Short abstract from the book:
(89 %) af fuglene er genfundet langs Jyllands vestkyst, men enkelte fugle er fundet langs Jyllands østkyst og i de indre danske farvande (fig. 1). I efterårsperioder med frisk pålandsvind er på en enkelt dag registreret op til 3.700 suler ved Blåvands Huk (Jakobsen in press). Genfundene antyder, at disse fugle stammer fra alle de europæiske kolonier, inklusive Irland og Island. De ringmærkede suler er fundet i perioden 1938 til 2001, flest i 1989 hvor der blev fundet seks. Af de genfundne fugle var 14 % i deres første leveår, 34 % i andet og 14 % i tredje. Sulerne kan som andre havfuglearter blive ganske gamle. Den ældste ringmærkede sule, der er fundet i Danmark, var ringmærket i Skotland hele 31 år og 3 mdr. forinden. English summary The gannet is a fairly common migrant on the Danish west coast, mainly in periods with westerly winds. Twenty gannets have been ringed in Denmark, mainly weakened birds released after rearing. One ringed bird was later reported from Friesland in the Netherlands and three were found close to the ringing site. In Denmark, 110 foreign-ringed gannets have been recovered. These were ringed in colonies on the Faeroe Islands, Iceland, Lofoten, Great Britain and the Netherlands. The gannets were recovered at all times of the year, most in October, and mainly (89 %) along the Danish west coast. Fourteen per cent of the recovered birds were recovered in their first year, 34 % in their second year and 14 % in their third. The oldest gannet recovered in Denmark was aged 31 years and 3 months.
