Mean clutch sizes were 3.71 on Bird Island and 3.76 on Black Rock in 1993, and 3.4 on Bird Island in 1994. Total productivity on Bird Island in 1993 was calculated as 1.79 young fledged per nesting attempt. Reproductive success was measured on Bird Island in 1993 using data collected from 121 marked nests, and included clutch size, the number of eggs hatched and the number of young fledged. These data were related to the timing of nesting and the position of the nest within the colony. Early nests tended to be located more centrally in the colony than later nests, which were progressively further from the centre. There was a progressive decline in mean values for each reproductive parameter between early and late nesting birds and with increasing distance from the colony centre.","AbstractOtherLang":"Het broedsucces van de Aalscholver <i>Phalacrocorax carbo</i> werd onderzocht op twee kleine eilandjes in Strangford Lough, Noord-Ierland, in 1993 en 1994. De gemiddelde legselgrootte was 3.71 op Bird Island en 3.76 op Black Rock in 1993 en 3.4 op Bird Island in 1994. Het broedsuccess op Bird Island werd geschat op 1.79 uitgevlogen jongen per broedpoging. Het broedsucces werd bepaald in 121 gemerkte nesten en kon vervolgens worden gerelateerd aan het tijdstip van nestbouw en eileg en aan de positie in de kolonie. 'Vroege' legsels werden vooral in de buurt van het centrum van de kolonie aangetroffen, laterer legsels vooral aan de randen. Berekend vanuit het centrum van de kolonie werd een gestage afname in broedsucces gevonden bij een toenemende afstand tot het centrum van de kolonie.","BibLvlCode":"AS","StandardTitle":"Reproductive success in the Great Cormorant <i>Phalacrocorax carbo carbo</i> in relation to colony nest position and timing of nesting = Broedsucces bij de Aalscholver in relatie met de positie van het nest en het tijdstip van broeden","OrigTitleLangCode":"en","OrigTitleLangCodeExtended":"eng","OrigTitleLangID":15,"DateLastModified":{"date":"2024-12-10 01:33:17.368041","timezone_type":1,"timezone":"+01:00"},"UserAccessRight":null,"UserAccID":null,"AuthorKeywords":null,"OtherDescriptors":null,"Notes":null,"AnaPub":1999,"MonPub":null,"DateUpdate":"2017-09-05","DateCreate":"2001-02-21","SecASFANote":null,"ConfID":null,"PeerRev":1,"VlizCoreFlag":1,"WoScode":null,"VABBcode":null,"OpenAcc":1},"refs":null,"anarec":{"AnaID":6247,"PubliDate":1999,"Pagination":"107-120","XtraPublOfAnaID":null,"ISBN":null,"Volume":"1","Issue":"3","BRefMon":null,"BRefMonRR":null,"BRefXtra":null,"BRefXtraRR":null,"SerBRefID":45223,"SerRR":"Atlantic Seabirds.
