1998 Definitives Stamps Animals - Blackbird (Turdus Merula) Face Value ; 1 Luokka (Klass)
The Blackbird, Common Blackbird or Eurasian Blackbird (Turdus merula) is a species of true thrush which breeds in Europe, Asia, and North Africa, and has been introduced to Australia and New Zealand. It has a number of subspecies across its large range; a few of the Asian subspecies are sometimes considered as full species. Depending on latitude, the Blackbird may be resident, partially migratory or fully migratory.The male of the nominate subspecies, which is found throughout most of Europe, is all black except for a yellow eye-ring and bill and has a wide range of vocalisations; the adult female and juvenile have mainly brown plumage. This species breeds in woods and gardens, building a neat, mud-lined, cup-shaped nest. It is omnivorous, eating a wide range of insects, earthworms, berries, and fruits.Both sexes are territorial on the breeding grounds, with distinctive threat displays, but are more gregarious during migration and in wintering areas. Pairs will stay in their territory throughout the year where the climate is sufficiently temperate. This common species has given rise to a number of literary and cultural references, frequently related to its melodious song.
22.09.2006 Flora Mountain Avens (Dryas Octopelata) Face Value ; 1 st Class Size ; 34,5 x 24,5
Dryas octopetala (common names include mountain avens, white dryas, and white dryad) is an arctic-alpine flowering plant in the family Rosaceae. It is a small prostrate evergreen subshrub forming large colonies, and is a popular flower in rock gardens. The specific epithet octopetala derives from the Greek octo (eight) and petalon (petal), referring to the eight petals of the flower, an unusual number in the Rosaceae, where five is the normal number. However flowers with up to 16 petals also occur naturally.Dryas octopetala has a widespread occurrence throughout mountainous areas where it is generally restricted to limestone outcrops. These include the entire Arctic, as well as the mountains of Scandinavia, the Alps, Carpathian Mountains, Balkans, Caucasus and in isolated locations elsewhere. In Great Britain, it occurs in the Pennines (northern England), at two locations in Snowdonia (north Wales), and more widely in the Scottish Highlands; in Ireland it occurs on The Burren and a few other sites. In North America, it is found in Alaska most frequently on previously glaciated terrain and reaches as far south as Colorado in the Rocky Mountains. It is the official territorial flower of the Northwest Territories.The stems are woody, tortuous, with short, horizontal rooting branches. The leaves are glabrous above, densely white-tomentose beneath. The flowers are produced on stalks 3-10 cm long, and have eight creamy white petals. The style is persistent on the fruit with white feathery hairs, functioning as a wind-dispersal agent. The feathery hairs of the sea head first appear twisted together and glossy before spreading out to an expanded ball which the wind quickly disperses.It grows in dry localities where snow melts early, on gravel and rocky barrens, forming a distinct heath community on calcareous soils.
Blueberry - Vaccinium myrtillu Face Value ; 1 LK (KL) Size ; 27 x 38
Blueberry - Vaccinium myrtillu
Blueberries are flowering plants in the genus Vacinnium,Cyanococcus. The species are native only to North America. They are shrubs varying in size from 10 cm tall to 4 m tall; the smaller species are known as "lowbush blueberries", and the larger species as "highbush blueberries". The leaves can be either deciduous or evergreen, ovate to lanceolate, and from 1-8 cm long and 0.5-3.5 cm broad. The flowers are bell-shaped, white, pale pink or red, sometimes tinged greenish.
The fruit is a false berry 5-16 mm diameter with a flared "crown" at the end; they are pale greenish at first, then reddish-purple, and finally indigo on ripening. They have a sweet taste when mature, with variable acidity. Blueberry bushes typically bear fruit from May through October; "blueberry season" peaks in July, which is National Blueberry Month in the United States and Canada.
All species whose English common names include "blueberry" are currently classified in section Cyanococcus of the genus Vaccinium. Several other plants of the genus Vaccinium also produce blue berries which are sometimes confused with blueberries, mainly the predominantly European bilberry (Vaccinium myrtillus), which in many languages has a name that means "blueberry" in English. See the Identification section for more information.
Although blueberries are native to North America, they are now grown also in Australia, New Zealand and South American countries and are air-shipped as fresh produce to markets around the world.
Beginning in 2005, blueberries have been discussed among a category of functional foods called superfruits having the favorable combination of nutrient richness, antioxidant strength, emerging research evidence for health benefits and versatility for manufacturing popular consumer products.
