The population was relatively stable around 20 pairs until the mid-1980s after which it increased markedly. Mean laying date was advanced by almost 5 days over the 60-year period, with most of the change taking place after 1985. The mean size of first clutches was 8.72 and was negatively related to number of breeding pairs. Mainly because of Pine Marten Martes martes predation, the mean number of fledged young was only 5.76 (all nests) and 7.37 (nests with at least one fledgling). The proportion of second clutches varied from zero to c.20%. Second clutches had a mean size of 7.00 eggs, slightly less than that of replacement clutches (7.29). The mean number of young fledging from these two categories of broods combined was 5.5. Both the clutch size and fledging success found in this study are similar to those in other Swedish studies at similar latitudes.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69761685","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Counts across all staging sites yielded 2,700–3,700 geese in southern Västerbotten and 4,000–4,800 at all sites in Västerbotten and Norrbotten. We estimate that 5,000–6,000 geese currently use the Western Flyway. Migration along the Central Flyway (Ostrobothnia, Finland) culminated on average about ten days earlier, meaning that the vast majority of geese using this flyway had left southern Sweden when the Western Flyway was activated. Counts of active migration on 15 April 2007 indicated that geese arriving in the Ume River Delta in late afternoon had passed Alirs öga, Söderhamn, 340 km to the south, five hours earlier. Assuming the same ground speed (68 km h-1) south of Söderhamn, these geese ought to have left either Lake Östen and/or Lake Kvismaren at sunrise, reaching the staging sites in Västerbotten after a 600–700 km non-stop flight.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69761970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Over the past 30 years more species have decreased (38%) than increased (32%) in numbers. In particular, formerly common farmland species have fared poorly but this is also true for some forest species. Over the past 10 years there are more species with increasing trends (29%) than there are species with decreasing trends (19%). Trends for several species in long-term decline have levelled off and have in some cases even started to increase. It is not known whether this recent change is a result of conservation efforts or simply that population numbers have stabilised at lower levels now permitted by the environment. It is therefore essential to initiate research devoted to finding factors directly linked to ongoing population changes, particularly for species in long-term decline. To cover population trends for all Swedish species additional monitoring programmes are needed, in particular on owls and in mountain habitats.","PeriodicalId":52418,"journal":{"name":"Ornis Svecica","volume":"1 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2009-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"69761248","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
