One (1982-27) on 29 Dec 1982, Plaquemines: Triumph, Fort Jackson; NAB37(3):310 (record packet also included R. J. Newman’s CBC summary that provides additional supporting, albeit second-hand, details). This report was written and submitted several years after the observation by only one of the observers present that day. The swift did not vocalize and its identification was based primarily on one character (rump color). This record received a split vote with only three members voting to accept the record on the second circulation.
Four (1992-26) on 14 Feb 1992, East Baton Rouge: Baton Rouge, First United Methodist Church, 430 North Boulevard; AB46(2):277 indicates “four unidentified swifts seen throughout the winter at a roost site in E. Baton Rouge.” Four swifts were observed at dusk disappearing into the church chimney. The observer heard the birds, but did not elaborate about their calls except noting that they gave a "faint chip.” Although presumably Vaux’s based on that species’ pattern of late winter occurrence, the physical description of the birds and of their call notes were considered inadequate for a diagnostic identification. Although there is no currently accepted winter record of Chimney Swift or other Chaetura swift species, the LBRC continues not to accept winter Chaetura as Vaux's by default in the absence of adequate documentation.
One (1992-58) on 22 Nov 1992, Iberville: a few mi. N of St. Gabriel. This difficult record received split votes through the first three circulations and went to a Discussion vote at a meeting. Although an experienced observer submitted this record, the bird was not photographed, did not call, nor (not surprisingly for the date) could it be compared to other swift species. Therefore, identification criteria were relatively subjective. Members discussed the pattern of records of Vaux’s and Chimney swifts, and noted that this record was only marginally outside the late dates for fall occurrence of Chimney Swift. Members discussed the subjective nature of size and wing length, and took into consideration that late fall Chimney Swifts could be completing primary molt and might appear shorter-winged. Some members were also concerned that the description focused more on elimination of Chimney Swift than on what the bird actually looked like. Ultimately, the record was not accepted on a 2-5 vote.
Three (1997-10) on 5 January 1997, East Baton Rouge: Baton Rouge, First Methodist Church at intersection of I-10 and North Blvd. Although most Members believed that this species was most probable due to location and time of the year, no diagnostic characters were provided to support the identification.
One (2007-004) on 19 January 2007, East Baton Rouge: Baton Rouge, University Lake on E. Lakeshore Dr. Views were distant, and vocalizations were not heard. Although this species is generally considered the “default” winter swift species in Louisiana, a majority of Members considered the documentation too weak for the record to stand on its own and were not willing to automatically accept as Vaux’s based on probability.
One (2008-065) on 15 March 2008, East Baton Rouge: Baton Rouge, Arsenal Park at Capitol Lake. Most Members believed that the description of this single silent swift was not adequate to eliminate an early Chimney Swift.
