Beak Full of Sticks

A Cape Griffon vulture (Gyps coprotheres) with a beak full of nesting material at the Albuquerque BioPark (Rio Grande Zoo) in New Mexico.

Observed a few days later (there is sound, but you may need to turn your volume up to hear it): [link]
As this is one of the many vulture species threatened with extinction, I am hopeful they are letting these vultures breed. I am also hopeful that if they are breeding, I can see the young ones.
