I have noticed much less (in fact, only a few) small birds coming to my feeder this winter. It is not just visual observation, which could be misleading. Last year I run out of organic seeds I always buy for my birds and had difficulty to buy some more later in the season. So, at the beginning of this winter I bought as much as I usually needed for the whole feeding period. Looks like, I will be left with most of the seeds when the spring comes. I would appreciate to hear from other people on the forum about their observations.
