An injured or sick mourning dove has taken up residence in my herb garden just outside my back door in Hanover.  I've provided water and a bit of food (sunflower seeds, cracked corn, millet, small amounts of fruit) but I fear it will die if left on its own. It appears to have a balance problem, though it can fly short distances and is eating and drinking.   Are there local organizations that might take it in for rehab?  Any suggestions are welcome.  Thank you!
