First description of the nest and eggs of the Sooty-faced Finch
Bibliographic record
Abstract
Sooty-faced Finches (Lysurus crassirostris) occur in dense undergrowth of wet forests that border streams along the Caribbean slope of Costa Rica between 600 to 1500 m in altitude. Its distribution is from Cordillera de Tilaran in Costa Rica to eastern Panama (Slud, The birds of Costa Rica. Distribution and ecology. Bull. Amer. Mus. of Nat. Hist. 128, 1964; Stiles and Skutch, A guide to the birds of Costa Rica. Cornell Univ. Press, Ithaca, New York, 1989). On 5 May, 1993, 1 found a Sooty-faced Finch nest containing two eggs at the Reserva de San Ramdn on the Caribbean slope of Costa Rica (800 m; lO”13N ’ and 84”37W). ’ The nest was attached to a fern stem 1.5 m above the ground in primary forest. The nest was roofed and had a side entrance, the 15 X 13 cm cavity was lined with fern rootlets and bamboo leaves. A soft bulk of moss decorated with fern leaves and Selaginella surrounded the outer part of the cavity and extended, just touching the fern trunk, for 67 cm below the nest. The nest contained two short-oval shaped eggs (terminology of Harrison, Afield guide to nests, eggs and nestlings of North American birds. Collins, Toronto, Ontario, 1984) with the following dimensions and mass, respectively: 24.85 X 18.90 mm and 25.00 X 18.75 mm; and 4.5 and 4.6 g. The eggs were ivory-colored with vinaceous-pink spots (Smithe, Naturalists ’ color guide. Amer. Mus. Nat. Hist. New York, New York, 1975) covering most of the wide tip and dispersed speckles (of the same color) toward the narrow end. Embryonic development had just begun in one egg but not in the second. This is the first description of the nest and eggs of this species. The nest and eggs were deposited in the ornithology collection of the Museo National de Costa Rica.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model 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 teacher head, not a consensus.
