Bird Feeders and Baths are suddenly empty

Thank you very much for the information about the Hawk's scaring away all the other birds. We had birds all day long and now can not see or hear a bird due to Hawk's flying and landing low. We also had seven different species of Hummingbirds and now only have two feeding for the last three days. Our Ruby-throated even disappeared, which really shocked us, as he was so terratorial about the feeder. I believed the disappearance was due to the Hawk's but actually seeing it on this sight helps me to know why all my feathered friends have gone away and I also saw where hopefully they will be back when the Hawk's disappear. Thank you all for the great info and a great site. Sincerely, Shelly
