First Nest Records of the White-throated Hawk (buteo Albigula) in Argentina
Bibliographic record
Abstract
As part of an ongoing study of Swainson's Hawks (Buteo swainsoni) in southwest Idaho since 1995, we regularly check 50-80 nesting territories each year to determine occupancy and breeding success, to identify banded adults, and to detect turnover.Broods with four young Swainson's Hawks are not unusual in southwest Idaho.We have found four young at 13 of 174 nests (7.5%) in which broods were counted between 1996-2000.Here, we report the only nest we have ever found that contained five young.We observed the nest on 5 and 7 July 1999 and counted five young on both days.The nest was in a box elder (Acer neg'undo) tree 9 m above the ground, south of the city of Kuna.We counted the 31-39-day-old young through a 20 X 60 spotting scope and photographed the nest from a distance of about 50 m.Nests with five eggs and young are unusual in Swainson's Hawks (England et al. 1997 in A. Poole and F. Gill [EDS ], The Birds of North America, No. 265, The Philadelphia Academy of Natural Sciences, Philadelphia, PA and The American Ornithologists' Union, Washington, DC U.S.A).A report of 5-and 7-egg clutches in Manitoba (Criddle 1915, Ottawa Nat.Nov. 94-97) is questionable.Two contained five eggs and the third had seven eggs.The nest that contained seven eggs was on the ground and was a bulky bunch of large sticks with a bark lining.It is questionable because it better fits the description of a Ferruginous Hawk (Buteo regalis) nest which typically has 4-7 eggs (Murphy et al. 1969, Brigham Young Univ.Sci.Bull., Biol.Set., 10: 25-36).The only record of a nest with five young was made by Houston (1998, Bluejay, 56:154) who reported a nest with five young in Saskatchewan.M.

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.
