My Mom got these two last Christmas as a gift. She has a doublke shepards hook that the maintence man where she lives put up for her and filled the regular bird feeder. I guess as soon as he walked away the birds found it and she has a lovely view of al these birds right outside her living room window. My question is is it OK for her to use the other side of the shepards hook to hang the hummingbird feeder? Are the birds compatible oin the same space. I'm sure I'm not asking that right. I guess what I'm asking is whether or not hummingbirds want thier privacy.
