Detailed description of bird: Observed two individuals. Both very similar to a Turkey Vulture in overall appearance and flight pattern (dihedral wings, tippy flight). Overall dark brownish black with silvery wing linings and fine barring on the secondaries and primaries noticeable when seen well from below. Wing tips splayed. Tail (viewed from below only)with alternating dark and light bands (thin light band on the tip, wider dark band, light band, and dark undertail coverts). Yellowish cere and legs. Legs much shorter than the tail when observed in flight from below. Both birds were molting primaries which aided in picking them out from the large flocks of Turkey Vultures in the area. (see photos)

Additional comments: This is the first time I've seen two Zone-tailed Hawks occupying an area regularly throughout the summer. Although I did not see any young birds, or direct evidence, I believe its possible they were nesting in the cliffs along the Kolob Creek Canyon north of Lava Point.
