The passage of several hundred Redwing through
Camrose in the last few weeks has provided a second year of good biometric
data. 50/50 - Adults/Juveniles. Give the migrating distances involved, we noted
several birds in the 70g bracket, several topping 75g and one at 82.2g, the
average weight of a Redwing is 65g. The average wing as per BTO data is 119mm
and the majority were just that or 1mm -/+, however, some birds were measuring
well into the 120’s with one topping 129mm. A calm early morning seems the ideal
time but to find one in November and December is an endeavour, to collect this
very ‘time specific’ data.
