Current status of Cuban threatened birds: Case studies of conservation programs
Bibliographic record
Abstract
Abstract: Cuba is the largest island in the Caribbean, with many ecosystems supporting high biodiversity. The island has three main mountain groups as well as the major natural wetlands of the Caribbean. It is home to over 350 bird species. Twenty-three Cuban species are considered threatened, and nine of these are under study by several institutions, including the Universidad de La Habana, the Instituto de Ecologia y Sistematica (Institute of Ecology and Systematics), and the Empresa para la Conservacion de la Flora y la Fauna (Agency for the Conservation of Flora and Fauna). Here, we describe some of the results of our studies of Cuba?s threatened birds, as well as discuss current conservation efforts. Study cases where research and management have been successful in improving the current status of the birds are presented. Efforts to manage Cuban Parrots (Amazona leucocephala) and Greater Flamingos (Phoenicopterus ruber) have been the most successful of the conservation efforts. Keywords: Amazona leucocephala, Charadrius melodus, conservation, Cuba, Cuban Parrot, Dendrocygna arborea, Greater Flamingo, Grus canadensis nesiotes, Phoenicopterus ruber, Piping Plover, research institutions, Sandhill Crane, threatened birds, West Indian Whistling-Duck Resumen:Estado actual del conocimiento de las aves amenazadas de Cuba: Estudios de caso de programas de conservacion- Cuba es la mayor isla del Caribe, con un gran numero de ecosistemas diferentes que soportan una elevada biodiversidad. La isla posee tres cadenas montanosas y los humedales mas importantes del Caribe. Alberga una ornitofauna de mas de 350 especies de aves. Veintitres especies de aves se consideran amenazadas y, de ellas, nueve estan bajo estudio en diferentes instituciones que incluyen La Universidad de La Habana, el Instituto de Ecologia y Sistematica y la Empresa para la Conservacion de la Flora y la Fauna. En el trabajo se describen algunos de los esfuerzos y resultados de nuestros estudios sobre las aves amenazadas. Se presentan ademas algunos estudios de caso donde la investigacion y el manejo han tenido exitosos resultados y han mejorado el status de las especies involucradas. Entre los casos de manejo mas exitosos se plantean el de la Cotorra (Amazona leucocephala) y el del Flamenco (Phoenicopterus ruber).

L'ile poss ede trois groupes de montagnes importants ainsi que les plus grandes zones humides de la Caraibe. C'est l'habitat de plus 350 especes. 23 especes cubaines sont considerees comme menacees et neuf d'entre elles font l'objet d'etudes par plusieurs institutions, dont l'universite de La Havane, l'institut d'Ecologie et de Systematique ainsi que l'Agence pour la Conservation de la Flore et de la Faune. Nous decrivons ici certains des resultats de nos etudes sur les oiseaux menaces de Cuba et nous discutons des efforts de conservation en cours. Des etudes de cas sont presentees ou la recherche et la gestion ont ete efficaces en ameliorant le statut actuel des oiseaux. Les efforts de gestion les plus couronnes de succes concernent l'Amazone de Cuba (Amazona leucocephala) et le Flamant rose (Phoenicopterus ruber).

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.
