We have Hummingbirds come to our feeders every year. These are a couple from last year, they usually return in May around the 13th - 15th. I'm looking forward to seeing them again.
The top photo is one of the male, the middle one is the female and the bottom one is the male again. Come September when their chicks have flown the nest, they too will come to the feeders. The parents though become aggressive towards their young and will try driving them off, I guess it's a case of you're on your own now kid.
