In different years the density in two plots without nest-boxes varied between 1.0 and 6.5 pairs per 10 ha. Nestbox introduction seems to have increased the density of breeding pairs. The mean laying date was earlier (6 vs. 13 May) in low altitude (500-750 m a.s.l.) plots than in a high altitude (900-1000) m a.s.l.) plot, but clutch size (6.9 vs. 6.5 eggs) was not significantly different (mean 6.6 eggs). No differences in mean laying dates were found between years. Significant differences in clutch size were found only between two years at the high altitude site. There was a slight, non-significant, seasonal decline in clutch size. No second clutches were laid. These results are discussed in the context of other Mediterranean studies with special focus on the differences and similarities between Corsican and mainland populations. It is shown that most of the characteristics of the Corsican population (i.e. density, habitat use, laying date, clutch size, number of broods per year) are shared by some populations on the mainland. On the other hand, some breeding traits of Blue Tit populations in southern France are closer to those of Central and North European populations than to the Iberian ones.</style></abstract><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></record><record><source-app name="Biblio" version="7.x">Drupal-Biblio</source-app><ref-type>17</ref-type><contributors><authors><author><style face="normal" font="default" size="100%">ISENMANN, P</style></author><author><style face="normal" font="default" size="100%">ALES, E</style></author><author><style face="normal" font="default" size="100%">MORENO, O</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">THE TIMING OF BREEDING AND CLUTCH SIZE OF BLUE TITS (PARUS-CAERULEUS) IN AN EVERGREEN HOLM OAK HABITAT IN SOUTHERN SPAIN</style></title><secondary-title><style face="normal" font="default" size="100%">REVUE D ECOLOGIE-LA TERRE ET LA VIE</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">blur tits</style></keyword><keyword><style  face="normal" font="default" size="100%">clutch size</style></keyword><keyword><style  face="normal" font="default" size="100%">Holm oak</style></keyword><keyword><style  face="normal" font="default" size="100%">Parus cearuleus</style></keyword><keyword><style  face="normal" font="default" size="100%">Spain</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">1990</style></year></dates><publisher><style face="normal" font="default" size="100%">SOC NATL PROTECTION NATURE ACCLIMATATION FRANCE</style></publisher><pub-location><style face="normal" font="default" size="100%">57 RUE CUVIER, 75005 PARIS 5, FRANCE</style></pub-location><volume><style face="normal" font="default" size="100%">45</style></volume><pages><style face="normal" font="default" size="100%">177-181</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><notes><style face="normal" font="default" size="100%">APS</style></notes><research-notes><style face="normal" font="default" size="100%">APS</style></research-notes></record></records></xml>
