This week I want to introduce you to a whole family of neighbours. Each one of these feathered friends have their own name; including the Oi, T**i, and Taiko; but collectively you call them Petrels or Procellariiformes. Aotearoa has a lot of petrels and they have played an import part in our biological history. Of the world’s 114 species of petrel, 37 breed here, and 14 of these only breeds here. And it is only when they breed that I get to meet them. I live in the forest, but these feathered friends spend most of their lives on the open ocean, and only come to the forest to breed. But when they do they transfer a lot of nutrients (in their poo) from the ocean to the forest. Before you humans arrived, millions of petrels nested in our forests, and helped the forest to grow strong and healthy.
Now their numbers are a lot smaller, as overfishing impacts their ocean food, deforestation takes away the safe places for them to breed, and introduced predators kill them when they are most defenceless. Some of our human friends, including A Rocha Aotearoa and the Karioi Project (https://arocha.org.nz/karioi-project), are working hard to ensure they have safe places to breed. If you want to learn more about Petrels and the work of the Karioi Project watch the video on their website.
However, even when young petrel fledglings leave the nest, they are still not safe. One of the recent threats to petrels has been light pollution. As cities like Auckland use more and more LED lights, such as those that light up the Harbour Bridge and Sky Tower, more and more petrels are becoming confused and injured when they crash into mad made structures. Thankfully some more human friends are doing their best to come to the rescue of these feathered friends. The wonderful people of BirdCare Aotearoa (https://birdcareaotearoa.org.nz) are rescuing these injured birds and nursing some of them back to life. It is hard work and not all of them make it, but you can support them financially by donating at their give a little page: https://givealittle.co.nz/cause/lost-from-sea-light-impacted-seabirds
Another way you can be a good neighbour for these feathered friends is by reducing light pollution. In your own homes you can make sure garden lights are directing light towards the ground, planting lots of trees and other plants to defuse light pollution, and just turning more lights off in autumn when petrels are fledging. You could also do your part to influence others by writing to organisations like Vector, Sky City, and Waka Kotahi and asking them to turn down their Auckland light displays in autumn.
A special thank you to BirdCare Aotearoa for you love of our native birds and the presentation you gave to North Shore Forest and Bird recently, which included the slide in this post.
