Today I crossed one thing off my bucket list. Seeing a kākāriki karaka nest fledge! I had never seen a nestling take its first flight and make the change from nest-bound infant to flying bird. Today I did. No photos, I went for video instead. I knew the nest was due to fledge from the appearance of the nestlings, and that some of the birds may already have left.
No tripod, so I was leaning against a tree holding the camera as still as I could. The male arrived and landed in the foliage of an adjacent tree about 8-10m or so from his nest where he remained for the duration. He called briefly to his nestling. The nestling spent about a minute making up its mind then flew to dad. Here's a record of the whole event, minus the first few seconds where dad is calling. In the first few seconds of the video the male can be heard calling from the left. The other parakeet sounds are the nestling.
By the way, the string going past the nest had a purpose. During the Brook's first kākāriki karaka breeding season the Department of Conservation inspected a few of the first nests. When a nest is considered accessible, they fire a bolt from a crossbow attached to string. After multiple attempts (this may take hours) and the string eventually ends up going up, and through, and down where it's wanted, the string is used to pull through a rope. A DOC employee then ascends the rope using jumars and inspects the nest with an inspection camera. Examination of this hole (February 2022) provided the first evidence of hatchlings with their mother.
Once a nest site has been 'shot', the string is left for possible use at another stage. E.g., the time may come when the Brook will provide a source of eggs to maintain genetic diversity in kākāriki karaka populations elsewhere.
