2023 Checklist

                                       Briefly  

Periodically, the checklist committee of the American Ornithology Society will split, merge, or rename species and reorder the list according to their studies on  how the species are related.  This updated checklist for Utah reflects these changes.

Some or the more noticeable changes are:  our Northern Goshawk had been split from the Eurasian species and is now called the American Goshawk.  The Pacific-slope  and  Cordilleran Flycatchers were merged, after a previous split, and are again called Western Flycatcher.  There are also new genus and species names which will show up in the taxonomic lists. Here are some changes:

Northern Goshawk is now American Goshawk, 
   and  Accipitor atricapillus rather than A. gentilis. (from a split)
Northern Harrier has a new species name: C.hudsonius
    rather than Cirus cyaneus, which is the Hen Harrier of Eurasia.
Ruby-crowned Kinglet is now in a different genus than
   Goldern-crowned Kinglet - Corthylio rather than Regulus
The genus name for five warbler has been changed to Leiothlypis.
   They are: Tennessee, Orange-crowned, Lucy's, Nashville and Virginia's Warblers.

2021 Checklist

  
Briefly

With the change in the bylaws requiring physical evidence or two accepted sightings without physical evidence, to put a species on our main checklist, there were six species removed from our official checklist and put on the new Provisional Species List.

The new Provisional Species List contains species that are NOT on the main checklist but have one sight record that has been accepted by the Committee without physical evidence.  The six of the seven species on this list that were removed from the previous checklist are: Garganey, Bar-tailed Godwit, Elf Owl, Louisiana Waterthrush, Field Sparrow and Baird's Sparrow.  The other species on this list is Blue-throated Mountain-gem which was added to the list after accepting a record taken from an old report on a sighting of this species.

2019 Checklist

  
Briefly

The code system for the Bird Checklist for Utah has been simplified removing the "Fairly Common" and the "Irregular" categories from the "Abundance Codes" and "Provisional species" and the "Northern Utah" designations for the Status Codes. All codes were reviewed and updated when appropriate.. The names and order of the birds are according to the 7th edition of AOU checklist, 58th supplement.

Since the 2018 checklist,  four new species (Pacific-slope Flycatcher, Dusky-capped flycatcher, Blue-footed Booby and Great Black-backed Gull) have been added to the checklist and one has been removed because of a species merge. (Thayer's Gull is now a subspecies of Iceland Gull), making a total of 465 species on this checklist.

Briefly
The Utah Bird Checklist for Utah has been thoroughly revised and updated. 
The abundance and status codes are current and
the names and order of the birds is according to the latest AOU checklist.
In March of 2004, 22 new species were added, two were taken off and the names of five species
were changed. Making a total of 426 when published
In April of 2005, four new species were added making a total of 430 species on the checklist..

 | 2004 Utah Checklist | 
  

2004 Revision of the Checklist:

The Checklist committee was made up of four members of the Utah Bird Records Committee.  Terry Sadler and Merrill Webb were co-chairmen of the committee, Ron Ryel was a consultant for the northern part of the state and Rick Fridell was a consultant for the southern part of the state.  Two new abundance codes were added to round out the set.  A "fairly common" category was added to bridge the gap between "common" and "uncommon," and a new category "accidental" was added to indicate that the species would be out of its normal range, as opposed to an "occasional' species which would not be seen every year, but would be expected to show up now and then.  A "^" code was added to indicate that the species was found primarily in the northern part of the state as a complement to the already existing "*" code which indicates that the species is found primarily in Washington County in the southwest corner of Utah.

All members of the committee submitted their abundance and status codes for all of the species independently and then the differences were discussed and the  final decisions were made.  It is significant to note that there were very few differences among the codes of all four committee members and the differences that did come up were quite minor.   This would possibly indicate that although the codes are not scientific, they do describe very well how often you would expect to see a certain species during the course of normal observation.

Names and list order:

The name and list order correspond with the recently updated 7th American Ornithologist's Union Check-list of North American Birds and the 44th supplement of that Check-list.  There were some name changes and new species split from old ones:

• American Three-toed Woodpecker, Picoides dorsalis, was separated from the Three-toed Woodpecker of Europe, Picoides tridactylus.

• Greater Sage-Grouse was renamed when the old "Sage Grouse," species was split.

• Gunnison Sage-Grouse became a new species, Centrocercus minimus, as a split-off of  the above mentioned "Sage Grouse."

• Long-tailed Duck was rename, for reasons of political correctness most likely, from "Oldsquaw."

• Rock Pigeon is the new name for the old "Rock Dove," better placing it with a more similar group of birds.

• Wilson’s Snipe, Gallinago delicata, was split from the Common Snipe, Gallinago gallinago, of Europe and Asia.

• Black-billed Magpie became a new species Pica hudsonia being split from the Magpie of Europe and elsewhere, Pica pica.

The main changes in order are that the "duck, swans and geese" group (Answeriiformes) has been moved to the beginning of the list and is followed by the the "grouse and quail" group (Galliformes).  Other than that, the order is about the same.

Species added to the 2004 checklist:

There were 22 new species added to the 1998 checklist in March of 2004. All but one of them were new sightings for Utah.  The Gunnison Sage-Grouse was added because of a species split: (Click the name to see the record submitted to the Records Committee). 

• Blue-winged Warbler

• Canyon Towhee

• Cassin's Sparrow (2nd record)

• Curve-billed Thrasher

Species removed from the previous checklist:

• Bar-tailed Godwit

• Laughing Gull
