The college campus where I work is not the best environment to watch birds, but it's certainly not the worst. There is a sheep pasture with a heavily vegetated drainage pond, some open fields grazed by cows and horses, and lots and lots of diverse species of mature trees, both native and non-native. Overall the number of species I've seen there is about half what I've seen along the Tuolumne River Parkway Trail where I do most of my searches.
But there are still some neat species to be seen. One of the pretty little birds I occasionally run across on campus are Say's Phoebes (Sayornis saya). Say's Phoebes are members of the flycatcher family, and their behavior fits their name. They'll perch on a branch, sally forth when they see a bug, and return to their perch. I saw this one while walking between classes yesterday.
