Authors(s) and Affiliation(s)



The breeding biology and demography of Blue tit (Parus caerulens) and coal tit (Parus ater) populations of southern France and Corsica were compared from 1976 to 1980. The following differences were found: 1. the onset of the breeding season is delayed in Corsica| 2. the clutch-size is smaller on the island| 3. the mortality of the nestlings is also much higher in Corsica| 4. however, the survival rate of adult tits is higher in Corsica than on the mainland| 5. contrary to what is the rule in southern France, Corsican tits do not apparently breed at the time of maximum food abundance. The demographic strategies of the Corsican populations of Blue and Coal tits are apparently K-selected.
