Academic career

Brunton grew up in Henderson, and wanted to be a vet from an early age. [2] She completed her undergraduate degree at the University of Auckland, and for her MSc studied the calls of southern black-backed gulls (Larus dominicanus). [2] In 1981 she embarked on a PhD at the University of Michigan in Ann Arbor, intending to study the behaviour of semi-social wasps – until the departmental colony died. She switched to the killdeer plover (Charadrius vociferus) and graduated in 1987. [2]

Brunton did a two-year postdoctoral fellowship at Yale, occupying the office of the recently-retired Charles Sibley. In 1991 she returned to New Zealand to take up a lectureship as a biostatistician at the University of Auckland. [3] She joined the faculty of Massey University in December 2004, and founded the university's Ecology and Conservation Group. [4] [5] In 2008 she received a Claude McCarthy Fellowship by Massey for her reptile and bird research. [6] In 2018, in recognition of the 14 PhD and 18 Master's students she had supervised since joining Massey she was awarded an Individual University Supervisor Medal by the university. At that time she had published over 120 scientific papers and received two Marsden grants. [7]

Since 2016 Brunton has been head of the Institute of Natural and Mathematical Sciences at Massey, based at the Albany campus in Auckland. [8] [2] Brunton is an advocate for eliminating introduced mammalian predators from New Zealand as part of the Predator-Free 2050 initiative. [9] She was also a vocal opponent of Massey University's proposal to move most science faculty and courses to the Palmerston North campus. [10] [11] [12]

Research

Much of Brunton's research is concerned with the sexual selection and song of southern hemisphere songbirds; in Australasian and tropical songbird species both sexes commonly sing and maintain territories, but in the northern hemisphere, where most behavioural research has been done, usually only males sing. [13] One study examined the mating behaviour of New Zealand bellbirds (Anthornis melanura), and how females distinguished between the friendly and hostile songs of other females. [14] [15] In 2002 Brunton was the first to quantify the song and singing behaviour of bellbirds; she discovered that both male and female birds have distinctive dialects, and that female bellbirds are the sex that disperses to find new territories. [5] Her testing of the "dear enemy" hypothesis with bellbirds – the first time a female songbird had been tested – revealed they were more aggressive to neighbouring females than to strangers, the opposite of what the hypothesis predicted. [16] She also examines the cultural evolution of bird song: how diversity and dialects arise and are maintained, how song memes spread, and the effect of birds dispersing to new habitats. [5]

One of her field sites is the predator-free island sanctuary Tiritiri Matangi, off the coast of Auckland, where with her student Michelle Roper she studied the ecological niche partitioning of bellbirds and hihi (Notiomystis cincta). [2] [17] Another site is Tawharanui Regional Park, north of Auckland, where she discovered by song dialect that the bellbirds which colonised the park had come from Little Barrier Island, not Tiritiri Matangi. [18] In 2013 Brunton received an $820,000 Marsden grant entitled Untangling genes and culture: sex-based song traditions in New Zealand bellbirds, to study male and female dialects; [8] it also supported other projects, including research into the song dialects of grey warblers (Gerygone igata) in Tawharanui. [19] [20]

Her other research interests and collaborations with PhD and MSc students include the welfare of lizard species after conservation translocation, [21] analysing the chemical composition of kākāpō feathers to determine how diet has changed over time, [22] foraging ecology of little penguins (Eudyptula minor), [3] and song dialects in the saddleback (Philesturnus carunculatus).

The South Island takahē is a flightless swamphen indigenous to New Zealand and the largest living member of the rail family. It is often known by the abbreviated name takahē, which it shares with the recently extinct North Island takahē. The two takahē species are also known as notornis.

<span class="mw-page-title-main">Tiritiri Matangi Island</span> Island located in the Hauraki Gulf of New Zealand

Tiritiri Matangi Island is located in the Hauraki Gulf of New Zealand, 3.4 km (2.1 mi) east of the Whangaparaoa Peninsula in the North Island and 30 km (19 mi) north east of Auckland. The 2.2 km2 (1 sq mi) island is an open nature reserve managed by the Supporters of Tiritiri Matangi Incorporated, under the supervision of the Department of Conservation and is noted for its bird life, including takahē, North Island kōkako and kiwi. It attracts between 30,000 and 32,000 visitors a year, the latter figure being the maximum allowed by the Auckland Conservation Management Strategy.

<span class="mw-page-title-main">Kōkako</span> Genus of birds

Kōkako are two species of forest bird in the genus Callaeas which are endemic to New Zealand, the endangered North Island kōkako and the presumed extinct South Island kōkako. They are both slate-grey with wattles and have black masks. They belong to a family containing five species of New Zealand wattlebirds, the other three being two species of tieke (saddleback) and the extinct huia. Previously widespread, kōkako populations throughout New Zealand have been decimated by the predations of mammalian invasive species such as possums, stoats, cats and rats, and their range has contracted significantly. In the past this bird was called the New Zealand crow. It is not closely related to the crow, but looks like one from a distance.

<span class="mw-page-title-main">Tūī</span> Species of bird

The tūī is a boisterous medium-sized bird native to New Zealand. It is blue, green, and bronze coloured with a distinctive white throat tuft (poi). It is an endemic passerine bird of New Zealand, and the only species in the genus Prosthemadera. It is one of the largest species in the diverse Australasian honeyeater family Meliphagidae, and one of two living species of that family found in New Zealand, the other being the New Zealand bellbird. The tūī has a wide distribution in the archipelago, ranging from the subtropical Kermadec Islands to the sub-Antarctic Auckland Islands, as well as the main islands.

