Bats in Downtown Seattle?!

There are bats downtown Seattle?! Well, I suspect at least near the corner of 4th and Pine st.

While walking home from the flick 'Departed' (which is a mighty good show might I add), my friends and I noticed hundreds if not thousands of chirping nocturnal creatures fluttering about in the trees on 4th across from Macy's. On ground near the inhabited trees, I found what looked like drops of bat poo aka guano. Hmmm... I wonder if Batman is lurking around the corner somewhere.

I Live'd it and found, yes indeed there are bats to be found downtown and up in Greenlake. Unfortunately, with Google I had a tougher time in coming up with relative hits.
