Spring City Park ordinary Kingfisher reporter Wang Hongguang photography / > recently, this newspaper sent multiple photographers to shoot the winter birds in Ji'nan. Late December and January, although it was already in the depths of winter, there were still many birds living on the banks of the Yellow River, Xiaoqing River, wo Hushan Reservoir and Quancheng park. It seems that not only does Lao she love Ji'nan's winter, but birds also have a special liking for Ji'nan's winter.
little basin of spring water, birds like the winter in Ji'nan
"in the North China winter, and can have warm weather, Ji'nan really is a treasure." When Lao she wrote "winter in Ji'nan" in 1931, he had a sensitive experience that Ji'nan's winter was different from the warmth of other northern cities. Lao She said that Ji'nan was surrounded by mountains and lived in cradles of mountains. This is also a good point. There are large mountains in the south of the city, the magpie mountain in the northwest of the city, and the Huashan in the northeast of the city. According to the staff of the Forecast Department of the Shandong Meteorological Bureau, the temperature of the winter and the summer in Ji'nan is slightly higher than the surrounding city, and the topography of the small basin is a reason. In addition to the "thermal insulation" of Ji'nan, many mountains have also become the arena of birds. The city also includes Qianfo Hill, Quancheng Park, botanical garden, Forest Park and so on, so that the public can watch birds at close range.
there are many famous springs in Ji'nan. There are Daming Lake, five Longtan, Baotu Spring, moat, and the Yellow River on the north, and the water is rich in water. The shallow water area of the aquatic plants is the habitat of waterfowl. It is reported that springs come from deep strata, which are very little affected by the temperature, and the water temperature is relatively stable, maintained at 17~18 degrees Celsius throughout the year. As Laoshe said, "the water does not freeze, but it takes a little bit of heat on the green duckweed."
the mountains and rivers in Ji'nan provide the basic conditions for birds to survive. According to the professor of bird ecology in Shandong Normal University, the air temperature, water and woodland in Ji'nan can basically meet the survival of the birds. About 40 kinds of birds have been in the winter. There are winter birds in these birds, such as swans and wild goose, as well as the four seasons in Ji'nan, such as magpies, such as the magpie, the number and type of the two types of birds are equal. In addition to these natural conditions, the most affecting bird survival is human beings.
the human threat, the bird hiding to the less human reservoir
the track to be built every winter from November to January to watch the winter birds, and most comforting to him, "the birds are really less."
"birds generally go to places where people are few. When the area of Ji'nan reservoir water area increases, birds living in reservoirs are much more than the Yellow River." The raceway says it has been observed for decades that there were many birds at the edge of the Yellow River in the 50s, but now the river is narrowing, and human activities such as tourism development and sand digging make the birds less. The closed reservoirs in the western suburbs such as the jade Ting Lake and the Queshan reservoir are obviously more numerous because fewer people go.
the newspaper photographers were photographed in the the Yellow River sank pool, the the Yellow River bridge, and the south mountain mountain reservoir. The birds were found to be away from the waters of the crowd. The swans were two hundred or three hundred meters away from the shore. There are also many birds in Quancheng park. The recent shooting distance is to shoot sparrows, which is two or three meters apart.
water birds fear the ice forest birds are afraid of heavy snow
a lot of people are impressed with the swan's ballet dance drama, and some people do not understand the living habits of the swan. "One scene is that a group of dancers lie on the stage, and do not understand what is going on". "This is the life of water birds. The swans are water birds. They float on the surface when they rest."
water birds need large areas of ice free water. Aquatic organisms can be food and float on the surface. "I observed that when a surface of water ice, the unicy small pieces of water will be dense birds."
but he is not afraid that waterfowl can't spend the winter in Ji'nan. "There will always be a non freezing place when ice is frozen. When ice is in the shade, it may not be frozen to the sun." Birds will choose their own environment for survival. " When the ice is not frozen, the area of waterbirds is relatively dispersed, and when the water freezes, the waterbirds are concentrated in places where there is no ice. When the temperature is low and the aquatic life is reduced, waterfowl usually eat wheat seedlings.
the overwintering of woodland birds is mainly affected by the snow, such as the cold in 2012, the early and more snow under the snow, and the birds are concentrated in the vicinity of the higher temperature city and in the city. In the winter of 2013, the survival of woodland birds was large, so it was much more dispersed than in 2012. Track construction says birds that winter in Ji'nan need to nest. But in Ji'nan there are fewer, only some Mallard and half mouth duck nest.
Ji'nan is active in the winter of more than 40 birds
track construction. In winter Ji'nan still is active in more than 40 birds, and this year he found a rare long tail duck near the Xiaoqing River sink. In the past two years, there were about 45 swans in Longhu wetland and sink basin. Daming Lake also found 1 common cormorants in this year. According to the statistics of the track construction, the 40 kinds of Ji'nan winter birds belong to 11 orders, of which there are 12 species of wild goose, the big Swan and the long tailed duck all belong to this order. There are 500 to 700 wild goose in Yuqing lake and magpie mountain reservoir for many years. In addition, they are duck, green head duck, Green Wing duck, red linen duck, red neck duck, red head duck, green head ducks, and spotted autumn ducks. The common autumn duck can also be seen. There are 2 species of doves, the turtles of the necked neck and the turtles. There are about 10 species of
passerine, including magpies, gray magpies, white heads, gray starlings, bird finches, black tailed wax, blackheads, sparrows, sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, white sparrows, and white sparrows. At the water's edge, the public can see herring herons, middle egrets, egrets, night herons, Blackwater chickens and crest chickens.
in Daming Lake and five Longtan, there are two kinds of crepe and crested cocktail. Common Kingfisher can be seen in the waters of some parks. The owl shaped owl and the long owl are visible in the woodland. In the suburbs of Ji'nan, Falcon shaped kite, black wing kite and big fish can also be seen. "But the number of birds in Ji'nan is not as large as that in Weihai, Weifang and Dongying."
