Observer:  Shawn Craik

Notes:  Another winter week has passed with no banding information to share.  However, seasonally warm temperatures are predicted to continue so we hope to try banding later this week.  Observation highlights included a flock of 13 Canada Geese flying low over the corn field on Thursday.  This is an interesting sighting given that nearby Lac St-Louis has been frozen for over a month and that current snow cover in the field would restrict feeding of geese on waste grain.  It marks the first February record of Canada Goose at MBO.  Feeder activity was dominated by American Tree Sparrows, Black-capped Chickadees, Slate-coloured Juncos, and Mourning Doves.  The flock (>15 birds) of House Finches remained in the area.
