I have noted the same. In addition, the species are somewhat different. For example, we have numerous flickers but no tree sparrows. Tree sparrows ( as well as white crowns) were common at our feeders in the winter 20 years ago but have steadily decreased in recent years. Habitat is still quite good so I don't think the observation is due to habitat loss. I feel sure that climate change is playing a role but teasing apart just what is going on will take some good science.
