Yeah that kind of stuff happens all the time at my dads house, they feed the hummers, and after 15 years of feeding them they have a lot of them every year.. They have eight feeders that they fill twice a day,, a total of 2 gallons of hummer juice each day!!! they would eat more but my dad says that hes not giving them any more than that. You can sit and watch literally 30-40 on the feeders at one time, any time your in the yard they dive bomb us and fly all around checking stuff out,, its crazy, you dont want to wear bright colors,, bright stuff seems to attract them even more.