<i>Coprosma robusta</i> Species of tree

Coprosma robusta, commonly known as karamū, is a flowering plant in the family Rubiaceae that is endemic to New Zealand. It can survive in many climates, but is most commonly found in coastal areas, lowland forests, or shrublands. Karamū can grow to be around 6 meters tall, and grow leaves up to 12 centimeters long. Karamū is used for a variety of purposes in human culture. The fruit that karamū produces can be eaten, and the shoots of karamū are sometimes used for medical purposes.

<span class="mw-page-title-main">New Zealand bellbird</span> Species of bird

The New Zealand bellbird, also known by its Māori names korimako, makomako, and kōmako, is a passerine bird endemic to New Zealand. It has greenish colouration and is the only living member of the genus Anthornis. The bellbird forms a significant component of the famed New Zealand dawn chorus of bird song that was much noted by early European settlers. The explorer Captain Cook wrote of its song "it seemed to be like small bells most exquisitely tuned". The species is common across much of New Zealand and its offshore islands as well as the Auckland Islands.

<i>Anthornis</i> Genus of birds

Anthornis is a bird genus in the honeyeater family (Meliphagidae). Its members are called bellbirds. According to genetic data, it is a sister genus to Prosthemadera.

<span class="mw-page-title-main">Stitchbird</span> Species of bird

The stitchbird or hihi is a honeyeater-like bird endemic to the North Island and adjacent offshore islands of New Zealand. Its evolutionary relationships have long puzzled ornithologists, but it is now classed as the only member of its own family, the Notiomystidae. It became rare, being extirpated everywhere except Little Barrier Island, but has been reintroduced to two other island sanctuaries and four locations on the North Island mainland. Current population estimations for mature individuals in the wild are 2500 - 3400.

<span class="mw-page-title-main">Red-crowned parakeet</span> Species of bird

The red-crowned parakeet, also known as red-fronted parakeet and by its Māori name of kākāriki, is a small parrot from New Zealand. It is characterised by its bright green plumage and the red pattern on its head. This versatile bird can feed on a variety food items and can be found in many habitat types. It used to be classified as near threatened as invasive predators had pushed it out of its historical range but it is now at least concern. This species used to occupy the entire island, but is now confined to only a few areas on the mainland and some offshore islands.

<span class="mw-page-title-main">New Zealand quail</span> Extinct species of bird

The New Zealand quail, or koreke in Māori, is an extinct quail species endemic to New Zealand. The male and female were similar, except the female was lighter. The first scientist to describe it was Sir Joseph Banks when he visited New Zealand on James Cook's first voyage. Terrestrial and temperate, this species inhabited lowland tussock grassland and open fernlands. The first specimen to be obtained by a European was collected in 1827 by Jean René Constant Quoy and Joseph Paul Gaimard on Dumont D'Urville's voyage. It most likely went extinct due to diseases from introduced game birds.

The whitehead is a small species of passerine bird endemic to New Zealand. It is classified in the family Mohouidae. The male whitehead's upperparts, wings and tail are a pale brown in colour, while the head and underparts are white – in the case of the male an almost pure white in colour. Females and juveniles have similar colouration except that the nape and crown are shaded brown. The black beak and eyes contrast with the white head and the feet are bluish black in colouration.

The pipipi, also known as brown creeper, New Zealand creeper or New Zealand titmouse, is a small passerine bird endemic to the South Island of New Zealand. They are specialist insectivores, gleaning insects from branches and leaves. They have strong legs and toes for hanging upside down while feeding.

<i>Deinacrida heteracantha</i> Species of giant cricket endemic to New Zealand

Deinacrida heteracantha, also known as the Little Barrier giant wētā or wētāpunga, is a wētā in the order Orthoptera and family Anostostomatidae. It is endemic to New Zealand, where it survived only on Little Barrier Island, although it has been translocated to some other predator-free island conservation areas. This very large flightless wētā mainly feeds at night, but is also active during the day, when it can be found above ground in vegetation. It has been classified as vulnerable by the IUCN due to ongoing population declines and restricted distribution.

<i>Amphipsalta zelandica</i> Species of true bug

The chorus cicada, Amphipsalta zelandica, is the most common species of cicada in New Zealand, where it is endemic and found in most areas. They typically live in forests and areas with open bush, where their left-over nymph skins can be seen on tree trunks and branches during the summer months. The males produce their cicada sound in unison, which can reach deafening proportions at the height of their population around February. Groups of cicada can suddenly transition from the typical cicada sound to synchronised clicks, using their wings to clap against the surface they are sitting on.

In ethology, the nasty neighbour effect describes the phenomenon whereby territory-holding animals behave more strongly toward familiar conspecific neighbours than to unfamiliar conspecifics. This phenomenon may be generally advantageous to an animal because the heightened response reduces the likelihood of a nearby intruder entering the territory and taking the resources it contains whereas an unfamiliar or distant territory-holder poses less of a threat. This reduced response minimises the time, energy, and risk of injury incurred during territorial encounters with animals which are less of a threat to the territory holder. The nasty neighbour effect is the converse of the dear enemy effect in which some species are less aggressive toward their neighbours than toward unfamiliar strangers.
