Activity #1 - I was drawn to the American White Pelican on the Wall of Birds because of its sheer size. I recently took a trip to the Dakotas and was surprised to see a Pelican on display in one of the National Park visitor centers and was able to learn that the Pelicans breed inland and pass through the Dakotas.
Activity #2 - On my outdoor walk through a natural forest/creek area, we saw a large collection of vultures on the ground. We were not close enough to see if there was a carcass there, but I imagine that there was. Vultures would fit into the Raptor group. On our trip to the Dakotas, we saw a Western Meadowlark which I believe fits into the Songbird category. Another bird we saw in the Dakotas was (I think) a pied-billed grebe - which would be a swimming bird/water fowl.
