Long-tailed Koel
Urodynamis taitensis
Large cuckoo with horizontal spots and streaking and a very distinctive long tail. Mainly found in native and exotic forests during the breeding season where one or more of its target host species reside: Whitehead, Yellowhead, and Pipipi. Breeds only in New Zealand before migrating to tropical Pacific islands for winter. Difficult to observe up close. Gives a distinctive loud ascending screech “zzhweeet” which can be heard during the day or night as it migrates. There is potential for confusion with New Zealand Falcon; note the Koel’s straighter bill and distinctive long tail.
Identification
The long-tailed cuckoo is approximately 40–42 cm in length, with a wingspan of approximately 47–52 cm, and weighs about 120 grams. It has broad pointed wings and a long tail that is softly rounded at the tip. Its beak is short and stout with a slightly hooked tip. It has brown barring to brown upperparts, and dark streaking to white underparts. Both males and females share similar features. A juvenile cuckoo is markedly different from the adult: it is spotted, with buff underneath and on the sides of the head and neck.<p>Adult. Top of head and hindneck, dark brown, boldly streaked buff. Supercilium, White's, bordered below by bold dark-brown eye stripe continuing downsides of neck, cheeks, chin, throat and foreneck, whites with thin brown stripes and fine black streaking on near neck and throat. The remainder of the upperparts are brown with white spotting on wing. Tail is tipped white. The underbody is white with course black brown streaking. Legs and feet are gray to green.<p>Long-tailed cuckoo have a loud and intense sound, a "shrill whistle"; it is sometimes called the "screamer".
Taxonomy
Urodynamis taitensis is most closely related to the channel-billed cuckoo (Scythrops novaehollandiae), which lives in Australia, Papua New Guinea and Indonesia, according to Sorenson and Payne (2005). Accordingly, it is not part of the Eudynamys genus (the true koels), with which it has previously been placed.

Range and habitat
Endemic to New Zealand, where they can be found on Little Barrier Island, the West Coast of the South Island, Nelson, and throughout the central North Island.<p>Long-tailed cuckoo prefer to live in forest on mainland and near shore or offshore islands, from sea level. in mountainous areas, more often on vegetated ridges than in valleys. Usually in dense, closed canopy of native forests dominated by beech Nothofagus, broadleaf species or podocarps or mixtures, with or without shrub layer. Usually surrounded by plantations of Pines (Pinus). Can be around other vegetation such as manuka Lepotospermum scoparium by rivers or forests or mountainous areas. Occasionally can be found in recreational parks, residential areas and gardens.<p>In New Zealand the cuckoos live mainly in native forest, particularly up in the canopy. They also live in exotic pine plantations, scrub, cultivated land and suburban gardens. In the Pacific islands they live in lowland forest, gardens and coconut plantations. Individuals are usually solitary.<p>The long-tailed cuckoo breeds only in New Zealand, where it is resident in the warmer months, from early October until February or March, sometimes April and occasionally later. The length of an average one-way journey from New Zealand to Polynesia is around 2500-3500 kilometers and thus travel over 6000 kilometers. For winter it migrates to islands right across the southern Pacific. It is found year-round on the Kermadec Islands, the Norfolk Island group and the Lord Howe Island group, which are subtropical islands part way between the New Zealand mainland and the tropical Pacific Islands. The spread of its winter distribution is extraordinarily wide, stretching almost 11,000 km from Palau in the west to Pitcairn Island. Over most of its winter range, it is known by the indigenous name, kārewarewa (or local variations of this). In spring, the bird's routes of migration would almost certainly have served to guide the Polynesian ancestors of Māori to find New Zealand.

Other Birds
Crimson-winged Woodpecker
Picus puniceus
Greenish medium-sized woodpecker with bright red wings and crown. Also note striking yellow crest, cream-speckled sides, and pale blue-gray “spectacles”. Male has a greener face than the female, and has a maroon “mustache” stripe. Similar to Checker-throated and Banded Woodpeckers, but note Crimson-winged’s red crown and greenish body. Inhabits both primary and secondary forests, from lowlands into lower montane areas, as well as plantations and logged tracts; favors areas with scattered and isolated tall trees. Forages on trunks and large branches in upperstory, often in distanced pairs or mixed flocks. Call is a high-pitched “kee-dee”, with the second note often being repeated several times, occasionally with a descending quality.
Black-browed Albatross
Thalassarche melanophris
A common and widespread albatross of the southern oceans; often seen from shore and ferries. Like other albatrosses, often scavenges at fishing boats. All plumages white-headed, often obvious at long distance (black brow only visible at close range). Adult has orange-yellow bill, brighter at the tip and thick black irregular underwing margins; 1st-year has dusky bill with black tip and solidly blackish underwings; mostly like adult in 3 years.
Lemon-breasted Seedeater
Crithagra citrinipectus
A small gray-brown seedeater with a lemon-yellow rump, white tail tips, and a boldly marked face with pale patches (white to lemon-yellow) above and below the eye. The throat and upper breast are lemon-yellow in the male and buff in the female. Pairs and small flocks occupy savanna, grassland, and palm savanna, where the species is partial to Ilala Palm. It forages on the ground and in small shrubs and grass. The similar Yellow-fronted Canary is yellower, has a broader eyebrow, and lacks wingbars and the vertical dark stripe below the eye.
