investigation of a mortality cluster in wild adult yellow-eyed penguins (megadyptes antipodes) at otago peninsula, new zealand.we investigated an epidemic mortality cluster of yellow-eyed penguins (megadyptes antipodes) that involved 67 moribund or dead birds found on various beaches of the otago peninsula, new zealand, between january 21 and march 20, 2013. twenty-four carcases were examined postmortem. histological lesions of pulmonary, hepatic and splenic erythrophagocytosis and haemosiderosis were found in 23 of 24 birds. fifteen birds also had haemoglobin-like protein droplets within renal tubular epithelial cells. ...201627919180

novel morphological and molecular data for corynosoma hannae zdzitowiecki, 1984 (acanthocephala: polymorphidae) from teleosts, fish-eating birds and pinnipeds from new zealand.the polymorphid acanthocephalan, corynosoma hannae zdzitowiecki, 1984 is characterised on the basis of newly collected material from a new zealand sea lion, phocarctos hookeri (gray), and long-nosed fur seal, arctophoca forsteri (lesson) (definitive hosts), and from stewart island shags, leucocarbo chalconotus (gray), spotted shags, phalacrocorax punctatus (sparrman) and yellow-eyed penguins, megadyptes antipodes (hombron & jacquinot) (non-definitive hosts) from new zealand. specimens are descri ...201727765681
prevalence of leucocytozoon spp, in the endangered yellow-eyed penguin megadyptes antipodes.yellow-eyed penguins on stewart island were identified with a leucocytozoon spp. of a novel lineage in association with a high regional incidence of chick mortality (n=32, 100% mortality) during the november 2006 to january 2007 breeding season. fourteen chicks from stewart island were examined post-mortem and histologically for leucocytozoon infection. in addition, a survey of blood to detect leucocytozoon spp. infections using pcr was performed on 107 yellow-eyed penguins from 4 distinct nesti ...201020557665
annual cycle of sex steroids in the yellow-eyed penguin (megadyptes antipodes) on south island, new zealand.the yellow-eyed penguin (megadyptes antipodes) is a rare penguin restricted to the south island and some offshore islands of new zealand. it is the least colonial of the penguins but shares with many other penguins a distinct breeding season with a short, synchronised period of egg-laying. blood samples were collected throughout the year from yellow-eyed penguins on the otago peninsula, south island in order to characterise relationships between steroid hormone levels and events of the breeding ...19948045361
