For the past several weeks, hummingbird fanciers have enjoyed watching squadrons of ruby-throated hummingbirds displaying their aeronautical skills in backyards across the state. These tiny dynamos have been flying between feeders and flowers, gorging themselves on sugar water and nectar. When they haven't been feeding, they seem to have been trying to keep others from enjoying the sweet bounty.
While we find their activities entertaining, to hummingbirds it is a matter of life and death.
