Hirvikärpänen (Wie heisst eigentlich die "Elchfliege"?) verbreitet sind immer weiter nördlich, bis hin nach Kuusamo und Pudasjärvi. Es ist gut 50 km weiter als zuvor. Grund: Klimaerwärmung.

Ich würde meinen, dass die Ausbreitung der Fliege nur bedingt mit Klimaerwärmung zu tun hat. In meiner 35 jährigen Erfahrung in Finnland, habe ich gesehen, wie die aus Russland kommende Fliege sich jedes Jahr um einige Kilometer weiter ausbreitete. Noch vor Jahren gab es in Häme keine Elchfliegen.

Deer keds travel north[/color]
Deer keds, also known as deer flies, have spread into more areas of Finland than ever this autumn, including parts of Lapland for the first time.

Researchers at the University of Oulu says deer keds, also known as deer flies, have spread into more areas of Finland than ever this autumn, including parts of Lapland for the first time.


Deer keds (Lipoptena cervi), which resemble ticks but are 6-7 millimetres long and have wings, have been spreading into Finland from Russia since the 1960s. They are now moving northward due to the milder climate, possibly threatening reindeer herds.

The deer-ked is an introduced species of biting fly originally found in Europe, Siberia, and Northern China. It is recorded in nature as a parasite on red deer, roe, elk, and sika deer in the Old World and on whitetail deer, elk, horses, cattle and humans in North America. Under laboratory conditions it will also feed on dogs, house mice, moles, monkeys, pigeons and domestic fowl.

On humans, the deer-ked will engorge on blood in 15 to 25 minutes. The bite is barely noticeable and leaves little trace at first. Within three days the site develops into a hard, reddened welt. The accompanying itch is intense and may last 14 to 20 days. 80 This reaction is probably the result of the body’s reaction to the fly saliva.

The insects breed by laying eggs under the skin of moose and deer.

The Oulu researchers say the best way to avoid attracting deer keds while in the forest is to wear light-coloured clothing and mesh head coverings.

Warm weather in Finland prevents birds from flying south

If the unusually warm weather in Finland has left outdoor skiiers and ice skaters out of luck, it has been a boon for bird watchers. According to Birdlife Finland many bird species have postponed their flight south until colder weather arrives.
A total of 160 bird species have been observed in Finland, and a couple of them have never even been seen in the country before.

The rarest bird species observed in December - the Isabelline Shrike and Hume's Warbler - have not previously been observed during winter months.

The land of a thousand - presently ice-free - lakes is still teeming with waterfowl. Hundreds of Canadian Geese and swans have delayed their migration south. Additionally there are more White Wagtail, Meadow Pipit and Hen Harriers than usual according to Birdlife.

However, there are fewer Fieldfares, Waxwings and Pine Grosbeaks than usual because they have difficulty finding food.
