Injured adult Tree squirrels (or ground squirrels)should be handled carefully as they can give you a nasty bite, especially when in severe pain.
Use a thick towel to wrap around the squirrel and have the transport container next to you so you don't drop an injured animal that is trying to get away. They may chew their way out of cardboard boxes so a plastic
container is better. We have seen quite a few squirrels suffering from west Nile virus (that
have recovered)so neurological symptoms may not be from an injury. If an adult female is found, make sure you go back and check the area for youngsters that may be calling for their mother. Baby tree squirrels can make a very high pitched squeaking noise when in distress so listen carefully.
A Nest that has blown down can be reconstructed by placing it, along with uninjured babies, into a box or
laundry basket, just slightly bigger than the nest. You can add a little material if there is not much to work with. As long as you give her a chance, the mother will reclaim her young and continue to raise
them, either in the reconstructed nest or by moving them to an alternate site. Remember to put it in an area not in view of predatory birds.
Babies that have fallen from a tree should be checked for injuries. Look for blood coming out of the nose, lacerations ,or, any obvious broken
bones by placing them on a towel inside a large box to see if they move around normally. Watch for any tremors
and look for parasite infestation such as mites or fly eggs. (clusters of beige coloured rice shapes embedded in the fur) . If everything checks out OK and the baby is warm to the touch, you can try to reunite it with its mother by placing it on, in or at the base of the tree. The safest way is to put the baby into a container as high as you can. This should be something that the mother can get to easily but not something that the baby will crawl out of and fall. If the squirrel is injured or parasites are present, call a rehabilitator for help.
