American Robins are still present in large numbers daily, no
doubt in large part due to
the rich crop of buckthorn berries across much of the site. (Photo by

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).
