Ours have been gone for a week - we have had 4 feeders up and filled them up almost every day for the past month or so. Seems that the hummers were a little slow/late in coming this year - but when they did - WOW - we would go outside with a newly filled feeder and just hold it up and we would be swarmed with birds eating basically from our hands. One hummer sat on my thumb while I was holding the feeder - so neat!!!!! We are in southern MO>
