2017 Annual Report
TEXAS BIRD RECORDS COMMITTEE REPORT FOR 2017
4710 Canyonwood Drive, Austin, Texas 78735
The Texas Bird Records Committee (hereafter "TBRC" or "committee") of the Texas Ornithological Society requests and reviews documentation on any record of a TBRC Review List species (see TBRC web page at http://www.texasbirdrecordscommittee.org). Annual reports of the committee’s activities have appeared in the Bulletin of the Texas Ornithological Society since 1984. For more information about the Texas Ornithological Society or the TBRC, please visit www.texasbirds.org. The committee reached a final decision on 100 records during 2017: 89 records of 39 species were accepted and 11 records of 10 species were not accepted, an acceptance rate of 89.0% for this report. The committee also added 2 species to the Supplemental List. In addition, 1 record wasn’t circulated due to taxonomy change (lumped with a non-review species) and 1 additional record was withdrawn by the observers. A total of 159 observers submitted documentation (to the TBRC or to other entities) that was reviewed by the committee during 2017.
The TBRC accepted 3 first state records in 2017: White-tailed Tropicbird, Amethyst-throated Hummingbird, and Variegated Flycatcher. Thayer’s Gull and Iceland Gull were lumped into Iceland Gull so Thayer’s Gull was removed from the Texas State List. These 3 additions and the 1 removal bring the official Texas State List to 647 species in good standing. This total does not include the 5 species on the Presumptive Species List, nor the 2 species on the Supplemental List.
In addition to the review of previously undocumented species, any committee member may request that a record of any species be reviewed. The committee requests written descriptions as well as photographs, video, and audio recordings if available. Information concerning a Review List species may be submitted to the committee secretary, Eric Carpenter, 4710 Canyonwood Drive, Austin, Texas 78735 (email: firstname.lastname@example.org). Guidelines for preparing rare bird documentation can be found in Dittmann and Lasley (1992) or at http://www.greglasley.net/document.html.
The records in this report are arranged taxonomically following the AOS Check-list of North American Birds (AOU 1998) through the 58th supplement (Chesser et al. 2017). A number in parentheses after the species name represents the total number of accepted records in Texas for that species at the end of 2017. Species added to the Review List because of population declines or dwindling occurrence in recent years do not have the total number of accepted records denoted as there are many documented records that were not subjected to review (e.g. Brown Jay, Pinyon Jay, Tamaulipas Crow, and Evening Grosbeak). All observers who submitted written documentation or photographs/recordings of accepted records are acknowledged by initials. If known, the initials of those who discovered a particular bird are in boldface but only if the discoverer(s) submitted supporting documentation. The TBRC file number of each accepted record will follow the observers' initials. If photographs or video recordings are on file with the TBRC, the Texas Photo Record File (TPRF) (Texas A&M University) number is also given. If an audio recording of the bird is on file with the TBRC, the Texas Bird Sounds Library (TBSL) (Sam Houston State University) number is also given. Specimen records are denoted with an asterisk () followed by the institution where the specimen is housed and the catalog number. The information in each account is usually based on the information provided in the original submitted documentation; however, in some cases this information has been supplemented with a full range of dates the bird was present if that information was made available to the TBRC. All locations in italics are counties. Please note that the county designations of offshore records are used only as a reference to the nearest point of land.

ADDED TO SUPPLEMENTAL LIST
The TBRC maintains a Supplemental List of those species that are not on the State List but for which there is at least one record determined to be “unaccepted, natural occurrence questionable” and with respect to that record, for which a majority of members believe there is enough potential for natural occurrence for inclusion on the Supplemental List. If a record of a species not on the State List is not accepted on the grounds of questionable natural occurrence, but all members agree that the bird’s identity was established, then any member may move to add the species to the Supplemental List. The species will then be added to the Supplemental List with a majority vote, either at a meeting or through other voting means. The following species were added to the Supplemental List during 2017.
Tropical Mockingbird (Mimus gilvus). One at Sabine Woods, Jefferson from 18 April - 28 July 2012 (DJ, TFe, SM, JW, JoP, MS, MLi, TFi, EC, RP, IS, BP, MR, BN, BSt, AW, HS, SW; 2012-36).
Striped Sparrow (Oriturus superciliosus). One east of Granger Lake, Williamson from 11 January - 7 April 2015 (RK, TF, CW, CT, HF, RP, AW, BN, BSt, FB, CL; 2015-04).
A number of factors may contribute to a record being denied acceptance. It is quite uncommon for a record to not be accepted due to a bird being obviously misidentified. More commonly, a record is not accepted because the material submitted was incomplete, insufficient, superficial, or just too vague to properly document the reported occurrence while eliminating all other similar species. Also, written documentation or descriptions prepared entirely from memory weeks, months, or years after a sighting are seldom voted on favorably. It is important that the simple act of not accepting a particular record should by no means indicate that the TBRC or any of its members feel the record did not occur as reported. The non-acceptance of any record simply reflects the opinion of the TBRC that the documentation, as submitted, did not meet the rigorous standards appropriate for adding data to the formal historical record. The TBRC makes every effort to be as fair and objective as possible regarding each record. If the committee is unsure about any particular record, it prefers to err on the conservative side and not accept a good record rather than validate a bad one. All records, whether accepted or not, remain on file and can be re-submitted to the committee if additional substantive material is presented.
Barrow's Goldeneye (Bucephala islandica). One at Hornsby Bend, Travis on 17 November 1979 (2017-09).
Red-billed Tropicbird (Phaethon aethereus). One at Rockport Harbor, Aransas on 23 April 2016 (2016-31).

Buff-breasted Flycatcher (Empidonax fulvifrons). Two at Tobe Canyon, Davis Mountains Preserve, Jeff Davis on 16 July 2017 (2017-32).
Rose-throated Becard (Pachyramphus aglaiae). One at Paradise Pond, Port Aransas, Nueces on 1 April 2008 (2016-24).
Pacific Wren (Troglodytes pacificus). One at Palo Duro Canyon, Randall on 26 November 2014 (2015-81). One at McKittrick Canyon, Guadalupe Mountains N.P., Culberson on 23 November 2016 (2016-89).

Iceland Gull (Larus glaucoides). One at Bolivar Flats, Galveston on 11 April 2017 (2017-12). This record was not circulated as Iceland Gull was lumped with Thayer’s Gull by the AOS in 2017. Thayer’s Gull is now considered a subspecies of Iceland Gull and the non-Thayer’s Iceland Gull records in Texas to this point have all been considered “Kumlien’s” Iceland Gull. “Kumlien’s” is widely regarded to be an intergrade between Thayer’s and the nominate subspecies.
