The first thing to remember is that if a bird is sitting looking very tame and allowing you to approach – it is almost undoubtedly sick or injured. Healthy wild birds don’t hang around, so bear that in mind.
You also have to remember that any injured bird will be terrified and stressed, and a bird of prey can hurt you if you are not careful. If a bird is not behaving normally, then you can check by approaching it, if it does not fly off, there is probably something wrong, unless it is a baby and unable to yet fly.
If possible wear a pair of gloves to pick up a bird; however the chances of you having a good strong pair to hand are slim. So if you can use a towel or even your coat, walk up slowly and cover the bird from the front with the material, then pick up from the top and try to fold the wings up to the body.
Avoid the feet, hold the legs, but not in a murderous grip – just firmly. If you can find one, put the bird, still in the towel, into a cardboard box, preferably one larger than the bird, but not huge. And make some ventilation holes in the side before putting the bird inside.
