September 4: Northern Giant Petrel nests

The opportunity arose to assist the Tasparks Rangers with the annual Northern Giant Petrel census and nest marking. We set out over two days through snow squalls and wind, to scour the north-west featherbed, looking for every bird on a nest we could see. The Rangers would then carefully approach the nest and check if the bird had a band on its leg, and confirm that it was sitting on an egg. We then GPS logged the location of the nest so that the summer scientists can come through and check on the success rate of incubation, and also band the chicks. We searched  the tussocks and rock stacks, usually finding the  birds nesting up in close to tussock mounds, or rocks. The NGPs Macronectes halli, are a flighty bird, and their drive to not abandon their nest upon the approach of humans was strong, and quite incredible to witness. If the birds flee the nest there is a chance that Skuas will swoop in and eat the eggs. Much stealth was used in sneaking up on the nest, but care also had to be taken not to startle the birds either.
The opportunity to see these huge birds on nests was a wonderful privilege. Their beautiful blue eyes and soft grey plumage will stay etched in my memories.
