Every year I set up a couple of hummingbird feeders in my backyard. In northern Illinois, the Ruby Throated Hummingbird is primarily the only species that migrates to our area. This little bird averages 3″ to 4″ in size and can beat its wings 53 times per second. They are very fun to watch. The males are extremely territorial. They will dive bomb and give chase to an intruder to send him on his way.
This male hummingbird below would sit at the feeder for hours into the night to guard its territory.
