Wow. I don't see hummers my way until around Mother's Day/Memorial Day, and they're usually gone by mid September. I usually only have 3 hummers, 2 females & 1 male (I know 2 different females as I've seen both at the same time .. one sipping on the feeder, 1 sipping on an agastache). My mom who lives in the mountains of S. NM has hummers by the score (seriously.. I kid you not. I've actually got bad video of it.. it's pretty amazing). I remember as a kid having to fill all 8 2-liter feeders twice a day.. damn birds would be SOO impatient as I was filling them up. Then as I would be re-hanging them they'd sit on my thumb/fingers and drink as I was lifting the feeders back onto the nails! Pretty funny stuff. Also learned never to wear red outside.. nope, not if I didn't want to be divebombed constantly. She has Broadtails, Ruby Throated, Annas, Rufus (my favorites), & Calliopes. Calliopes are SOOOOOOOOOO cute.. so teeny! Rufus are the meanest.. they would bully EVERYONE away. I miss having tons of hummers... Y'all who can have 'em year 'round are so lucky...
