I don't think so. Maybe why they decided to hang around a bit. I have so dang blasted many english sparrows. Lots of white crown ones as well, that I don't even bother with the feed. I have alot of natural stuff. I put up a hummingbird feeder for the Mrs, for mothers day right outside her kitchen window. ALready had a visitor. We don't have many though, but as the lilacs mature and alot of my other stuff, I bet we get more. I understand my ex-Mother-in-law was just in Birds and Blooms with an article on hummers. She used to get TONS. They are in Inchelium, over on the Rez, South of Colville. They used to buzz like skeeters. There would be thirty at atime looking for a sip of nectar. I miss that. We used to have several nesting pairs in Twisp that we would watch. I hope I cna have a couple around this year.
