How cool about the hummingbirds!
They could be siblings. I don't really know when they would get along. Maybe if they are females, too?
Either way, it's adorable to have so many, and especially to have them come to the patio. They must have connected you coming out to refill the feeders with eating. Smart little cookies!
Thank you for the fun news.
