I'm always happy to see pigeons around. They are a lot rarer these days. I remember, before West Nile came around, they would blanket an area. People would have to wash their cars every other day because they would poop on the roofs. Especially if you parked under a tree.
It was the same with crows and sparrows too. Now, you're a lot less likely to see cool birds in urban areas.
Around the mich med main campus/huron river, in the winter, there will be a couple of days here and there that thousands and thousands of crows decide to blanket the campus with poop and caw at you as you try to navigate it with your feet. Good idea to have a hood up or hat on.
