For two months, a team of bird banders Naturalists Association of Southeast has been studied in spring migration banding station Grosa Island.
During the study, which began March 16 and ended on 15 May have been tricked birds every day.
A captured birds were fitted with a metal ring with the Ministry of Environment sent prior to their release.
The results have been included in the "project Piccole Isole" ringing in small Mediterranean islands, involving several stations in various coastal countries, and aims to study the migration of European passerines.
Grosa Island has been declared a Special Protection Area for Birds (SPA) and is an exceptional place to study migration.
Due to its geographical location, close to Cabo de Palos, many birds use the island as a resting place during their migrations to be the first site available to sighted land after crossing the sea MEDITERRANEAN.
In this study we have captured a total of 2289 birds of 45 species.
Of these, 1827 birds were ringed for the first time, while the rest had been banded previously.
The most abundant species was the musical Mosquito, with a total of 934 banding, noting that he carried a copy forwarded ring with Sweden.
This species, one of the most common birds in Europe, just below 10 grams.
Despite its small size, are migrating from their winter quarters in central Africa to central Europe and Scandinavia, which has to cross the Sahara Desert and the Mediterranean Sea.
ANSE made an initial part of migration studies Grosa Island in 2007, and plans to repeat this during the coming years in order to obtain a series of long-term data.
These sets of data for several years, analyzed along with all the seasons of "Piccole Isole project," provide insights into the migration of birds and the evolution of their populations.
The study was made possible thanks to the ringers completely voluntary and colleagues, mainly from ASEAN, and has received the approval and cooperation of the Directorate General of Natural Heritage and Biodiversity in the Region of Murcia, which has provided facilities and as transportation to the island.
