Choosing a hummingbird feeder can be somewhat challenging the wish to have something that is attractive for you and for your yard can lead to you to the wrong feeder. For example feeders that have a metal base where the birds put their beaks are not good for the birds. They are also less attractive to the hummingbirds. And possible the worst thing about metal feeders are hard to clean and just generally not a good choice however they tend to be the prettier ones.
