I think I agree with the above mentioned except ...that I do try and protect any fallen baby birds from neighborhood cats and dogs.. Watching the whole process is really amazing.. We had a cardinal family in the bushes next to our house last year and of the little ones tried its wings and lost power so to speak he ended up at the bottom of a lilac bush.. I did lift him(or her) on to a higher branch.. for safety.. The mother and father continued to care for the little one and by the end of the day he( or she) had flown safely back to the nest...KGH
