If you find an injured wild animal please call the vets and also the RSPCA on 0300 1234 999 (or look at their website). The RSPCA will give you a reference number to help cover the costs of first aid.
Please exercise extreme caution when approaching or handling injured animals, whether wild animals or pets, as they may behave unpredictably or aggressively.
Also, be very careful if handling ill or injured bats. A very small proportion of bats in the UK (most of which have been Daubenton's bats) carry lyssaviruses which are rabies viruses. In 2002 a man working with bats in Scotland died after being bitten by an infected bat. In 2006 a bat sick bat found in Abingdon, that later died, was found to be infected with lyssavirus. Most infected bats do not show signs of the disease. If you must handle a bat, wear thick gloves. If you require further advice, please call the Bat Conservation Trust's Bat Helpline (0845 1300 228). The Bat Conservation Trust's website provides more information here.
If you find a young bird on the ground, unless it is obviously badly injured, please DO NOT pick it up. It is most likely being cared for by its parents. Yes, it might be at risk from local cats or other wildlife - that is the way the world is, but on average such birds are likely to be far worse off if you interfere.
We do not normally charge for the initial treatment of injured wildlife.
