PERDECK AC (1963) Annual Report of the Vogeltrekstation for 1962. LIMOSA 36 (3): 129-137.
The displacement experiment with Starlings to Spain was closed with the transport
of 1100 birds. Attention is drawn to the recoveries of adult birds, showing a clear
tendency to fly back to the original winterquarter (fig. 1, dots). The recoveries of
juveniles in late winter and spring indicate that spring migration is directed to ENE.
This point to a parallel course to the original migration route in stead of a homing
tendency.
On the fowling-yard near The Hague nearly 5500 birds were ringed. One Arctic
Redpoll (Carduelis hornemanni) was caught (Nov. 6th).
Under the Dutch ringing scheme at least 70000 birds were ringed and 3200
recoveries obtained.
Observations on the standard direction of the Scandinavian chaffinch were continued
in Norway. At a suitable point near Kristiansand seaward migration in predominantly
S by W direction was observed (fig. 2). Near Oslo broad front migration was observed
mainly in the directions S by Wand SSW. There is no doubt that the standard
direction in Scandinavia is about Sby W.
All directions observed up till now are shown in fig. 3.
