Mention ocean-going birds and the mighty long-winged albatross comes to mind. But the ball of fluff I hold in my hands is no heavier than a pompom and not much larger.

| White-faced storm petrel chick |
It's February 2021, I'm volunteering for a week on Te Mana o Kupe (Mana Island), assisting with the translocation of white-faced storm petrels, takahikare moana - also known as Jesus Christ birds because the adults really do look like they're walking on the waves.

My job is 'runner', although I'm careful not to actually run. These birds are too precious for me to risk tripping on a tree root and dropping the specially adapted carry-box. We runners collect chicks from their burrows in number order and deliver them to the feeding caravan. A general health check follows, they'll be weighed, have their wings measured and then crop fed a teaspoon-sized serving of sardine smoothie. Then we carefully return them. Our handling training has taught us how to protect their long dangling legs and at the same time prevent them from springing out of the box, our hands or their burrows.
It's anxious work. My movements are careful, deliberate, each step thought out. I kneel at each burrow, prepare the box, work out my strategy before I lift the lid. Even then I lift it only enough to see where the bird is, where its head is, just in case I need to reassess my strategy. The only time I relax is when the bird is back in the burrow.

It's a relief to sometimes take a turn in the caravan as 'recorder', writing down weights, wing-lengths, feed quantities and other data. It's an opportunity to see the big picture, how many birds have fledged, how many are ready to have have their tunnels unblocked so they can venture out, which birds might need a second feed.
As I do my rounds I'm in awe of the amount of volunteer energy and dedication required to get this project underway. Each of the hundred burrows has been hand dug, the box and tunnel within have been built to specifications. Sandbags (weight for lids and burrow insulation) have been filled by hand. Removable barriers to block the tunnels have been created out of number 8 wire, mesh, needle and thread.

All this effort isn't to rescue a species. Takahikare moana aren't a rare seabird, over one and a half million live on Rangatira in the Chatham Islands where these chicks were translocated from. It's to rescue an island. Mana Island needs the guano-rich diggings of seabird colonies to help restore its ecosystems.
 |
| Evidence of a rich eco-system. Even in an artificial burrow - guano, leaf litter, geckos, insects, spiders and other invertebrates abound |
Because most adult seabirds return to the nest in the colony they fledged from, the strategy of translocating chicks can be a successful way of establishing a new colony. Sooty shearwaters, tītī; fluttering shearwaters, pakahā; fairy prions, tītī wainui; diving petrel, puaka are all established or becoming established on the island.

I took part as a volunteer for Friends of Mana Island.
There's an overview of this and other white-faced storm petrel translocations on the Friends of Mana Island Website https://manaisland.org.nz/white-faced-storm-petrel-translocation-project-2019-2021/
Radio New Zealand, Producer Alison Ballance put together a fascinating overview of the whole process, Alison put this programme together while also volunteering on the project during the same week https://www.rnz.co.nz/national/programmes/ourchangingworld/audio/2018786615/more-seabirds-for-mana-island
