This Blue Jay 'want-to-be' provided for some enjoyable
observations, as black oil sunflower
and nyjer seed are apparently much easier for Black-capped
Chickadees to obtain than
shelled peanuts.

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.
