Denver Zoo is celebrating its first-ever successful hatching of a kea (KEE-yah), a large, vulnerable species of parrot. The female chick, named Scarlet, hatched on February 8, 2017, and has been hand-reared by zookeepers since then at the Zoo’s Avian Propagation Center. Scarlet’s arrival is special as she increases the North American zoo population to only 38 keas, 14 of which are female. Zookeepers have taken extra steps to assure her continued well-being. She is still growing behind the scenes, but will make her public debut soon at the Zoo’s Bird World habitat.

This ‘Kea-crow suite movie’ shows both species, kea (Nestor notabilis) and New Caledonian crows (Corvus moneduloides), employing all four different solutions of the Multi Access Box apparatus: string, ball, stick and window. The video illustrates the techniques used to employ the fourth and final solution of the two animals, the kea Kermit and the crow Uek, that mastered all tasks: the crow Uek uses a tool to poke the reward off its platform after opening the window solution and the kea Kermit uses a complex multi step technique to insert the stick tool into the appropriate opening (as described in detail in the results section).
