There is a nice heron that hangs out on campus. Sometimes I see it hunting around the guesthouse. Last week I finally got a few decent pictures of it.
I am almost certain it is a Black-headed Heron (Andea melanocephala). According to my bird guide, black-headed herons like to hang out in grasslands and drier areas in addition to wetlands. The heron I see prowls around in dry drainage ditches. I assume it is looking for insects.
