Birds of the Bloemfontein pentad 2905_2610: a review over a 30 year period
Bibliographic record
Abstract
The Bloemfontein pentad (2905_2610) is one of the nine pentads of the 2926AA quarter degree square used during the SABAP1 survey (1987 -1992) (see Harrison et. al 1992). Before SABAP1, Roos et. al (1985a, b, c) published a series of annotated checklists of the Bloemfontein district based on surveys by the ?Orange Free State Ornithological Society? (now BirdLife Free State) in Mirafra, which also includes the central parts of the city. After SABAP1, Kopij (2001) did several bird counts in the Bloemfontein area (references in Kopij 2001) including an annotated checklist of Navil Hill (Franklins Nature Reserve), and other bird surveys, which were all annotated in a \"Atlas of birds of Bloemfontein\"; he summarized data over a period between July 1993 to June 1998 (dates correct). Anecdotal bird observations of Bloemfontein birds were mostly published in Mirafra under \"sightings of interest\" or as short snippets. These include the first report dates of birds such as Common Starling, Indian Myna, Black-collared Barbet and other bird species. The birds of the 2900_2610 pentad (which includes the Free State National Botanical Gardens and Seven Dams area) were published earlier (de Swardt 2014).

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.
