After two sparse years, we have some birds at the feeders. More than that since we see birds zooming in and out of the spruce trees and I have also seen bugs in the same place so I'll presume they are eating bugs. I did see one pick up a bug from the flower garden.
I read in this thread somewhere that most of their diet is bugs, and the feeders are more used in summer when flowers and bugs aren't as lush.
Also, we saw a bird go up to an alcove on the patio where we had a feeder last year but none yet this year. There is no reason for that bird to go where it was so I'll presume it is a returning bird that had been to that feeder last year. We also had that happen in prior years and I feel certain it is the returning birds.
Anyway, birds are cyclical in volume and we appear to be on the upswing. The wife changes the food every few days when it's warm and the birds seem to like the fresh food. We re hoping for a good summer of birds.
