Kakapo are inactive and slow moving during the day. At night they are an entirely different creature. They can run through brush with incredible speed. When Sirocco heard us at the top of the hill, he raced to meet us. Although Sirocco does many things that are very parrot like, kakapo are at the same time so different from any other parrot I have encountered. I studied his body language as he approached us, trying to determine if he was interested, sexual or was it something else. There were three of us there trying to understand what this bird was communicating. When he tried to bite my boots it finally became clear. We definitely witnessed our first full on display of aggressive behavior. In addition to getting a better handle on body language associated with aggressive behavior we also needed to determine the triggers. We came up with a long list of things we thought caused Sirocco to aggress. (Movement, darkness, squatting down, location, and later I learned that male kakapo will also defend their bowls/territory.) In the end we decided the best thing to do is to have one person prepare his feeding station while he is being trained in the display away from the area where he aggresssed. Then when it is time for him to go explore we wouldn't be near his bowl to trigger aggressive behavior.
However we knew there might be other situations in which avoiding him might not be possible. After Zealandia he was going to return to Maud Island. He would have free range of the island and would likely be coming to visit the rangers at their houses. This meant there could be a situation in which Sirocco might show aggressive behavior. Knowing this we decided it would be worthwhile to train him to do a behavior that is incompatible with attacking. We decided upon stationing. In the display on Zealandia we had already been training this behavior. A series of logs and stumps made for great training stands and stations for our evening sessions. Our plan was to make several stations near the houses on Maud. If Sirocco had enough history for being reinforced on a station he may very likely choose to go there to get reinforced rather than aggress. Also rangers could redirect Sirocco to his station prior to any undesired behavior being exhibited.
To reduce the likelihood Sirocco would show aggressive behavior near his feeding station we started training him in the daytime. As I like to say he was a “rock star.” He immediately grasped the concept and proved once again how eager and ready he was to learn. As you can see in the clip we gradually added criteria to his stationing. For example we increased the amount of time between delivery of reinforcers. We added some of his known triggers such as movement, squatting down and turning our back to him. By training in the daytime we took away one of the factors that seemed to contribute to aggressive behavior. This allowed us to have successful interactions that we could reinforce. Overtime we could gradually add training this behavior closer to sunset and finally in darkness. As you can see from the video, Sirocco was all about it and ranger Linda did a great job training him.
