Notes:  Not much to comment on this week - it was another dismally wet period, and attempts at banding were again washed out.  A few more species were added to this year's winter list, namely Ring-billed Gull, Rock Pigeon, and Common Raven.  Activity at the feeders is gradually picking up, though it still seems quieter than at this time in 2004 and 2005 (but that may be due to it being warmer and rainier than in those years).
