Notes made by the Webmaster (and
acting Secretary), Milt
Recap of Checklist Update Process:
|
General Statement of Purpose:
(This is the official checklist of the birds of Utah as viewed by the
Utah Bird Record Committee)
The UBRC checklist is meant to
be a list of the birds that the Committee has documented in the state of
Utah with "Codes" that give a general idea of the time of year
that they are present in the state (status codes), and how likely you
are to find them when you're in the appropriate habitat and season
(abundance codes). In additions we indicate which species we would like
to receive sight records for, so we can continue documenting the species
of this list.
The procedure we followed
to update the checklist so that the codes reflect the present activity
of the birds in the state.
Since we passed the new code definitions for the checklist, we've been
trying to implement them in our checklist update. We've learned some
things in the process, that we can report, so that we can create an
appropriate checklist as of "Fall 2026:"
- The new wording for the Accidental and Occasional codes should be
changed from "in a ten year period" to "in the last ten years" (to be
more clear) and the Accidental code should be simplified (basically
leaving out
"less than 3 in the past 30
years" (which basically restates the frequency before and after
this phrase). (Other suggestions are welcomed).
- The
definition of the "Extirpated" didn't fit the proposed species suggested
to be in that group. Even after several attempts to redefine the term,
we couldn't find an appropriate definition that would provide a clear
and meaningful designation of this group. It looks like the definition
of Accidental ("Not expected and out of normal range") would fit this
group better). An example is Inca Dove. I asked Google about the
normal range (so you know it's all true! - JOKE), and it told me that
the range has actually been expanding, except for the northern edge,
because of cold sensitivity, and eBird indicates that there have been a
couple of sighting in SE Utah, (2017 (SJ. Co. and 2014 in Grand Co.), so
"O" might be suggested according to this.. I think "A(13)" might be a
better indication of what to expect , for Utah, presently, instead of
"E" (See the
"notes" below)
- The definition of "Irruptive" was also problematic. There was a
group 6 or 7 birds that were mentioned as possible members of this
group, but a definition that would fit, to make this a cohesive group
with a clear meaning, was hard to find. (It might be better to use the
"non-irruptive codes" for these species to avoid confusion). ((See
the "notes" below)
Moving forward:
After we cleared up the code definitions (see above), we have made a
composite checklist (Checklist
with suggestions and input),
which shows the proposed changes to the checklist and give
everyone on the committee a chance to add their suggestions and
comments. Where there are different suggestions we can use a voting
form to get the opinions of the committee as to which codes we should
use for our checklist.
Here's our suggestion for the new checklist with an
updated code system and also suggestions for individual codes. Vernon
and I have checked the eBird Bar Charts for the year range of 2016 to
2026 (data for an updated version - the suggestions by Bryant fit the
eBird date very well), and also applied the new codes that have a
"documented sightings" number as part of the definition and used
suggestions from other committee members who have participated in the
project . Your suggestions and comment are always welcomed and needed
for producing the UBRC checklist of Utah birds.
Latest
draft of checklist
Three
possible options to consider on how to proceed:
1 - Review the checklist and add suggestion and comments so we can make
appropriate changes.
2- Make a check list with only the names of the species and an
indication of which species we'd like to review. .(A lot of
records committees have gone for this option)
3- Just use the old checklist until we can get enough volunteers to
form a checklist subcommittee to comply with the bylaws.

Here's a page we consulted for Historical Utah Checklists
(1975 to present):
About the checklists
|
|
Considering the Irruptive Code: |
| |
History: Irregular (similar
to Irruptive) was used in the
2004 & 2009
checklists for these species:
- Gray-corwned Rosy finch
- White-winged Crossbill
- Evening Grosbeak
|
| |
Code Definitions tried:
- "Present some years in numbers corresponding to rare or
greater, but absent or scarce other years"
_ "Not found annually, but some years found with irregular,
large-scale movements beyond the normal winter range
- "A species which occurs in Utah only when it undergoes irregular,
large-scale movements beyond its normal winter range"
When applied to the suggestions for
"Irruptive species, the definitions didn't seem to make much sense - they didn't
seem to fit. We asked for an appropriate definition, that fits the species that
have been proposed, but only the three above have been offered. Bryant responded
that the species he suggested were definitely "irruptive," but didn't proposed
another definition, and resigned from the checklist subcommittee since an
additional volunteer was not found.
In examining the prospects of having "IP" or "IW" code, we decided that the
"present codes" would offer more useful information ("UP" and "RW" for example),
and chose to use those instead of having an "Irruptive" code for our proposed
checklist..

Links to a separate document that would explain the
situation for each species (which Bryant provided), was suggested,
but doesn't seem appropriate for our checklist
codes which are meant to be be a simple, general view of the status of
each Utah species. |
| |
|
|
Considering the Extirpated Code: |
| |
History: Extirpated
was used in the
1975 checklists
for this species::
- California Condor
|
| |
Code Definitions tried: for Extirpated:
- "No longer present in Utah"
- "Formerly nesting species that has not nested in Utah for at least 30
years and is no longer present"
- "No longer present in Utah OR not nesting any longer for more than 3
years (or some other number that would be appropriate)"
|
| |
Below are Bryant's suggestions for
Extirpated species:
|
| |
Extirpated species |
Note |
|
|
| |
American Black Duck |
- First seen in 1938 last seen in 1990
- Was introduced for hunting, but wasn't able to establish a viable
population. |
| |
Passenger Pigeon |
Last seen anywhere in the world in 1900 - definitely extirpated but
this species is not found on the Utah checklist. |
| |
Whooping Crane |
- First seen in 1996. Last seen in 2000
- Attempt to reintroduce this species along an old migration route was
unsuccessful. (Also not on the Utah checklist). |
| |
LeContet;s Thrasher |
- Normal range along border of California and Arizona, north into
Nevada.
- Five sighting in Utah from 1891 to 1990 mainly in Beaver Dam Slope and
Mountains. (The normal shifting of species range may be why it hasn't
been seen in Utah for a long time).
- |
| |
Inca Dove |
It looks like this species, which has previously
nested in Utah, but has no longer
been nesting for maybe 10 years, fits one of the two level of
extirpation mentioned by Bryant, but I haven't been able to find where this definition comes
from. But in any case, "extirpated" does doesn't seem to fit
this species as well as the definition of Accidental, which is "Not
expected and out of normal range."
- Google says that the range has actually been expanding,
except for the northern edge, because of cold sensitivity. (I don't
know the validity of this Google information). The eBird data
indicates that there have been a couple of sighting in SE Utah, (2017
(SJ. Co. and 2014 in Grand Co.). Neither sighting was sent into the
committee, but this might suggest that "A(13)" might be a better indication of
what to expect for Utah, presently, instead of "E"
- This
species was taken off the Review List in 2002, but put back on in
2025. The last eBird sighting was by Bryant in 2010 at Beaver Dam Wash.

General
results of the new Codes |
| |
The new definitions of
"Occasional" and "Accidental" have decreased the number of species
in the "Accidental" category (which included almost all of the Review
Species) and increased the number of "Occasional" and "Rare" species.
Since Review Species are the ones that the Records Committee are most
concern with, it is probably good to differentiate between the more
rare and more common Review Species. (The new category
definitions, linked to the number of documented sightings, looks like
they works very well!)
The use of the eBird data, mostly in using the bar charts for
the species of Utah, probably increased the abundance of quite a few
species. This could be due to interpretation of the bars on the
chart, or because of the increased input from all of the regular
birders that use eBird, or the actual increase in birds that are now
in Utah compared to the time of the last checklist update. (This is a
good issue to think about in our future checklist updates). |

- Suggestions from Committee Members:
Bryant:
- Bryant suggested the Code System changes (A,B, and C), which were
voted on by the committee.
Vote (26 July 2026) -
B was accepted
He sent in suggestion for changes which are in the "Bryant column"
of the
Compilation list.
Jeff:
- Jeff sent in som individual codes and suggested a definitions for
"Irrupted "
"A species which occurs in Utah only when it undergoes irregular,
large-scale movements beyond its normal winter range." I think
Bohemian Waxwing and Redpolls would fall into this Abundance code based on
this definition.
-
- Suggestions for individual species:
- - Vaux Swift as occasional migrant (OM) rather than rare migrant (RM)
now that we've removed it from the Review List
- White-rumped Sandpiper as rare migrant (RM) rather than accidental (A)
- Red-throated Loon as rare winter or rare migrant rather than accidental
(A) since we have seen them during early and late winter months
- Flammulated Owl as common summer (CS) rather than uncommon summer (US)
- Boreal Owl as uncommon (U) rather than occasional (O)
- Kevin:
- Kevin suggested individual codes for some of the species in Washington Co.
and others:
"Change Inca Dove from RP to O, as it hasn't been observed since 2023, and the
single reliable flock in Washington County has blinked out.
Upgrade Anna's Hummingbird from RW to UP (or maybe even CP in Wash Co.)
Sprague's Pipit: Change from UP to A
Least Sandpiper is listed as CT; should this be CM?
I found two birds listed as OP; this seems contradictory to me? Great
Black-backed Gull and Boreal Owl"
- David:
- Suggested some species that for the Irruptive category:
David's suggestions:
- Redpoll (now - RW - as above)
- Bohemian Waxwing - (now UW as above)
- White-winged Crossbill (now O, Bryant suggests RP)
(? Other species we may consider:)
- Lark Bunting (now R)
- Evening Grosbeak ( now - UP)
- Pine Grosbeak (now UP)
