We have alot of 'em around the house this year. Man they are some mean little suckers! dont know if its a territorial thing or what but they chase each other off the feeders with ferocity! Females seem to be more aggresive than the males. Saw 3 females at one of the feeders this morning but that only lasted a second or two before a forth one dive bombed in and they scattered. Think that one was a male. Wish i couldve snapped a picture, cool little birds and entertaining to sit and watch buzzing among the flowers. They are chatty little birds, too.
