One (1989-14) on 23 Dec 1989, Evangeline: ½ mi. E of Hwy. 13 on gravel road, approximately 2 mi. N of Hwy. 10. This record involved a brief sighting of a species for which there are very few well-documented Louisiana records. Although the description superficially indicated American Tree Sparrow, dissenting members were not convinced that the bird was even a Spizella versus a Melospiza. Because Swamp Sparrows can show these same field marks (e.g., bi-colored bill, rufous cap with grey center, and dark breast spot) used to identify this bird, members were reluctant to accept the record without more extensive details.
One (86-1) near Ball, Rapides Parish, on 18 December 1985.
One (1997-64) on 20 December 1997, La Salle: Nebo. The main mark given to identify this individual as an American Tree Sparrow was a dark spot on its breast. Members considered this insufficient to eliminate superficially similar sparrow species (e.g., Swamp Sparrow) or a sparrow missing feathers that could appear as a spot.
One each day (2012-149) on 23 November and 26 December 2012, Ouachita: Ruston, Louisiana Tech University campus, over Carson-Taylor Hall. Identification was based on single flight calls captured by an automated recording device. The sound clips were so brief/faint that they were difficult to distinguish. Although printed sonograms were provided and were suggestive, there was little analysis/discussion of the data and one sonogram also seemed close to or within the range of variation of other species (e.g., Savannah Sparrow).
