I do not condone just jumping in to wrestle a raccoon from something it is trapped in or to pull a yogurt cup off of a skunks head-- both animals are rabies vectors and doing good can come at a cost to you. When a situation is dangerous, I advise calling your local shelter, your parks department, or your local veterinarian as they often have contacts for people who can help, safely. But one way you can assist (in a very big way) is to keep eyes on that animal (from a safe place) and your phone handy so that you can help people locate that animal.
One animal rescue that is easy to assist and help are when little songbirds strike windows. And that is what happened today.
In NYC, the local Audubon keeps a database (d-bird) of bird strikes so not only can you possibly assist a bird, but also help gather data to know where certain areas are dangerous to birds in terms of buildings and other glass/reflective structures.
|In a box he went, placing a stunned bird into a box- and closing it up provides a dark, quiet place for them to calm and recuperate, at first this bird just laid as it was placed.|
