It's that time of year when veterinary hospitals get an increased number of calls about wildlife, in particular newborn or young animals that kind, well-meaning citizens think have been abandoned.
In most cases, the truth is that the adult has left the babies safely hidden to go in search of food and will return soon, or is hiding nearby waiting for the humans to leave. Removing the babies often actually lowers their chances of survival, since veterinary hospitals and humane societies are often just not equipped to provide the around-the-clock specialized care that a wild newborn requires. Wild babies that are handled by humans will likely not survive if returned to the nest, so the best course of action is really to assume to that the mother is nearby and coming back.
It's difficult to remember that wildlife is just that - wild. They are well adapted to their surroundings, and WE are encroaching on THEIR space. We encourage you to leave the nests and litters that you find this spring, and trust that nature will look after them.
Truly injured wildlife or abandoned litters can be taken to a wildlife rehabilitation centre, of which there are several in the area, however we recommend that you call them first before touching the birds or animals. They will be able to direct you in the best course of action and let you know if they have space or resources available.
