Abstract:

The Andean Condor (Vultur gryphus) is listed in CITES Appendix I. In the last decades, the population has suffered an apparent decrease along its entire cordilleran distribution. Given that this species possess a great flight capacity, it is crucial to know how far these birds usually travel in order to design and undertake specific actions for their conservation. The objective of the present study was to determine the sizes of the home range and the occurrence of seasonal variations in a male specimen of Andean Condor released in Santa Cruz, Patagonia Argentina. A total of 5206 points of satellite tracking information were analyzed. Using the minimum polygonal convex method (MPC) the total and seasonal home range areas were calculated. Circular statistics was used with the purpose of determining if the condor movements presented seasonal variation or if they were distributed at random within the year. To evaluate uniformity, Rayleigh's test was used. The estimated total home range for this condor during the full period studied was 24.311,7 km2. In addition, our results indicate that, for this bird, the home range areas vary according to the season. The distribution of the flights during the year is not at random, there are periods where distance traveled is longer. On the basis of the big territorial requirements of this species and the present results, it becomes necessary to define the specific requirements that may allow its conservation at a regional level. © The Neotropical Ornithological Society.
