The date of the first encounter of eggs in the nest is noted.\r\nThe nests are marked with a (bamboo) stick and a label containing the nest number. The eggs are marked using permeable inkt by writing the egg and nest number on the top of each egg. This makes it possible to determine afterwards wheter an egg has hatched or has been predated.\r\nThe marked nests are checked at regular time intervals. All possible information on the fate of the eggs is noted. This way it is possible to keep track of the eggs and nests and to determine things like hatching and breeding succes of the marked nests. \r\nChick weight is measured with an electronic balance to a precision of 1 g. Egg size, total head length and stretched wing chord is measured using a calliper with precision of 0,1 mm.\r\nAt certain locations enclosures are placed around concentrations of marked nests. This method is applied to keep the chicks of semi-nest leavers on a fixed location so they can be easily observed and retrieved until the moment of flying out.\r\nAn enclosure is a fence of chicken wire (+/-50 cm height) that is attached to wooden bars surrounding a number of nests. At the bottom of the fence at the inside of the enclosure a folio (20cm height) is attached to prevent the chicks from damaging theirselfs. The chicken wire has to be doug into the ground for a few centimeters to prevent the chicks to escape.\r\nMaximum once in the 2 or 3 days and minimum once a week, the chicks in the enclosures are checked. Chicks that are over 20 days old at the moment of checking and that have dissapeared from the enclosure, are considered to have flown out. If they are already missing at an earlier age, they are noted as ‘disappeared’. In most cases this means they have been predated.\r\nThe enclosure method is applied in several European colonies and this makes the data immediately comparable.","OrigAbstract":"Dataset als resultaat van het bepalen van broedsucces en biometrie van eieren en kuikens binnen  30 tot 40 afgebakende nesten (kippegaas 50 cm hoogte) in de voorhaven van Zeebrugge.","OrigDescr":"Vanaf het moment dat de vogels regelmatig op de broedplaatsen gaan neerzitten en het maken van nestkuiltjes wordt vastgesteld, worden de broedterreinen in Zeebrugge regelmatig gecontroleerd op de aanwezigheid van eieren. De datum waarop de eieren voor het eerst worden aangetroffen in het nest wordt genoteerd.\r\nDe nesten worden gemarkeerd met een (bamboe-) stok waaraan een etiket hangt met het nestnummer. Met onuitwisbare inkt worden de eieren gemarkeerd door op de top van elk ei het ei- en/of nestnummer te schrijven, zodat nadien bepaald kan worden welk ei gepredeerd of uitgekomen is.\r\nDe gemarkeerde nesten worden op regelmatige tijdstippen gecontroleerd. Alle mogelijk informatie over het lot van de eieren wordt genoteerd. Op die manier is het mogelijk om de eieren en nesten te blijven volgen en zo zaken zoals het uitkomst- en broedsucces van de gemarkeerde nesten te bepalen.\r\nHet gewicht van de jongen wordt gemeten met een electronische balans met een precisie van 1 g. De grootte van de eieren, de totale koplengte en gestrekte vleugelbreedte wordt gemeten met behulp van een schuifpasser met precisie van 0,1 mm.\r\nOp bepaalde locaties worden enclosures geplaatst rondom concentraties van gemarkeerde nesten. Deze methode wordt toegepast om de jongen van semi-nestvlieders op een vaste locatie te houden zodat ze tot het uitvliegen teruggevonden en gemakkelijk geobserveerd kunnen worden. Een enclosure bestaat uit het plaatsen van kippengaas, van ongeveer 50 cm hoog, vastgemaakt aan houten palen, rondom een aantal nesten. Onderaan het gaas wordt aan de binnenzijde damp-schermfolie bevestigd van 20 cm hoogte om te voorkomen dat kuikens zich zouden beschadigen aan het gaas. Het kippegaas dient enkele cm ingegraven te zijn om te vermijden dat kuikens ontsnappen. Maximaal éénmaal per 2 à 3 dagen en minimaal éénmaal per week worden de kuikens in de enclosures gecontroleerd. Jongen die bij controle op een leeftijd van 20 dagen of ouder zijn verdwenen, worden als uitgevlogen beschouwd, indien ze op jongere leeftijd niet meer worden teruggevonden, worden ze als verdwenen genoteerd. In de meeste gevallen betekend dit dat ze gepredeerd zijn. De enclosuremethode wordt in meerdere Europese kolonies gebruikt en de gegevens zijn direct vergelijkbaar.","Comments":null,"ReleaseDate":null,"ReleaseDate0":null,"OrigDescrLang":"Dutch","EmbargoDate":null,"OrigDescrLangNL":"Nederlands","OrigLangCode":"nl","OrigLangCodeExtended":"dut","OrigLangID":41,"DescrCompFlag":1,"DescrTransFlag":1,"Citation":"Data Institute for Nature Conservation","AccessConstraints":null,"UDate":"2010-11-05","CDate":"2004-05-10","CurrencyDate":"Jan 26 2004 12:00AM","RevisionDate":"Jan 26 2004 12:00AM","DateLastModified":{"date":"2026-04-10 01:42:12.540544","timezone_type":1,"timezone":"+02:00"},"CheckedFlag":1,"PublicFlag":1,"VlizCoreFlag":1,"MarineFlag":1,"FreshFlag":null,"BrackishFlag":null,"TerrestrialFlag":1,"StatusID":1,"DasType":"Data","DasTypeID":1,"DasOrigin":"Research","Progress":"Completed","AccessConstraint":"Unrestricted after moratorium period","AccConstrEN":"Unrestricted after moratorium period","AccConstrDisplay":null,"License":null,"AccConstrDescription":"Data are initially restricted, but the access condition relaxes to academic or unrestricted once a specified period of time after an event (such as collection, publication, completion of QC procedures or project cessation) has elapsed","Lineage":null,"AccConID":8},"dois":null,"spcols":[{"SpColID":131,"SpName":"Belgian marine datasets"}],"keywords":[{"ThesaurusTerm":"Birds","ThesTypID":2,"ThesType":"CSA Technology Research Database Master Thesaurus","Code":null,"Description":null,"OrigThesTerm":"Birds","DutchTerm":"Vogels","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Birds (marine)","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":null,"Description":null,"OrigThesTerm":"Birds (marine)","DutchTerm":"Zeevogels","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Breeding birds","ThesTypID":0,"ThesType":null,"Code":null,"Description":null,"OrigThesTerm":"Breeding birds","DutchTerm":"Broedvogels","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Breeding success","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":null,"Description":null,"OrigThesTerm":"Breeding success","DutchTerm":"Broedsucces","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Clutch size","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":null,"Description":null,"OrigThesTerm":"Clutch size","DutchTerm":"Leg grootte","URI":null,"DasKeywordDescr":null},{"ThesaurusTerm":"Stock assessment","ThesTypID":1,"ThesType":"ASFA Thesaurus List","Code":"c_24251","Description":null,"OrigThesTerm":"Stock assessment","DutchTerm":"Evaluatie van stocks","URI":"http://aims.fao.org/aos/agrovoc/c_24251","DasKeywordDescr":null}],"parents":[{"DasID":35,"Acronym":null,"EngAbstract":"In Zeebrugge, the population size, population structure and breeding succes () was determined for coastal breeders.","License":null,"StandardTitle":"Evolution of populations of coastal breeders at the inner port of Zeebrugge","doi":null,"vlizDoi":null}],"children":[{"DasID":148,"Acronym":null,"EngAbstract":"The weight of chicks of coastal breeders in Zeebrugge is measured with an electronic balance to a precision of 1 g.
