Nest boxes at the Camí des Correu

The Camí des Correu as its name suggests in Mallorcan (post path) is an old route used to join the towns of Esporlas and Banyalbufar and for the last five years has been used for nest box study and monitoring of their occupation by insectivorous birds.

In these types of studies the yearly accumulation of information is important to be able to determine nest box occupation, species interrelation, phenology etc.
Nest boxes can be a constant source to study the biological different aspects of the birds that occupy them, at the same time favouring nesting by species that prey on insects that damage the forests and are an excellent tool for environmental education.

This year, still awaiting a final count, around 20 boxes have been occupied by Great Tit (P. major) and a dozen by Blue Tit (P. caeruleus).
Once the nest boxes have served their purpose they will be have to be taken down, cleaned and prepared in time for next year!

Common bird monitoring in Cabrera National Park

During the last few days the spring census of common birds in the Cabrera National Park has been taking place.

NHS collaborates with the Sociedad Española de Ornitología (SEO-Birdlife) by undertaking transects and listening points to be able to detect spring breeding species and obtain distribution and abundance results.
The tasks are carried out on the island of Cabrera Gran, and at the moment the species with the largest distribution is the Balearic Warbler (S.balearica).
