Abstract
Of the three subspecies of Barred Owl (Strix uaria) in North America, two occur in Tennessee (A.O.U.1957).The Florida subspecies (S.V. georgim) ranges across the deep south from east Texas to coastal North Carolina, as well as central Arkansas and west Tennessee.OnIy Shelby, Fayette, Hardeman, Tipton, and Haywood counties in southwest Tennessee seem to be included in the range of this subspecies (Karalus and Eckert 19731, although this list may be incomplete.The northern subspecies (S.V. varin) is much more widespread, occurring from Oklahoma, northern Arkansas, Tennessee, northern Georgia, and Virginia northward through the northern and eastern U.S. and across southern Canada.It seems to occur in Lake, Obion, and Weakley counties of northwest Tennessee (op.cif.), as well as most of middle and east Tennessee.A s coordinator of the Raptor Rehabilitation Program at the Memphis Zoo and Aquarium, I see a n average of about 30 inpred or orphaned Barred Owls each year; but since 7993, only three S.V. varia have been brought in to the RRI?One was from Reelfoot Lake State Park in Lake County, but the other two were found further south in Xpton and Shelby counties.The Shelby County bird was found in late November.I have read about the differences in appearance of these two subspecies, but had little chance to study them until I recently viewed a large collection of skins at the Field Museum of Natural History in Chicago.There were well over 50 skins of each subspecies available.It would seem that gwrgica is a little darker than varia.However, the best way to separate the two is by the feathering of the toes.On wrin the feathering goes almost to the base of the talons, while the toes of georgica are almost totally naked (Figure 1).This difference would be difficult to see in the field except at close range in good light.The collection of varia at the Field Museum contained four birds taken in the Mid-South area, including an individual from Lake County, Tennessee.The others were from Arkansas (two) and Georgia during the winter.It may be that, while Barred Owls are usually quite sedentary, there is some migration during the winter, particularly among northern b~rds.Clearly the subspecific distribution of this owl in Tennessee needs further study.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
