Distribution, Nesting, and Vocalizations of the Black-banded Owl (ciccaba Huhula Albomarginata) in Argentina
Bibliographic record
Abstract
Resumen.-Distribución, nidificación, y vocalizaciones de la Lechuza Negra (Ciccaba huhula albomarginata) en Argentina.-La Lechuza Negra tiene una amplia distribución en el Neotrópico y su historia natural es poco conocida.Reportamos nuevos registros que extienden la distribución y describen nuevos ambientes para la especie en la Selva Atlántica de la provincia de Misiones, Argentina.Encontramos que la Lechuza Negra es la más rara de las grandes lechuzas de bosque en esta provincia.Seguimos dos nidadas ubicadas en la horqueta principal de un ejemplar vivo de anchico (Parapiptadenia rigida: Fabaceae).La cámara del nido estaba a 15,2 m de altura, protegido por epífitas y tres ramas verticales grandes.En octubre-noviembre 2010 el nido contenía un pichón, y en septiembre-noviembre 2012 un huevo blanco.Ambos miembros de la pareja llevaron alimento al pichón y defendieron el nido contra los investigadores, pero un solo individuo parecía incubar el huevo y empollar el pichón durante el día.El pichón fue alimentado con mariposas nocturnas grandes (Sphingidae: Lepidoptera), incluso Manduca spp.y Neococytius spp.Describimos un variado repertorio vocal y sonidos mecánicos (hechos con las alas) que parecerían ligados a la actividad reproductiva.Los aspectos de la nidificación descriptos fueron similares a los de la Lechuza Blanco y Negro (Ciccaba nigrolineata), su pariente más cercano, y a veces considerada como una misma especie.Abstract.-The Black-banded Owl has a large distribution in the Neotropics but little is known about its life history.We report new records that extend the known distribution and add new habitats within the Atlantic forest province of Misiones, Argentina.We found the Black-banded Owl to be the least abundant of the large forest owls in the province.We followed two nesting attempts in the main fork of a living angico (Parapiptadenia rigida: Fabaceae).The nest chamber was at 15.2 m above ground, and protected by epiphytes and three large vertical branches.In October-November 2010, the nest contained one nestling, and in September-November 2012, it contained one white egg.Both adults brought food to the nestling and defended the nest against researchers, but only one individual seemed to incubate the egg and brood the nestling during the day.The nestling was fed large nocturnal moths (Sphingidae: Lepidoptera), including Manduca spp.and Neococytius spp.We describe a diverse vocal repertoire and a mechanical sound (made with the wings) that seem to be linked to reproduction.Aspects of nesting are similar to those of the Black-and-white Owl (Ciccaba nigrolineata), the species' closest relative and sometimes considered the same species.

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.
