It depends on where you live as to how feeding wildlife is viewed. Here where I live it is discouraged by the state and departments like the game and fish. In the area where my daughter lives a couple of winters ago there was a couple that were feeding the mule deer. Sadly, they lived near a busy road and were encouraging the deer to cross the road from the river bottom to where they were feeding them and several of them were hit and killed by vehicles before the game and fish department came and took the feeders and used cracker shells to discourage the deer from being near the road. As with all of the other things that we do a little thought goes a long way so that the end results are good the way we intend them to be. In one of the parks near the river there are people that feed the ducks and Canada geese everything goes well unless they get too much white bread with larger amounts of salt feeding them grain is what the city and state recommend. They did get the avian flu and all but three of them died from it this year. there again it depends on the location they aren't near a busy road and in a park on the edge of the river. They do however lose their fear of humans and get aggressive toward people wanting to be fed by everyone. Every year there are close to 80 people killed by deer in the United States, bucks in rut and does with fawns are the main culprits, once again a little thought and knowledge goes a long way in the outcome and how the behaviors of the wildlife affect us. The situation dictates when it's a good or when it's not such a good idea. In my neighborhood there are a lot of cat people that allow their cats to roam so if you were to feed the birds, as a lot of people do, you will be getting a bunch of birds killed by the cats as I see the cats hunting the birds in peoples hedges and wind rows where the birds gather out of the weather.
