Boz330 has a similar horde in his back yard. His wife puts out several feeders and sometimes has to fill some of them twice a day.
It's impossible to get an accurate count, but at any one time there may be 50 or so on the feeders or waiting their turn to get a drink.
They have one bully that spends all his time chasing the other birds off his personal feeder.
Fascinating little creatures.
