Abstract
Zviždak (Phylloscopus collybita) i brezov zviždak (Phylloscopus trochilus) dvije su srodne vrste malih pjevica, čiji areal rasprostranjenosti obuhvaća većinu europskog kontinenta i dio Azije. Tijekom proljetne i jesenske selidbe sjevernoeuropske populacije obje vrste koriste dio selidbenog puta koji prati obalu Baltičkog mora. S obzirom da spolove ovih vrsta nije moguće razlikovati na temelju obojenosti njihova perja, spolno specifične selidbene strategije ovih populacija do sada nisu detaljno istraživane. U sklopu ovog istraživanja sakupljala sam uzorke krvi zviždaka i brezovih zviždaka za vrijeme njihove selidbe kroz sjevernu Poljsku, kako bih im genetički odredila spol. Dobivene podatke o spolu sam iskoristila za morfološke usporedbe muških i ženskih jedinki, te uspostavljanje kriterija za morfološko određivanje spola. Pomoću tako uspostavljenog kriterija sam zatim odredila spol jedinkama ulovljenim tijekom ranijih proljetnih sezona migracije. Analiza tempiranja selidbe pokazala je da mužjaci obje vrste stižu na područje gniježđenja prije ženki. Raspored selidbe zviždka podložniji je utjecaju temperature i zamjetno više varira iz godine u godinu nego raspored selidbe brezovog zviždka.
Abstract (english)
Chiffchaff (Phylloscopus collybita) and Willow Warbler (Phylloscopus trochilus) are two sympatric bird species breeding across most of Europe and a part of Asia. During autumn and spring migration to Africa and southern parts of Europe, north-European populations of these species migrate along the coasts of the Baltic Sea. Both species are monomorphic in plumage, which impedes any research of potential sex differences in their migration behaviour. I collected and analysed blood samples of individuals of both species captured during their migration through the Baltic coast in northern Poland, to determine their sex genetically, by DNA from blood and feather samples. Based on the measurements of DNA-sexed individuals, I developed criteria for morphological sexing of each species. I applied these criteria to sex unsampled birds captured at the same ringing site during several migration seasons in the past, to identify sex differences in their migration timing and the effects of weather on migration. Differential migration in the form of protandry was revealed in both species. The timing of males' passage varied considerably from year to year in Chiffchaff, but less so in Willow Warbler, pointing to a more rigid migration schedule in the latter species. Additionally, temperature appears to influence migration timing and choice of stopover in Chiffchaffs.
