We fitted 117 European Robins with radio transmitters (Table 1).
In 2002, most European Robins were radio-tagged on the 1st day of a migration wave (n = 37), while others were radio-tagged upon recapture on the 2nd or 3rd day after their initial banding (n = 13).
2003) used linear regression of body mass on wing length to calculate lean body mass of European Robins that had no visible subcutaneous fat (fat score 0, after Kaiser 1993); they made separate calculations for September, October (fall) and April (spring).
Telemetry protocol--We radio-tagged European Robins with LB-2 transmitters (Holohil Systems, Carp, Ontario, Canada).
The stopover duration of European Robins during spring migration varied from 1 to 12 days (Fig.
The movements of European Robins that remained for several days showed varying patterns.
