01/09/2012 This morning's visit was the last CES session of the year. The highlight of the morning was our first blackcap of the year weighing 20 grams or over - always a good indication that the autumn migration is well underway. Y103813 weighed in at 23.1 grams.

Today's totals (ringed and retraps) were:
