I remember rescuing some sparrows along with the duck, deer, and turtles.

We used to have this stupid metal birdfeeder, with a tray, which had little slits cut in the tray. The sparrows kept on getting their legs caught in the slits and I would look out the window to see a sparrow hanging upside down franticly trying to get loose.
So my dad and I got it's leg out. I held the bird in my hand to keep the weight off its legs, and my dad took a pair of plyers and opened up the gap. He checked over the leg and it was intact, but it flew away before we could take it anywhere to get it looked at.

I felt really good that day, I was only around 10 or so- but I wished we could have gotten him looked at to make sure it was 100% ok....
