Hummingbird Saga

This morning (June 2nd) as I pulled out of the driveway and started down the street, I noticed bird crap on the front window. I turned on the windshield wipers and spray to wash the window. It sort of came clean but then I noticed a pine cone(?) strange leaf (?) stuck to one of the windshield wipers. I turned them on again and the thing didn't budge...it was still stuck there. I was weirded out by this little brown gray shape that didn't really look like any pine cone or leaf we'd have around here. So I stopped the car at the corner and got out to inspect. To my horror it was a baby hummingbird attached to the wiper. I felt it had to be dead especially after what I just put it through. I inspected it and it seemed somewhat alive although it looked to be in shock, it was wet from the windshield wiper fluid and even though it had some feathers, it was clear, it had a ways to go. It had to have fallen out of a nest that was in the tree my car was parked under. I got a kleenex and wrapped it around the little fella... (he had iridescent green feathers just showing on his back) and tried to pull him off the windshield wiper. He was holding on for dear life. I put him on my lap and drove back to the house. I inspected the tree and fortunately found the nest within reach. There was a bird already there and I wondered if this little guy had been shoved out of the nest. I figured I had to give him one more chance and tried to deposit him on top of the nest. After several unsuccessful attempts, that resulted in him falling to the ground because the occupant brother didn't want to give up his spot, I got the little guy to grab hold...and there I left him, perched on top of his brother in the nest.
After several hours out I returned home and took a look. Both little guys were nestled in the nest now and I took a picture. If that little guy survives, he'll have stories to tell.
After returning that day, I checked on the little hummers and found the 2 little guys nestled side by side in the nest. I checked maybe one or two more times the next couple of days and saw near the end of day, the mother and 2 Jr. hummers in the nest. Then about June 5th, the weather turned colder and the wind was blowing. I went out just about sunset and peered at the nest. Nestled in that nest were 4 hummingbirds. I figured it had to be mom, dad and the 2 little ones. The nest stretches to accommodate as it is made from tiny vegetable matter, black- widow spider webs that give it strength and their great stretchable quality and then down presumably from the hummingbird's plumage. A few days later, the nest, all stretched out, was an empty abode. The family had taken flight.
