I have been given several diffferent opinions about when we should take our hummingbird feeders down. Can someone give me an approximate date that we should? I was always told Sept 15th, then someone said they wait till Oct 1st to give those hummers from up north a chance to stop by and get some nourishment on their way south. That sounds logical.. any other ideas?? I still have alot at my feeder for now. A friend of mine about a mile away, who knows her birds, told me that she had a male hummer that only had a black throat, not a bit of red on it. Is there another one around other than our Ruby Throated? Thanks.. debi lucas Greenup Co.
