Notes:  Three visits this week yielded some very interesting observations.  On each occasion, a Rusty Blackbird was observed near the feeders, likely the same individual first spotted on December 11.  It appears to favour the millet in the mix provided on the platform feeder.  On Wednesday there was also a Red-winged Blackbird, and the first sighting of a White-throated Sparrow at the feeders since early November.  The same day, a walk of the census loop produced the winterís first Brown Creeper in the back woods.  Aside from it, a few Black-capped Chickadees, and a flock of European Starlings, all other birds observed were in the vicinity of the feeders.  No deer have been seen for many weeks, but now that there is snow cover, their tracks are visible and it is evident that they are using the site heavily, and in many cases following our trails.
