A baby hawk or bird landed on my lawn and it's injured...help?

Well first of all you might want to watch out for that hawk, because if that's not the hawk's baby, the hawk might make that bird lunch. If the bird is a young baby or if it's injured you might want to very carefully place it in a cardboard box with a couple towels and make sure it's safe and warm. Then try and call the 'animal rescuers' and then wait for them to come. If they don't come right away then try and give the bird some water and maybe some bread or whatever it eats. You can research online to try and find out what kind of bird it is. Also wash your hands if you touch the baby bird because those things can have all kinds of germs and bugs! But anyways good luck with the baby bird and I hope that helped :)
