Tucson Electric Power employees work to install power poles for two new enclosures for golden eagles and other injured birds of prey at the Tucson Wildlife Center on the city's east side. TEP has been partnering with the center since the 1990s.

Golden eagles can have a wingspan of more than 7 feet, which makes it difficult for them to exercise in the current enclosure.
