Ringing recoveries of Razorbills Alca torda and Guillemots Uria aalge in Danish waters
Lyngs, P. & Kampp, K. (1996) Dansk Orn. Foren. Tidsskr. 90:119-132
Several hundred thousand Razorbills Alca torda and Guillemots Uria aalge have been reported to frequent the seas around Denmark in recent years. Between 200000 and 400000 Razorbills were estimated in the winters 1987 and 1988, and 200 000 Guillemots moulted in the Skagerrak during late summer, with peak numbers in late autumn being about 300 000 (Jensen 1993, Durinck et al. 1994, Skov et al. 1995). Danish waters are thus of international importance for these auks. Since a full evaluation of this importance requires that the populations and age-classes involved are known we here analyse the ringing recoveries of Razorbills and Guillemots in Denmark.
