3 Feb 2022 No, ID I still don't think there's enough her to accept as a Snowy Owl record.

 

 2021-75 Purple Gallinule

Evaluator Date Vote Comment
Stephanie G. 24 Jan 2022 Acc I'm actually going to accept this record. The size and shape seems to be on point from what I can tell. I think juv coot has been effectively eliminated with the report.

2nd round:

7 Feb 2021 No, ID In light of others comments I'm changing my vote to no. Too much doubt has been cast with behavior, distance, and lack of other observations.
Max M. 30 Dec 2021 No, ID Bryant and I followed up on this bird the day after it was initially reported as a Common Gallinule. There was one oddly colored juvenile American Coot in the group of coots at the exact location, with some of the same plumage characteristics visible in the photos. With difficult distance and lighting conditions, I am having a hard time with this one. Would like to see other reviewers thoughts.

2nd round:

9 Feb 2021 No, ID Concerns unchanged.

Keeli M. 2nd:

8 Feb 2021 No, ID Really thorough write-up, so bravo for that. I don't believe the evidence lends enough support for Purple Gallinule or for ruling out Common Gallinule. That white stripe really throws me off the PUGA ID.
Bryant O. 31 Dec 2021 No, ID Angie is one of my Community Science volunteers and I've always been impressed by her precision due to her medical science background, and kudos to her for doing such a good job on this record, so many records lack good details these days. Nevertheless I'm not convinced this actually was a Purple Gallinule. Admittedly I chased their eBird report (of a Common Gallinule) and only found one weird looking immature coot mixed in with the raft of coots they described, from the same viewing location they described. We were there later in the afternoon the same day when the angle of the sun offered better viewing yet we still struggled with the young coot due to the distance. I think the distance and the angle of the sun at noon (note zenith would be at around 1:30pm due to daylight savings time) meant that their viewing circumstances would have been much worse. Young coots can have a yellowish bill and do have much more white on the UTC than adults, and because of their "teenage awkwardness" behave different than adults. Also immature PUGA don't acquire purple underwings until almost mature when they have a messy purple belly, I'm not sure that wasn't just an illusion of light in the scope? Is it possible they saw a bird that we didn't see later in the afternoon? Yes, but never the less I just don't feel immature coot has been completely eliminated as a possibility, much less Common Gallinule. Photos are pretty inconclusive but do seem to show a knob on the forehead that would favor Coot. I admit I have little experience with immature PUGA so could be wrong.

On a tangent, Common Gallinule has all but disappeared from Utah and even in the St. George area has shown a sever decline, most recent records are "audibles" which could actually be Coots. It might be a good idea to add Common Gallinule to the review list too? I would say their current status in Utah is unknown and obscured by mis-identification, which would seem to warrant review to clarify.

2nd round:

3 Feb 2022 No, ID It sounds like most of us have concerns about the distance and lighting circumstances. Also the point of PUGA not likely to be swimming seems to raise an additional red flag. With such an out of range vagrant I feel the burden of proof has not been meet for this record.
Kris P. 8 Jan 2022 No, ID The level of analysis and earnestness of the submitter is really commendable, but such a distant sighting in poor lighting conditions caused observed/photographed details to change. The poor images (although likely the best that could be captured under the circumstances) were further undermined by the narrative frequently qualifying that the actual observation showed something else. While I couldn't conclude that this bird was a Purple Gallinule, I also couldn't conclude that it wasn't.

2nd round:

6 Feb 2022 No, ID Multiple comments noting the bird's atypical behavior of swimming in the open further bolsters the conclusion that this was not a Purple Gallinule.
Mike S.  2nd: 31 Jan 2022 No, ID I spent a few days pondering this record and had my first round comment ready to submit, but then apparently forgot. So are my thoughts:

I commend the observer for this lengthy write-up. I can imagine a good amount of time must have gone into this, and the details provided are quite substantive.

However, I do have concerns about the distance observed, harsh light, and unusual behavior for a Purple Gallinule (swimming in open water away from any vegetative cover). I m not seeing enough detail in any of these photos to be confident about the ID, and I don't believe the most likely possibility (an immature American Coot) can be ruled out. The extensive white undertail coverts would be consistent with a PUGA, but coots can also show lots of white when swimming with their tail in an upright position. I'm not sure what to make of the "purple underwings," but again wonder about the reliability of this given the distance observed and harsh lighting conditions. All things considered, I believe there is too much uncertainty to accept.
Mark S. 30 Dec 2021 No, ID Well, I hate to do this to my successor, and I appreciate all the work the observer put into analyzing this record, but I don't think that the conditions of the observation, nor the quality of the photos are sufficient to unequivocally support the i.d. of this bird as a Purple Gallinule. Much is made of the purple underwings as a diagnostic feature, but even adult PUGA don't have purple underwings, so I have to conclude that this observation was a trick of the light.

If the bird was an adult the identification would be straightforward. Juvenile PUGA are a much warmer brown/fawn color than the photos show, even taking into account the tough lighting. The bird in question is not much different in color than the adjacent AMCO.

The tail shape/posture/whiteness is the strongest point in favor of PUGA over COGA, but even that doesn't rise to the level of "diagnostic" in either the photos or the description, given that COGA can exhibit similar enough features to be confusing under such difficult observational conditions. The posture regarding the wings that is presented as a potentially distinctive feature is also too similar in both species to be of much help here.

Part of the problem is the fact that the bird was swimming in the open - an uncommon position for any gallinule, but especially rare for PUGA. There is a paucity of information and relatively few photos of either species in this situation.

My general impression based upon the structure and seeing both species quite frequently (I just saw a juvenile PUGA a couple of hours ago), especially from the first photo, is of a COGA. Although I don't think the evidence here is clear enough to support either species, I'd have an easier time believing COGA than PUGA.
David W. 7 Jan 2022 No, ID I am torn about this record, leaning toward NO. That white "racing stripe" is prominent in most of the photos, and often occurs far above the water line (like a Moorhen/Common gallinule). The red on the bill seems to extend all the way to the top of the bill shield, but that may be an artifact of blowing up the photo past its useful size (i.e. edge effects). The habitat is entirely wrong, as this species is very closely associated with thickly vegetated marshes rather than open water adjacent to a sandy beach. It is reported to swim infrequently and reluctantly. When swimming, the Purple gallinule is reported to have a steeply upsloped straight back, which this does not.  I am willing to be convinced, but am currently skeptical.

Intriguing record.

2nd round:  

1 Feb 2022 No, ID No further thoughts.
Kevin W. 30 Dec 2021 No, ID In spite of the observer's insistence on this being a Purple Gallinule, the photos seem to contradict the description, particularly the white mark across the wing. It looks like a Common Gallinule to me. I'm interested to know others' thoughts.

2nd round:  

3 Feb 2022 No, ID I remain unconvinced that this is a Purple Gallinule.
