Small, but still a giant? Fossil of new species of giant petrel found in New Zealand

New Zealand fossil-hunter Alistair Johnson has added a new species of giant petrel to the list of those he has discovered along the South Taranaki coast over the past 15 years. 

Named in honour of his late partner, Tina King, Macronectes tinae was found by Johnson in sediments from a geologic formation known as the Tangahoe Formation. The wide band of layered sedimentary rock dates from the Pliocene and was, when it formed, below sea level some 3.4 to 3.0 million years ago. Exposed cliff faces at its western end have proved a rich source of marine fossils.

The near complete skull and the fragmentary left humerus of the newly described giant petrel is the first reported Macronectes fossil.

Giant petrels are the largest birds in the family Procellariidae and are represented by two present-day species, both listed as of globally Least Concern; the Southern Macronectes giganteus; and the Norther M. halli.  Alhough morphologically similar, Macronectes tinae was a smaller bird than its living relatives.

“The skull is diagnosed by its overall smaller size, a proportionately longer apertura nasi ossea, and potentially by a shorter os supraocciptale. The humerus is diagnosed from both species by a proportionately less deep shaft, a more prominent medial portion of the epicondylus ventralis, and a larger and fusiform fossa medialis brachialis.”

Johnson also has a fossil named after him in a small albatross he found in 2011, Aldiomedes angustirostris .“Al” in relation to his name and “diomedes” after the Greek mythological figure from whence the albatross family was named.

The fossil has been added to the collection of the Te Papa and Canterbury Museum in Wellington and Johnson, as has been the case for his previous finds, has been gifted a replica in its place.

First time for everything: Westland Petrel discovered on a remote beach in Western Australia

Westland Petrels are familiar with Australian coastlines, just generally not the 20 788-km stretch that is Western Australia’s.  

A member of the public recently found a Westland Petrel at Wylie Bay near Esperance, a town located on the southern coast of Western Australia. The visibly unwell bird was taken to a wildlife carer, who, not recognising the species, contacted a seabird expert who identified it as a Westland Petrel.

Endemic to New Zealand, the globally Endangered Westland Petrel Procellaria westlandica is a colonial, burrow-nesting, annually breeding species. The Westland Petrel's non-breeding range extends east from New Zealand to Chile, though sightings have been known off south-eastern Australia.

When found, the petrel weighed just 580 grams, less than half of what it should be. The wildlife carer was initially able to keep the severely underweight petrel alive, however it was discovered dead on the morning of its fourth day in care.

The bird is now in possession of the Western Australia Museum (WAM), where a taxidermist prepared the specimen for the museum’s collection; the body of the bird was skinned and preserved as a dry specimen, whilst tissue samples from muscle and liver were taken to be kept in frozen storage. 

ACAP contacted WAM’s Acting Curator of Ornithology, Dr Kenny Travouillon to ask if any further information on the specimen had come to light since the specimen had been prepared for the collection. He advised the petrel was a subadult male, and the stomach content was full of sardines, its last meal given by the carer (no plastics).

The Museum has a keen interest in documenting and preserving vagrant birds as increases in their sightings may prompt research into factors behind an escalation such as climate change.

Further details on the discovery of the Westland Petrel in Western Australia can be found in coverage given by the ABC (Australia’s national broadcaster), here.

ACAP’s fourth collaboration (Project #43) with Artists and Biologists Unite for Nature (ABUN) for World Albatross Day on 19 June and its 2023 theme of ‘Plastic Pollution’, set to last for three months from the beginning of the year, is now well over halfway through, so a progress report is due  The response to this year's theme has been excellent to date, with 22 artists contributing a total of 55 artworks (view them all in an ACAP Facebook album).  Several have produced more than one, with honours currently going to Snah Kritzler, who has submitted no less than 16 evocative ballpoint pen drawings, several of which have been featured by ACAP Latest News (click here).

“I have always been a hesitant artist.  Originally, I only painted interiors and furniture as a professional  interior designer.  But I became passionate about watercolour painting after acquiring my first professional grade watercolour set in 2015.  Back then, I had been an edible organic gardener and only wanted to paint my vegetable harvests from the garden to illustrate and publish books, so children can get attuned to growing food from seeds.  I have become even more passionate about watercolour painting using water gathered from the rain, snow, lakes, rivers and waterfalls every place I go”.

“I guess growing and painting vegetables was just a creative gateway.  I then started seeking a higher purpose and happily began painting wildlife, including birds for ABUN projects from 2019.  In 2022, I had COVID, which I found a scary experience.  Yet, this became my breakthrough not to be hesitant anymore in my creative expressions.  The real awareness that we are all going to die made me choose to become even more straightforward and direct in my life purpose to make a change through painting and book publishing until my final day comes”.
