In recent days, Changchun Park in Changchun City has brought a group of rare visitors, white-winged cross-billed finches, which has attracted many birdwatchers to rush to visit. Perhaps, they have already made their home here, but they have just been discovered. There are two species of cross-billed finches in the world: the red-billed finch and the white-winged cross-billed finch, also known as the cross-beaked bird and the green-beaked bird. Often gregariously. In Changchun, it is also fortunate to see white-winged interlocutors.
According to an old man who often exercises here, these birds are here in winter. Are they wintering here?
According to the data, the white-winged cross-billed finch is distributed in the northeast, Hebei and other places in the Chinese mainland. It is found in montane coniferous forests and is also found in mixed coniferous and broad-leaved forests. The total length is about 15 cm. It's about the size of a sparrow. The male is scarlet throughout, with nearly black wings and tail, and a white spot on the wings. This is her most recognizable feature.
Their lower abdomen is white and their faces are dark brown. The female has dark green plumage and a grey face. There are also two white spots on the wings. The flight is fast and undulating. It can be eaten upside down, and the food is the seeds of pine and fir. This is good for them to have a very peculiar mouth, the upper and lower parts of the mouth intersect horizontally, which helps it to knock the pine cones open and eat the seeds inside.
It is said that the distribution of white-winged cross-billed finches is relatively widespread in the northern hemisphere, but it is extremely rare. Once it appears, it becomes the focus. A few years ago, Beijing Jingshan Park also appeared, attracting many people to watch.
I have observed that the biggest feature of the white-winged cross-billed finches in Changchun Park is that they are not afraid of people. When a person is only two meters from her closest distance, it does not fly either. In my more than ten years of bird shooting experience, it is the bird that is least afraid of people. A few times, I saw them burying their heads in the grass to eat, and there were many people around them, and they turned a blind eye, still going their own way, giving people the feeling of trusting human beings. I hope that humanity will not live up to this trust. Whether it's birdwatchers or bird shooters, as well as the general public, don't hurt them.
It was breeding season, and she was particularly sensitive to the voices of her companions. Some bird shooters use bird traps to release the same kind of call, and it actually hears the sound and moves, turning around the birdman. This behavior is very bad.
It was the female bird, by contrast, eclipsed
Some sources say that the sparrow is not born with such a mouth. When they were still chicks, the tips of the upper and lower beaks did not intersect, nor could they bite through the pine nuts, but could only be fed by adult birds. When the chicks grow up, their beaks become like adult birds and they are free to eat pine nuts.

Shake the hair
The birds are still being fed, indicating that these birds may have been born in Changchun Park
It's like feeding the birds chewed food
The main diet of the white-winged interlocutor is pine seeds or the seeds of fir trees
They often pick up pine nuts on the ground
Their ability to sniff pine nuts is far beyond that of us humans. We often use a lot of force to sniff pine nuts, but sometimes we can't open them, but they are not long in the mouth, and the pine nuts are separated.
Spit out the skin and only the nuts are left in the mouth
Pine nuts stuck to the mouth
One might ask that it pecks at a large number of pine and fir seeds every year, and the harm will be great. In fact, the sparrow always pecks down the pine tower first, or steps on the branch with its foot, so that the pine tower falls directly to the ground, and then pecks at the scales outside the pine tower to eat the pine nuts. At this time, some pine nuts are not eaten, but scattered on the ground, and will sprout and grow in the next year. It inadvertently spread seeds for these plants as well.
