'Tax', a Great Horned Owl from the Spring River Zoo, was a special guest Tuesday, April 8, 2008, at the Yucca Center in Roswell, New Mexico during Goddard Days, a science discovery exposition held for area school children presented by the Roswell Recreation Department and the Roswell Association for Gifted Students. The owl was born April 15, 2006, at the zoo thus earning the name Tax.
