I love humming birds I have a lot of them around here, I used to keep a feeder up in front of my window for them they still come back and check to see if I put it back up yet. I had to take it down it was drawing too many bees and wasps. I'll have to put it back up again now for them, I loved watching them. I still see them out in the yard, they love all the flowers around here. I have some video of them, if I ever learn how to put my videos on the computer I'll have to make a clip of that.
I thought you might enjoy this link to pictures a lady took of a humming bird sitting on her nest clear up to when the baby birds hatched and few away.
THE BIRTH OF A HUMMINGBIRD
Be sure to click on NEXT PAGE at the bottom of each page; there are 5 pages in all. A lady found a hummingbird nest and got pictures all the way from the egg to leaving the nest. Took 24 days from birth to flight.
The nest is only as long as a toothpick!
