Fidelity to nest site and mate in Fiordland Crested Penguins Eudyptes pachyrhynchus. Marine Ornithology 27: 37–41. Fiordland Crested Penguins Eudyptes pachyrhynchus are the least gregarious of the crested penguins, breed- ing in caves, burrows, and under dense vegetation along the coast of Fiordland, New Zealand. A popula- tion on Open Bay Island was monitored, with varying degrees of intensity, from 1988 to 1995. During this period, 175 adults were banded in three semi-contiguous areas and their returns to 46 mapped nest sites were recorded. In 1989, reproductive success to the crèche stage was also known. Return rates (used here as minimum annual survival estimates) ranged from 53–83% with means of 71% for both sexes. Mean nest fidelity averaged 76% for males and 72% for females with slightly lower values for mate fidelity (64% for males, 62% for females).

  • New Zealand Comprehensive II Trip Report 31St October to 16Th November 2016 (17 Days)
    New Zealand Comprehensive II Trip Report 31st October to 16th November 2016 (17 days) The Critically Endangered South Island Takahe by Erik Forsyth Trip report compiled by Tour Leader: Erik Forsyth RBL New Zealand – Comprehensive II Trip Report 2016 2 Tour Summary New Zealand is a must for the serious seabird enthusiast. Not only will you see a variety of albatross, petrels and shearwaters, there are multiple- chances of getting out on the high seas and finding something unusual. Seabirds dominate this tour and views of most birds are alongside the boat. There are also several land birds which are unique to these islands: kiwis - terrestrial nocturnal inhabitants, the huge swamp hen-like Takahe - prehistoric in its looks and movements, and wattlebirds, the saddlebacks and Kokako - poor flyers with short wings Salvin’s Albatross by Erik Forsyth which bound along the branches and on the ground. On this tour we had so many highlights, including close encounters with North Island, South Island and Little Spotted Kiwi, Wandering, Northern and Southern Royal, Black-browed, Shy, Salvin’s and Chatham Albatrosses, Mottled and Black Petrels, Buller’s and Hutton’s Shearwater and South Island Takahe, North Island Kokako, the tiny Rifleman and the very cute New Zealand (South Island wren) Rockwren. With a few members of the group already at the hotel (the afternoon before the tour started), we jumped into our van and drove to the nearby Puketutu Island. Here we had a good introduction to New Zealand birding. Arriving at a bay, the canals were teeming with Black Swans, Australasian Shovelers, Mallard and several White-faced Herons.

  • Nine-Banded Armadillo (Dasypus Novemcinctus) Michael T
    Nine-banded Armadillo (Dasypus novemcinctus) Michael T. Mengak Armadillos are present throughout much of Georgia and are considered an urban pest by many people. Armadillos are common in central and southern Georgia and can easily be found in most of Georgia’s 159 counties. They may be absent from the mountain counties but are found northward along the Interstate 75 corridor. They have poorly developed teeth and limited mobility. In fact, armadillos have small, peg-like teeth that are useful for grinding their food but of little value for capturing prey. No other mammal in Georgia has bony skin plates or a “shell”, which makes the armadillo easy to identify. Just like a turtle, the shell is called a carapace. Only one species of armadillo is found in Georgia and the southeastern U.S. However, 20 recognized species are found throughout Central and South America. These include the giant armadillo, which can weigh up to 130 pounds, and the pink fairy armadillo, which weighs less than 4 ounces. Taxonomy Order Cingulata – Armadillos Family Dasypodidae – Armadillo Nine-banded Armadillo – Dasypus novemcinctus The genus name Dasypus is thought to be derived from a Greek word for hare or rabbit. The armadillo is so named because the Aztec word for armadillo meant turtle-rabbit. The species name novemcinctus refers to the nine movable bands on the middle portion of their shell or carapace. Their common name, armadillo, is derived from a Spanish word meaning “little armored one.” Figure 1. Nine-banded Armadillo. Photo by author, 2014. Status Armadillos are considered both an exotic species and a pest.

    Field Guides Tour Report NEW ZEALAND 2011 Oct 27, 2011 to Nov 14, 2011 George Armistead & Andrew Crossland There must be a Wrybill in there somewhere! A huge flock of shorebirds takes flight at Miranda, one of NZ's premier shorebird sites. (Photo by guide George Armistead) Kia Ora, one and all! Our New Zealand 2011 adventure went off without a hitch. We arrived in Auckland fresh on the heels of the All Blacks victory in the Rugby World Cup, and found the kiwis in high spirits. This in spite of some anxiety over an upcoming national election, and an oil spill that had spoiled the shores of the Bay of Plenty. Combine these events with the recent earthquakes that had rocked Christchurch violently, and it indeed seemed a momentous time for those in New Zealand; residents and visitors alike. Perhaps blissfully oblivious to it all, the birds, thankfully, cooperated marvelously. New Zealand lived up to its reputation as a place harboring incredible, breath-taking scenery, and we enjoyed beautiful backdrops while soaking up sightings of unique strange landbirds, some of the world's rarest shorebirds, and of course a boatload of seabirds. Around Auckland, after tallying our first New Zealand Dotterels and Fernbirds, we went a-sea to visit the incomparable island of Tiritiri Matangi. We had many targets on this unique reserve, and were thankful to connect with nearly all of them. Nothing could top "Greg" the Takahe, but seeing some baby Blue (Little) Penguins in a nest and tallying a fantastic pair of Kokako, while being overrun with Tuis, Bellbirds, Stitchbirds and Saddlebacks was simply exhilarating.

  • New Zealand Rep 2015
    A glorious Yellow-eyed Penguin on its nesting grounds (Mark Van Beirs) NEW ZEALAND 26 OCTOBER – 14 NOVEMBER 2015 LEADER: MARK VAN BEIRS assisted by MARK AYRE and CHRIS GASKIN 1 BirdQuest Tour Report: NEW ZEALAND www.birdquest-tours.com New Zealand truly is a very special country for international birdwatchers. Although it has lost 58 endemic bird species since it was colonized by the Maori c1000 years ago, it still holds a splendid selection of forest endemics and without a doubt the most astounding variety of seabirds on our globe. We managed to see a very high percentage of these endemics and pride of place must certainly go to the four species of kiwi (out of five) that we managed to see at close range! The experience with the South Island Kiwi on a remote beach on Stewart Island will never be forgotten, and we also savoured to the full the smashing encounters with Little Spotted Kiwi on Tiritiri Matangi island, with the very rarely seen Great Spotted Kiwi at Arthur’s Pass and with the Okarito Kiwi at Okarito. The magnificent seabird spectacle of dozens of albatrosses, petrels, shearwaters and storm petrels at very close range on our different pelagics in the Hauraki Gulf, off Kaikoura and around Stewart Island were truly out of this world. Although some of the endemic landbirds now only occur on offshore islands or in some remote southern beech or podocarpus forests, we very much enjoyed the amazing dawn chorus of singing Tuis, Bellbirds, Saddlebacks and Robins. New Zealand is home to six endemic bird families: the Kiwis (Apterygidae), the New Zealand Parrots (Strigopidae), the New Zealand Wattlebirds (Callaeiidae), the Stitchbird (Notiomystidae), the New Zealand Wrens (Acanthisittidae) and the New Zealand Creepers (Mohuidae).
