Our hummingbird feeder has been out for about 2 weeks now and I have never filled it back up so many times!!! I filled it up this morning and again at about 2:30 and now it is about half gone already. I have seen four feeding at the same time and they hover around and never go too far away from the feeder. If you have ever sat and watched hummingbirds, you know that they are vicious little creatures - dive bombing each other and chasing each other away from the feeder. I know I will find one dead one morning having been impaled by those long sharp beaks. But they are fun to watch and thank goodness it doesn't cost much to feed them - just some water and sugar.
