My explanation for the moon illusion - position of pupil on lens
The Moon illusion is an optical illusion in which the Moon appears larger near the horizon than it does while higher up in the sky. This optical illusion also occurs with the sun and star constellations. It has been known since ancient times, and recorded by numerous different cultures. The explanation of this illusion is still debated.
My theory is it is to due to the curvature of the lens of the eye.
It could be that When an object is seen through the lens, the curvature of the eye means that the object is different size on different parts of the lens, or that that as the pupil moves up and down on the eye. As you lift your head up to see the moon in the sky. You normally raise your pupils up to see this. This means they are at a different position on the eye. So it will have a different position on the eye. I am sure if you life your head up to see somthing with your pupils pointing up things seem smaller than if you lift your head up to look with your pupil in the middle of your eye.
On their other hand it might be to do with the rod, or cones nerve cells.

Wildfowl
Wildfowl are the biological family called Anatidaethat includes ducks, geese and swans. The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica and on most of the world's islands and island groups. These are birds that are adapted through evolution for swimming, floating on the water surface, and in some cases diving in at least shallow water. (The Magpie Goose is no longer considered to be part of the Anatidae, but is placed in its own family Anseranatidae.) The family contains around 146 species in 40 genera. They are generally herbivorous, and are monogamous breeders. A number of species undertake annual migrations. A few species have been domesticated for agriculture, and many others are hunted for food and recreation.

Anserinae
The Anserinae is a subfamily in the waterfowl family Anatidae. It includes the swans and true geese. Under alternative systematical concepts, it is split into two subfamilies, the Anserinae containing the geese, while the Cygninae contain the swans.
A number of other waterbirds, mainly related to the shelducks, have goose as part of their name; see the family page at Anatidae and the goose page for these.

Carl Linnaeus
Carl Linnaeus (Latinized as Carolus Linnaeus, 23 May [O.S. 12 May] 1707 – 10 January 1778) was a Swedish botanist, physician, and zoologist, who laid the foundations for the modern scheme of binomial nomenclature. He is known as the father of modern taxonomy, and is also considered one of the fathers of modern ecology.
Linnaeus was born in the countryside of Småland, in southern Sweden. His father was the first in his ancestry to adopt a permanent last name; prior to that, ancestors had used the patronymic naming system of Scandinavian countries. His father adopted the Latin form name Linnaeus after a giant linden tree on the family homestead. Linnaeus got most of his higher education at Uppsala University and began giving lectures of botany there in 1730. He lived abroad between 1735–1738, where he studied and also published a first edition of his Systema Naturae in the Netherlands. He then returned to Sweden where he became professor of botany at Uppsala. In the 1740s, he was sent on several journeys through Sweden to find and classify plants and animals. In the 1750s and 60s, he continued to collect and classify animals, plants, and minerals, and published several volumes. At the time of his death, he was renowned throughout Europe as one of the most acclaimed scientists of the time.

Uppsala is the capital of Uppsala County and the fourth largest city of Sweden with 140,000 inhabitants.
Located about 70 km north of the capital Stockholm, it is also the seat of the Uppsala Municipality. Since 1164, Uppsala has been the ecclesiastical center of Sweden, being the seat of the Archbishop of the Church of Sweden. Founded in 1477, Uppsala University is the oldest center of higher education in Scandinavia. Situated on the fertile Uppsala flatlands of muddy soil, the city features the small Fyris River (Fyrisån) flowing through the landscape surrounded by lush vegetation. Parallel to the river runs the glacial ridge of Uppsalaåsen, at an elevation of circa 30 metres the site of Uppsala's castle from which large parts of the town can be seen. The central park Stadsskogen stretches from the south far into town, with opportunities for recreation for many residential areas within walking distance.

This is the Fastest Bird in North Wales
This is the Fastest Bird in North Wales
This is a Red-breasted Merganser. These are claimed by some to be the fastest birds in level flight. Although some claim the White-throated Needletail is faster. This is possibly the fastest bird in Wales in level flight. This video was taken on the Conwy River Llanrwst on April the 16th 2010.

Black swansas a species
Black swans were first seen by Europeans in 1697, when Willem de Vlamingh's expedition explored the Swan River, Western Australia.
The black swan was described scientifically by English naturalist John Latham in 1790. It was formerly placed into a monotypic genus, Chenopis.
The common name ‘Swan’ is a gender neutral term, but ‘cob’ for a male and ‘pen’ for a female are also used, as is ‘cygnet’ for the young. Collective nouns include a ‘bank’ (on the ground) and a ‘wedge’ (in flight). Black Swans can be found singly, or in loose companies numbering into the hundreds or even thousands.

Tundra Swan
The Tundra Swan (Cygnus columbianus) is a small Holarctic swan. The two taxa within it are usually regarded as conspecific, but are also sometimes[1] split into two species, Cygnus bewickii (Bewick's Swan) of the Palaearctic and the Whistling Swan, C. columbianus proper, of the Nearctic. Birds from eastern Russia (roughly east of the Taimyr Peninsula) are sometimes separated as the subspecies C. c. jankowskii, but this is not widely accepted as distinct, most authors including them in C. c. bewickii. Tundra Swans are sometimes separated in the genus Olor together with the other Arctic swan species.
Whooper Swans
Whooper swans require large areas of water to live in, especially when they are still growing, because their body weight cannot be supported by their legs for extended periods of time. The whooper swan spends much of its time swimming, straining the water for food, or eating plants that grow on the bottom.
Whooper swans have a deep honking call and, despite their size, are powerful fliers. Whooper swans can migrate many hundreds of miles to their wintering sites in northern Europe and eastern Asia.http://muteswanbook.blogspot.com/
Whooper Swan
The Whooper Swan (Cygnus cygnus) is a large Northern Hemisphere swan. It is the Eurasian counterpart of the North American Trumpeter Swan.
