Nesting
Around at the end of March, the tarins leave their retirements of winter, and turn over in the surfaces of nesting. The Nid is generally built on the end of a branch in the Cime of a Conifère, often with more than 20 meters height. The nest consists of Radicelle S, of Crin, Plume S and sleeping bag finely braided by the adults. Once the nest completed the female lays from 4 to 6 mottled eggs blue pale the russet-red one and of a size of approximately 15-19 mm X 11-13 mm, which it only will brood during a little less than one week.Breeding of let us oisillons
