The hummingbirds are going nuts at my house. There's at least ten that fight over this feeder and I get hardly any business at the THREE other feeders I have hanging in the yard. There is also one hornet that has been hogging this feeder all day. You can kind of see him in the video if you look. He thinks he's really tough because he chases the birds away but he better watch it because sometimes I find hornet corpses in the nectar and I suspect that the hummingbirds wait until just the right moment and poke them into the holes with their pointy beaks when they get the chance. Watch it, you asshole hornet, or I will be fishing your dismembered corpse out of a nectary grave.
