If you are thinking of place a geocache that pertains to Hedwig the Owl (Harry Potter's Snowy Owl) what better place to put one in Rice University. Within Rice, the owl is considered the University's mascot throughout a variety of sports. At this location within Rice University, there lay a bronze owl of a barn owl after the school's mascot. Nearby the statue there is the Brochstein Pavillion, a great place to have a small meal, drink or chat and the lawns of Rice University.
Hedwig was purchased by Hagrid (the groundskeeper at Hogwarts, the School of Witchcraft and Wizardry in the UK) in Diagon Alley as a present for Harry Potter's 11th Birthday on his first trip to Diagon Alley. Harry continued to use Hedwig for all of his years at Hogwarts. Hedwig was a highly intelligent owl who would show affection to Harry by nibbling his ears or fingers.
