Conservation of endemic parakeets of New Caledonia

En la isla principal de Nueva Caledonia se encuentran dos especies de loros vulnerables y endémicas. Se trata del Periquito cornudo y el Periquito de Nueva Caledonia. Sus principales amenazas, objeto de estudio, se presuponían el deterioro de su hábitat, y la introducción de especies exóticas, de cómo las ratas negras (Rattus rattus) y los gatos asilvestrados (Felis catus) y, en menor medida, la caza furtiva.

Horned Parakeet (Eunymphicus cornutus)
New Caledonia Parakeet (Cyanoramphus saisetti)
Conservation status: Category VU (Vulnerable) in the Red List of the IUCN
Wild population: 8.000 – 9.000, declining.
Captive population: Number unknown

Objectives
Este proyecto de investigación es el primero que se realiza en Nueva Caledonia y tiene por objeto definir con precisión las amenazas para estas especies y la incidencia de cada una de ellas. Se pretende, en consecuencia, desarrollar las medidas necesarias para su protección en el medio silvestre, con el fin de mejorar la catalogación de su status en la lista de la UICN, donde ambas aparecen como vulnerables.

Strategies
Studying the ecology of the birds, their geographical distribution density, altitude range (400 to 600 meters), the variety of plants that provide food, and the extent of the threat posed by mammals, especially those introduced.

Actions
The observation of these birds in the breeding season has been intense work, and by which means the project researchers have come to spend more than 11,000 hours per year in each case. Some of the answers have been found in the 91 species recorded as part of the diet of New Caledonia Parakeets, and 101 referenced to Horned Parakeets. The main threats come from the black rat and the wildcat. The researchers were able to identify these predators with the help of video cameras equipped with infrared lights. This way they could get the rate of predation on eggs and chicks, and document the reproductive behaviour.
