The Australian wood duck, maned duck or maned goose (Chenonetta jubata) is a dabbling duck found throughout much of Australia. It is the only living species in the genus Chenonetta. Traditionally placed in the subfamily Anatinae (dabbling ducks), it might belong to the subfamily Tadorninae (shelducks); the ringed teal may be its closest living relative.
This 45–51 cm duck looks like a small goose, and feeds mostly by grazing in flocks. The male is grey with a dark brown head and mottled breast. The female has white stripes above and below the eye and mottled underparts. Both sexes have grey wings with black primaries and a white speculum. Juveniles are similar to adult females, but lighter and with a more streaky breast.
The Australian wood duck is widespread in Australia, including Tasmania. It is found in grasslands, open woodlands, wetlands, flooded pastures and along the coast in inlets and bays. It is also common on farmland with dams, as well as around rice fields, sewage ponds and in urban parks. It will often be found around deeper lakes that may be unsuitable for other waterbirds' foraging, as it prefers to forage on land.
The Australian wood duck eats grasses, grains, clover and other herbs, and occasionally, insects. It is rarely seen on open water, preferring to forage by dabbling in shallow water, or in grasslands and crops. They nest in cavities in trees or in nest-boxes above or near water. Nests are made with a pile of down. It lays 9–11 cream-white eggs, similar to the Mandarin ducks.
The female incubates them while the male stands guard.Once the ducklings are ready to leave the nest, the female flies to the ground and the duckling will leap to the ground and follow their parents. Like Mandarin drakes, the males also secure their ducklings closely along with the females.
Australian wood duck is widespread in its range. This species has benefited from agriculture developments, with creation of dams and pools. It is classified as a game bird, and killed by licensed hunters. This species is not threatened, and numbers are stable.

Victoria amazonica is a species of flowering plant, the largest of the Nymphaeaceae family of water lilies. It is the National flower of Guyana. The species has very large leaves, up to 3 m in diameter, that float on the water's surface on a submerged stalk, 7–8 m in length. The species was once called Victoria regia after Queen Victoria, but the name was superseded.
V. amazonica is native to the shallow waters of the Amazon River basin, such as oxbow lakes and bayous. It is depicted in the Guyanese coat of arms. The flowers are white the first night they are open and become pink the second night. They are up to 40 cm in diameter, and are pollinated by beetles. This process was described in detail by Sir Ghillean Prance and Jorge Arius. It is the largest waterlily in the world.
The spectacular flowers are relatively short-lived, lasting only 48 hours or so. The flower is white the first evening it opens, attracting beetles with a sweet pineapple-like scent and with heat from a thermochemical reaction. At this stage the flower is female, and is open to receiving pollen picked up by the beetles on other plants. As they bumble around inside the flower they transfer pollen to the stigmas and fertilisation takes place. Meanwhile the flower shuts, trapping them until the next evening.
During the following day the plant changes from female to male: The anthers mature and start producing pollen. When the flower reopens on the second evening it has changed colour to purplish red and no longer emits attractive scent or heat. The beetles, dusted with their pollen, fly off to find another white flower on a different plant (each plant only ever has one white flower at a time), where the process is repeated. The flower then closes up and sinks below the surface of the water, its mission accomplished.

Yellowjacket or Yellow jacket is the common name in North America for predatory social wasps of the genera Vespula and Dolichovespula. Members of these genera are known simply as "wasps" in other English-speaking countries. Most of these are black and yellow like the eastern yellowjacket Vespula maculifrons and the aerial yellowjacket Dolichovespula arenaria; some are black and white like the bald-faced hornet, Dolichovespula maculata. Others may have the abdomen background color red instead of black.
They can be identified by their distinctive markings, their occurrence only in colonies, and a characteristic, rapid, side-to-side flight pattern prior to landing. All females are capable of stinging. Yellowjackets are important predators of pest insects.

Ireland (Irish: Éire; Ulster-Scots: Airlann) is an island in the North Atlantic, often called "The Emerald Isle". It is separated from Great Britain to its east by the North Channel, the Irish Sea, and St George's Channel. Ireland is the third-largest island in Europe. Politically, Ireland is divided between the Republic of Ireland (officially named Ireland), which covers five-sixths of the island, and Northern Ireland, which is part of the United Kingdom, in the northeast of the island.
In 2011, the population of Ireland was about 6.4 million, ranking it the second-most populous island in Europe after Great Britain. Just under 4.6 million live in the Republic of Ireland and just over 1.8 million live in Northern Ireland. The island's geography comprises relatively low-lying mountains surrounding a central plain, with several navigable rivers extending inland.
The island has lush vegetation, a product of its mild but changeable climate which is free of extremes in temperature. Thick woodlands covered the island until the Middle Ages. As of 2013, the amount of land that is wooded in Ireland is about 11% of the total, compared with a European average of 35%. There are twenty-six extant mammal species native to Ireland. The Irish climate is very moderate and classified as oceanic. As a result, winters are milder than expected for such a northerly area. However, summers are cooler than those in Continental Europe. Rainfall and cloud cover are abundant.
