Neinei Tree, Leaves and flower – Cook Islands, Rarotonga – Gerald McCormack

The Neinei tree of Rarotonga has such a spectacular flower that the tree itself is often called the Pua Neinei (Flower-of-the-Neinei). The Neinei (Rarotonga Fitchia) is a small tree common in the mountains, from the base of low valleys to the top of the highest mountains. It is not found anywhere else in the world, although it has a few shrubby relatives in French Polynesia.

The large leaves are in terminal bunches, and they often have conspicuous grooves, cut inward from the edge. These are the feeding grooves of the 15mm Neinei Weevil (Rhyncogonus lineatus), which feeds exclusively on the young leaves of the Neinei. Like the plant, this weevil is not found anywhere else in the world, although it does have close relatives in Hawaii as well as in French Polynesia.

The Neinei flowers from April to June. The flowers are large, spiky, bright orange and full of nectar.

One animal which seeks the nectar as food is the `Ī´oi (Rarotonga Starling). The flower of the Neinei is bent back towards the branch, probably to make it easier for the starling to get to the nectar. Because, while the starling searches for the nectar, it pollinates the flower, thereby enabling the plant to develop seeds. The dark grey `Ī´oi, which has a bright yellow eye, is the most melodious native bird on Rarotonga. It’s typical call of “ee-oi, ee-oi, ee-oi”, is reflected in its Māori name.

The Rarotonga Starling is not found anywhere else in the world, and its closest relative, the Mauke Starling (Aplonis mavornata) of Maºuke, which was last recorded about 150 years ago, in 1825. In the olden days the `Ī´oi was the protector of fugitives and food-gatherers in the forest, because it called when other people approached. A famous traditional saying was: `Ī´oi -karanga (starling warns).

The fame of the starling’s warning call was reflected in the first anti-government newspaper, the Ioi Karanga, published during 1898.

Moss launched the bilingual Te Torea in 1894, it was published by Henry Nicholas, a European-NZ Maori in Rarotonga since the 1860s, on the leased Government printing press. The first Catholics and SDAs settled on Rarotonga in 1894. The SDAs included the American SDA Dr Caldwell, who became the first resident doctor in 1894 and a makeshift hospital was opened in May 1896. In October he was told to stop having religious meeting in the hospital. The Craig brothers arrived in March 1897 and Dr George Craig was within weeks made hospital superintendent. Craig and a number of Europeans started to strongly oppose Moss’s administration. In January 1898 Makea Ariki, exploiting anti-Moss situation, had the printing press forcibly taken from Nicholas as part of her own campaign against Moss. She then started to print the Ioi Karanga on the press. A short-lived newspaper. In mid-1898 Moss, in ill-health and 71 years old, resigned. He left in September.  Gudgeon immediately appointed George Craig as medical officer.

Cook Islands Fruit-Dove (Kūkupa)

Adult and chick – Joseph Brider, 2021

Gerald McCormack, CINHT

The Cook Islands Fruit-Dove (Kūkupa, Ptilinopus rarotongensis) lives only on the islands of Rarotonga and Ātiu, making it a 2-island endemic of the Cook Islands. It was recorded on Ma‘uke in the 1820s but was lost sometime before 1970 – cause unknown. It was also in the fossil record of Mangaia but was lost before the arrival of the Missionaries.

Life in the Karekare Bee Hotel

Life in the Karekare Bee Hotel

Karekare Bee Hotel at 6pm on 28th December 2021 with suites numbered left to right

We built a small hotel to study the behaviour of the local Leaf-cutter Bee, which usually nests around March or April. The hotel had three 12mm holes about 50mm long drilled to overlap two blocks of wood so that separating them would open the holes for inspection. As a hotel, each hole is a suite and any occupying bee or wasp makes its own rooms by building partitions or doors. Within a suite, Room 1 is the first to be partitioned and will contain the oldest offspring.

Early morning on the 28th December 2021 it was unexpectedly noticed that a large Tahitian Mason Wasp had already sealed Suite 2 with mud and was starting work on Suite 3, which she sealed in the early evening.  Suite 1 remained vacant. Twelve days later, on the 9th January the hotel was opened for inspection. Continue reading →
