Absolutely fantastic, Birdie! The hummer is delightful (perfect light, pose, post, etc) but the bee is stupendous! I would have thought 1/1600 would be way too slow...you must be the bee-whisperer!
Awesome photos, Roberta! WOW! It's one thing to get an amazing photo of a hummer at a feeder but to manage to get a stunning shot like this with one at a flower - that's just amazing! The bee and the dragonfly are also jaw-dropping! Bravo!
Holy Smokes! Are you shooting with the Hubble?!! Shots like these make us all want to be out there with our cameras (not that we'll do as well as you ... ) and Thank You!!
