The weekend crew gets to choose!

Hey, I haven't been assigned a topic for the Urban Nature Abecedarium for the letter "H" yet, so it falls upon you guys. I'll tally the responses sometime tomorrow, I guess. So far two people have suggested four topics: Hawks, Hornets, Homing Pigeons and Hanta Virus. Someone also suggested Humans, but I wrote about those guys recently here.

I'm putting in an early vote for Ichneumon for the next time, but let's first concentrate on "H."
