The local population had significantly shorter wings, and longer tails and tarsi than the wintering population. In both populations, juveniles had shorter wings and longer tails than adults, but tarsus length did not differ between age classes. Among the local birds, males had longer wings and tails than females, but tarsus length did not differ between sexes (sex could not be determined in the wintering population). Biometric analyses supported the hypothesis of the occurrence of two separate populations in the study area, and also that the migratory tendency (as derived from wing and tail lengths) was higher among the wintering birds.</style></abstract></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%">Dominguez, Monica</style></author><author><style face="normal" font="default" size="100%">Barba, Emilio</style></author><author><style face="normal" font="default" size="100%">Canto, Jose L.</style></author><author><style face="normal" font="default" size="100%">Lopez, German M.</style></author><author><style face="normal" font="default" size="100%">Monros, Juan S.</style></author></authors></contributors><titles><title><style face="normal" font="default" size="100%">Seasonal interchange of the European Robin Erithacus rubecula populations in an evergreen holm oak forest</style></title><secondary-title><style face="normal" font="default" size="100%">ACTA ORNITHOLOGICA</style></secondary-title></titles><keywords><keyword><style  face="normal" font="default" size="100%">biometry</style></keyword><keyword><style  face="normal" font="default" size="100%">Erithacus rubecula</style></keyword><keyword><style  face="normal" font="default" size="100%">European Robin</style></keyword><keyword><style  face="normal" font="default" size="100%">flight-related morphology</style></keyword><keyword><style  face="normal" font="default" size="100%">migratory tendency</style></keyword><keyword><style  face="normal" font="default" size="100%">population replacement</style></keyword><keyword><style  face="normal" font="default" size="100%">wintering quarters</style></keyword></keywords><dates><year><style  face="normal" font="default" size="100%">2007</style></year><pub-dates><date><style  face="normal" font="default" size="100%">2007///</style></date></pub-dates></dates><volume><style face="normal" font="default" size="100%">42</style></volume><pages><style face="normal" font="default" size="100%">15 - 21</style></pages><language><style face="normal" font="default" size="100%">eng</style></language><abstract><style face="normal" font="default" size="100%">European Robins are found at ``La Font Roja{''} Natural Park in SE Spain throughout the year.

All sites were placed at about the same latitude (39-41°N), and all were studied during the same years (1992-95). Our results show that (1) laying date did not differ between the natural habitats at the same altitude (range of the means of yearly means 4-8 May); (2) within the same habitat type (holm oak forest) laying date was earlier at low altitude (30 April vs. 8 May); (3) laying date was earlier in the orange plantations (21 April) than in natural habitats; (4) among natural habitats at the same altitude, clutch size decreased from zeen oak (mean of yearly means 7.3 eggs) to holm oak (7.0 eggs) to pine forests (6.4 eggs), though only the difference between zeen oak and pine forests was significant; (5) within the same habitat type (holm oak forest), the clutch size tended to be larger at high altitude (7.0 vs. 5.9 eggs); and (6) clutch size in orange plantations (7.7 eggs) did not differ significantly from that of the zeen oak forest, but was larger than in the holm oak and pine forests. We discuss the effect of the habitat type on laying date and clutch size of Great Tits.</style></abstract></record></records></xml>
