Purple-crowned Plovercrest
Stephanoxis loddigesii
Medium-sized charismatic hummingbird with an iridescent green body and short, straight bill. Males have a violet-blue crest and are violet below with light gray flanks. Females have a less prominent crest, lack the violet belly seen on males, and have a prominent white spot behind the eye. Resembles Green-crowned Plovercrest, but males have a purple (not green) crest and has less extensive violet below. Female Purple-crowned Plovercrests have slightly larger white tips to the outer tail feathers than Green-crowned Plovercrest. Inhabits the understory of lowland and montane forests, light woodland and riparian forests.
Identification
The purple-crowned plovercrest is 8.5 to 9.5 cm (3.3 to 3.7 in) long. Males weigh about 3.7 g (0.13 oz). Both sexes have a shortish, straight, black bill. Adult males have a shaggy violet-blue crest. Their face, chin, and throat are brownish with a white spot behind the eye. Their upperparts yellowish green. Their lower throat to upper belly is blackish violet-blue and the rest of the underparts are gray. Their central two pairs of tail feathers are green and the rest green with a blackish band near the end and whitish tips. Adult females and juveniles have a much smaller crest. Their upperparts are also yellowish green and their underparts gray.
Taxonomy
The purple-crowned plovercrest and green-crowned plovercrest (Stephanoxis lalandi) were originally treated as separate species but in the mid-1900s were combined under the name "plovercrest" with the binomial S. lalandi. A study published in 2014 provided evidence that the original two-species treatment was correct. Taxonomists worldwide agreed and the two taxa were restored to species status. They are the only members of the genus and are monotypic.

Gyrfalcon
Falco rusticolus
Stocky beast of a falcon; ranges in color from strikingly white to silvery-gray to dark sooty-brown. Relatively long tail and broad wings with powerful flight. Generally darker above and paler below, with markings on the belly ranging from small and crisp to big and chunky. Breeds on cliffs on Arctic tundra; winters in large open areas. Scarce even on breeding grounds. Bulkier and shorter-winged than Peregrine Falcon with a more diffuse face pattern and silvery undersides on flight feathers. Feeds on birds and mammals.
Gentoo Penguin
Pygoscelis papua
Attractive, medium-sized penguin that is rarely seen away from well-known colony sites. Appearance is distinctive with white “headphones” and a lipstick-orange bill unlike any other penguin. Striking head and bill pattern also make it one of the easiest penguins to identify when seen swimming at sea. Nests in small colonies and occurs around King and Magellanic Penguins in northern areas of its range, as on the Falklands.
Pink Robin
Petroica rodinogaster
Small, plump Australian robin. Male very dark gray above and on throat, with lovely pink breast and belly. Tail completely dark, unlike Rose Robin. Female brown above, paler below, sometimes tinged pinkish. Breeds in very wet dense rainforest gullies in Tasmania and Victoria, sometimes in other more open habitats in winter.
