The Gyrfalcon (Falco rusticolus), also spelled Gyr Falcon, sometimes Gerfalcon, is the largest of all falcon species. The Gyrfalcon breeds on Arctic coasts and islands of North America, Europe and Asia. It is mainly resident, but some Gyrfalcons disperse more widely after the breeding season, or in winter[1].
The bird's common name comes from French gerfaucon, and in mediaeval Latin is rendered as gyrofalco. The first part of the word may come from Old High German gîr (cf. modern German Geier), "vulture", referring to its size compared to other falcons, or the Latin gȳrus ("circle", "curved path") from the species' circling as it searches for prey, unlike the other falcons in its range[2]. The male gyrfalcon is called a gyrkin in falconry.
Its scientific name is composed of the Latin terms for a falcon, Falco, and for someone who lives in the countryside, rusticolus.
Plumage is very variable in this highly polymorphic species: the archetypal morphs are called "white", "silver", "brown" and "black" though coloration spans a continuous spectrum from nearly all-white birds to very dark ones.
The Gyrfalcon is a bird of tundra and mountains, with cliffs or a few patches of trees. It feeds only on birds and mammals. Like other hierofalcons, it usually hunts in a horizontal pursuit, rather than the Peregrine's speedy stoop from a height. Most prey is killed on the ground, whether they are captured there or, if the victim is a flying bird, forced to the ground. The diet is to some extent opportunistic, but a majority of breeding birds mostly rely on Lagopus grouse. Avian prey can range in size from redpolls to geese and can include gulls, corvids, smaller passerines, waders and other raptors (up to the size of Buteos). Mammalian prey can range in size from shrews to marmots (sometimes 3 times heavier than the assaulting falcon), and often includes include lemmings, voles, ground squirrels and hares. They only rarely eat carrion.
The Gyrfalcon is the official bird of Canada's Northwest Territories.

A species of wader in the Haematopodidae family. It is endemic to New Zealand. The Maori name is torea-pango. They are also known as 'red bills'. "Variable" refers to the frontal plumage, which ranges from pied through mottled to all black. They are polymorphic meaning they have different genetic variants. Blacker birds are more common in the south. All Stewart Island variable oystercatchers are black. They have pink legs, an orange eye ring and red beaks. They are often seen in pairs on the coast all around New Zealand. During breeding, the pair will defend their territory, sometimes aggressively. Once mated pairs rarely divorce. After breeding they may be seen within flocks, or on the edges of flocks, of black and white South Island Pied Oystercatcher (SIPO) which also have vivid orange beaks. After breeding they may even form small flocks of their own. Males are around 678 grams and females slightly larger at around 724 grams. Variables can be identified as they are slightly larger than the SIPO - SIPO are around 550 grams. Occasionally totally black but if they are pied (black and white) they can be easily confused with SIPO. The variable species has less definition between the black and the white area, as well as a mottled band on the leading edges of the underwing. Variables also have a smaller white rump patch which is only a band across the base of the tail rather than a wide wedge shape reaching up to the middle of the back as in the SIPO. When mottled they are sometimes called 'smudgies'. They feed on molluscs, crabs and marine worms. After heavy rain, they sometime go inland in search of earthworms. They can open a shellfish by either hammering a hole in it or getting the bill between the two shells (of a bivalve) and twisting them apart. They breed in North Island, South Island, Stewart Island, and Chatham Islands. They do not breed inland or beside rivers although the SIPO does. They nest on the shore between rocks or on sand dunes by making a scrape out of the sand or shingle, sometimes lined with some seaweed. When in flight they make a high pitched 'kleep kleep' sound. They usually lay 2-3 eggs but they can lay up to 5. The eggs are typically stone coloured with small brown patches all over. Eggs hatch in 25-32 days. Chicks are well camouflaged by their colour and can fly in about 6 weeks. The bird lives up to about 27 years.

Morphologically highly polymorphic species from Puebla and Oaxaca states in Mexico, where it is found wild at
elevations from 4500 to 7500 feet.
It found traditional use in the making of Agave wine (pulque) and the spirit Bacanora in Mexico.
The size of the whole plant, the characteristic number of leaves as well as shape and spininess all vary a lot. Forms like this, with large numbers of nearly orbicular leaves are popular in cultivation. Some young plants sucker freely but they stop doing so as they mature. They can take ten years to flower, and then the whole rosette dies.

A excellent night at a beautiful preserve in the Jersey pines, the night started off with a few light sprinkles of rain, followed by a beautiful rainbow, some grilling for dinner, a great variety of moths, and the night ending with Great Horned, and Barred Owls!
This expansive property, New Jersey Conservation Foundation's largest, encompasses almost 14 square miles in the heart of the New Jersey Pine Barrens. It is accessible by a network of sandy roads that wind though pitch pine forest and blueberry fields, and run along the preserve’s cedar swamp, shallow lakes and pristine tributaries of the West Branch of the Wading River.
Four new trails totaling nearly 21 miles were recently cleared and blazed. Some are hikers-only footpaths, while others are multi-use trails that are open to bicyclists and horseback riders as well as hikers.
A former cranberry farm, the property was purchased by New Jersey Conservation Foundation in December 2003 after the owner decided he wanted it to be protected forever as a nature preserve. NJCF began an ambitious fund-raising campaign and was able to cover most of the property’s cost.
The property is a rare ecological treasure for the East Coast of the United States, containing some of the most beautiful wetlands in the Pine Barrens and providing critical habitat to more than 50 rare, threatened or endangered species.
Arescus species found inside rolled leaf shoots of Heliconia, El Chaco, Napo, Ecuador, 1650 meters altitude. The genus is exceptionally polymorphic.
Consensus Bayesian phylogeny of the Daphnia species complex based on the mitochondrial COX1 gene.The alignment contains 52 sequences of length 552 nt with 151 polymorphic positions of which 112 are phylogenetically informative. Nine of the 12 lineages in the Daphnia pulex species complex, including all three South American lineages, are represented. The tree is rooted through the midpoint. Numbers at the nodes are Bayesian posterior probabilities and are not shown if less than 0.80. Branch colors correspond to continents as follows: green = Europe, blue = North America, red = South America. Individual CT-18 was collected from Connecticut, USA.
Army ants, in the family Formicidae, are speciose and abundant in the tropical forest. There are around 150 species, all of which are characterized by large colonies, almost exclusive carnivory, and polymorphic workers, such as the soldier pictured above.
This specimen was collected as it entered its colony's subterranean bivouc, which is a cluster of ants clinging together. The ants typically pour out of the bivouac at dawn, and form a large raiding colony. They fan out at a distance of up to 50m from the bivouac, and then proceed to advance in a fan-shaped raiding front. Any animals (arthropods mostly) encountered are quickly subdued and brought back to the nest cache.
