Erect-crested Penguin
Eudyptes sclateri
Medium-sized crested penguin, endemic to New Zealand. Note the distinct broad yellow eyebrow rising over the eye to form a stiff brush-like crest. Also look for pale blue skin at the base of the bill. A subantarctic breeder, with main colonies on Bounty and Antipodes Islands. Disperses widely at the end of breeding season. A small number molt on the east coast of the North and South Islands in the fall. Forms small groups at sea. Voice a low-pitched booming bray. Distinguished from Snares and Fiordland Penguins by pale white-blue skin at bill base and less “V-shaped” crest when seen head-on.
Identification
This is a small-to-medium-sized, yellow-crested, black-and-white penguin, at 50–70 cm (20–28 in) and weighing 2.5–6 kg (5.5–13.2 lb). The male is slightly larger than the female and as in most crested penguins has a larger bill. It has bluish-black to jet black upper parts and white underparts, and a broad, bright yellow eyebrow-stripe which extends over the eye to form a short, erect crest. With a mean body mass in males of 6.38 kg (14.1 lb) (sample size 22) and females of 5.4 kg (12 lb) (sample size 22), the erect-crested penguin is the largest of the crested penguin species and as the fourth heaviest extant penguin, being nearly as heavy on average as the gentoo penguin.<p>Its biology is poorly studied and only little information about the species has emerged in the past decades. The only recent study conducted on the Antipodes Islands focused on aspects of the mate choice. Research on the species is hampered by logistics and restrictive permitting by the New Zealand Department of Conservation.<p>It presumably feeds on small fish, krill and squid like other crested penguin species.<p>The binomial commemorates the British zoologist Philip Lutley Sclater.

Range and habitat
Erect-crested penguins breed on the Bounty and Antipodes Islands. Previous records of small breeding populations have also been reported from Campbell Island and the Auckland Islands; in the 1940s a breeding pair was documented on the Otago Peninsula on the New Zealand mainland. The species spends extended times at sea during the pre-moult period (February–March) as well as over the winter months (March–August). Individuals have been found as far away as the Falkland Islands and it is also a vagrant to Argentina, Antarctica and Australia.<p>Erect-crested penguins nest in large colonies on rocky terrain. On the Antipodes Islands, the penguins breed in mono-specific colonies or sometimes sympatrically with Southern Rockhopper penguins. On the Bounty Islands, Erect-crested penguins breed in large mixed colonies with Salvin's albatross. Erect-crested penguins breed in two-egg clutches from the months between September to late January. The first egg to be laid is typically 25% to 70% smaller than the second egg. The extreme difference in egg sizes has demonstrated asynchronous incubation habits, with the larger egg being granted more accommodation and priority than the smaller egg.

Antarctic Prion
Pachyptila desolata
A medium-sized prion with a noticeable dark “M'' stretched across their back from wingtip to wingtip noticeable in flight. They breed on Antarctic and subantarctic islands in the South Indian, Southern and South Atlantic Oceans and are widespread and abundant at sea around these areas. Regular visitor to New Zealand and Southern Australia during the austral winter. Very similar to other prion species, especially Salvin’s prion, with the Antarctic prion having a slightly brighter blue bill with straighter sides and a larger nail at the tip.
Rufous-bellied Helmetshrike
Prionops rufiventris
A boldly patterned helmetshrike of lowland forests, often seen in small vocal groups. The bill is red and the head and chin are overall silvery gray. Has a black neck band and black wings, back, and tail. The chest is white and the belly, vent, and legs are reddish. Similar to the Red-billed Helmetshrike, with which it co-occurs locally in Cameroon, but Rufous-bellied Helmetshrike can be identified by its silvery gray chin and head (including below the eye) and the more extensive reddish coloration on its belly. Calls consist of liquid whistles and repeated grating “chew-two” calls.
Mikado Pheasant
Syrmaticus mikado
A stunning pheasant species endemic to Taiwan, the male a rich slaty blue with white markings and red facial skin, the female rich brown with extensive pale feather edges. Generally retiring, foraging quietly in the undergrowth of montane forests, but occasionally seen in the open, particularly in places where fed. Usually seen singly, in pairs, or in small family units (female with young). In breeding season, males drum with wings and give shrill whistling calls. Male lacks white back and tail of Swinhoe’s Pheasant; female has dark bill, grayish legs, pale markings below, and graduated, pointy tail, unlike female Swinhoe’s.
