My son found two little tufted titmouse birds outside today. Luckily I was able to get them before the dogs did! They are small, but not babies. In fact they are mostly feathered, but it appears they got tangled up in each other. After prying one's feet from the other's wings, I realized they look like they might have sap all over them. One of them is missing all but two feathers from one wing. What is the best way to get the sap off? I feel like one could definitely fly away if he was clean and dry. The other needs to regrow some feathers.
