Bibliographic record
Abstract
Reproductive biology of the Red-billed Scythebill (Campylorhamphus trochilirostris) and Black-billed Scythebill (C. falcularius) in Argentina. – The genus Campylorhamphus (Furnariidae: Dendrocolaptinae) is poorly known in terms of natural history and reproduction. Here we describe aspects of reproduction from three nests of the Red-billed Scythebill (Campylorhamphus trochilirostris) in the Chaco of Argentina, and from one nest of the Black-billed Scythebill (C. falcularius) in the Atlantic Forest of Argentina. One of the nests of C. trochilirostris was in a cavity excavated by a woodpecker. The remaining nests were in cavities formed by natural decay. Both species had a clutch size of two. Two adults participated in incubation at each nest, bringing pieces of bark when they entered the cavity. Incubation bouts were 50 ± 3 min (mean ± SE) for C. trochilirostris (n = 3) and 57 ± 13 min for C. falcularius (n = 8). The nest of C. falcularius was depredated during the incubation period. In C. trochilirostris both adults delivered arthropods to nestlings and removed fecal sacs. They brought food on average 5.8 times/h and removed fecal sacs 2.5 times/h when the nestlings were feathered. Campylorhamphus should be included among the genera of Dendrocolaptinae with biparental care, along with Dendrocolaptes, Xiphocolaptes, Dendroplex, and Lepidocolaptes, but in contrast to Dendrocincla, Xiphorhynchus, and Sittasomus.
Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
