We tried the hummingbird feeder one time. I don’t think we got any because hummingbirds are pretty sparse in our colder part of the country. Seems to work better in places like Southern California.
Regarding bird feeders, they generally turn into squirrel feeders where I live. Which I wouldn’t mind as I like squirrels and think they are cute, but based on their chubbiness they find quite enough to eat around town and in the trees full of acorns, mulberries, crabapples etc without my making a restaurant for them.
Also, if you live near any woods, bird feeders can attract bears, which creates a risk for the residents and the bear.
