Can we bring a fledgling in? Its quite cold out and the little guy isnt moving just sitting there mouth open head back and squeaking

They probably aren't open now. Put the bird in a box with a towel and lid and let him quietly rest until morning. No peaking to any little children as it can upset the bird and he's already stressed. Call them or go in when they open with the bird. PLEASE go out and get the bird. Sounds like he's hungry but it's advisable not to feed him.

Yes please!

I'm so sorry i don't no much about birds so i would ask wildlife Calif pres.

Yes they will take it
