Return of a Red-eyed Vireo: A Transient or Breeder?
Bibliographic record
Abstract
ed-eyed Vireos {Vireo olivaceus] stop over, during both spring and fall migrations, on the forested dune ridge that separates Lake Manitoba from the Delta Marsh, Manitoba.A 3-km segment of this dune-ridge forest {study area described by Sealy 1980a, MacKenzie 1982) has been the focus since 1974 of an ongoing investigation into the ecology of a community of densely nesting species of insectivorous birds.An important part of this work has involved almost daily mist netting and banding, during the breeding seasons, of the resident breeding birds and in some years individuals that stop over in this forest during their migrations (see Sealy 1980b; den Haan 1982; Sealy and Biermann 1983).We believe that a Red-eyed Vireo banded in the dune-ridge forest in 1976 and recaptured in 1978 near its original banding site represents the return of a breeding bird, rather than a transient, despite the fact that Red-eyed Vireos have been recorded nesting only once on the study area.An AHY Red-eyed Vireo {flattened wing, 75 mm; weight, 17.7g), probably a female {see Godfrey 1966, Williamson 1971), was mist netted and banded {1370-35318) on 20 June 1976.This individual did not repeat in 1976, but was recaptured on 19 July 1978, 130 m west of its initial capture site.It was molting wing and body feathers when recaptured.This capture date suggests that this individual probably was not a migrant, although its status as a breeder on or off the study area was never established.Red-eyed Vireos migrate through the dune-ridge forest in spring, generally over a 2-week period in late May and early June {Table 1), a time that corresponds to their arrival in Manitoba generally {Lawrence 1958).Only a few individuals have been seen or captured in mid-summer, but a detectable movement of birds occurs again in late August and early September {Table 1).In spring, singing individuals are particularly conspicuous.

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.
