STATUS OF THE THREE‐WATTLED BELLBIRD (PROCNIAS TRICARUNCULATUS) IN THE NICOYA MOUNTAINS, COSTA RICA
Bibliographic record
Abstract
Abstract ∙ Wildlife conservation often relies on accurate data of species distributions, yet scientific knowledge is often limited in scope. Local knowledge and habitat mapping can provide additional information particularly useful in assessing the absence or presence of a species or population. In May 2015, we combined point counts, local interviews, citizen science databases, and habitat mapping to assess the presence of breeding Three‐wattled Bellbirds (Procnias tricarunculatus), a species listed as Vulnerable by the IUCN, in the Nicoya Mountains of Costa Rica, where a disjunct population had previously been reported. Our point counts, local interviews, and citizen science databases provided strong evidence that bellbirds no longer breed in the Nicoya Mountains, and our habitat mapping demonstrated that a minimum of 23% of the bellbird habitat is now pasture. We conclude that a putative historic resident population of this species is now most likely non‐existent in the Nicoya Mountains.Resumen ∙ Estatus del Pájaro Campana (Procnias tricarunculatus) en las montañas de Nicoya, Costa Rica La conservación de la vida silvestre se basa comúnmente en el conocimiento exacto de la distribución de las especies, sin embargo, este conocimiento es limitado para muchas especies. El conocimiento local y mapeo del hábitat pueden proveer información adicional, particularmente útil en la evaluación de la presencia o ausencia de especies o poblaciones. En mayo de 2015, combinamos puntos de conteo, entrevistas locales, bases de datos de ciencia ciudadana, y mapeo de hábitat para determinar la presencia de poblaciones reproductivas de Pájaro Campana (Procnias tricarunculatus), especie enlistada como vulnerable por la IUCN, en las montañas de Nicoya, Costa Rica, donde una población ha sido reportada previamente. Nuestros puntos de conteo, entrevistas a locales, y bases de datos de ciencia ciudadana indican que el Pájaro Campana no se reproduce en las montañas de Nicoya; nuestro mapeo de hábitat demuestra que un 23% del hábitat del Pájaro Campana ha sido transformado en pastizales. Concluimos que una supuesta población residente histórica de esta especie es ahora muy probablemente inexistente en las montañas de Nicoya.

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.
