Subject: Re: feeder density question
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.
