Zookeepers work to acclimate newcomers Natalie and Tuck to their habitat and neighbors.
Nov.29, 2012 Zookeeper Kate Volz keeps an eye on Natalie, a Ruppell's griffon vulture, at the National Zoo. Natalie, who arrived in Washington this past summer with fellow vulture Tuck, did not want to leave her enclosure; Volz uses the broom solely to shift the bird from one enclosure to the next. The zoo sought the vultures because it wanted to diversify its Cheetah Conservation Station and had an available stall. Katherine Frey/The Washington Post Buy Photo
