Feeding and breeding ecology of three insectivorous birds in Mediterranean ecosystems

2009

Tits (Paridae) are one of the most and better passerines known owing to they are broadly distributed, breeding in different habitats from gardens to forests, and they make use of nest boxes for breeding. Hence, such species are ideal for comparative studies on a large geographical scale. Despite the great amount of information concerned to tits, we still do not really understand life-history strategies of birds living under most ecological conditions. The present thesis is focused on achieving a better understanding of how birds are adapted to their environment. In particular, to examine the existence and the consequences of food limitation in Mediterranean evergreen habitats, through an ad…
