Jilin has "long necks and old people", often walking by the water, and can squat for several hours in order to catch a fish to eat

After the ecological environment has gradually improved, in addition to letting us feel the beauty of ecology, the probability of encountering wild animals is also increasing. A farmer in Da'an City, Jilin Province recently went to the field to mow grass and found a big bird on the road not far away in an unusual state, so he went in to see it. Who knew that the big bird would not fly away, guessing that the wings may be injured. After the animal protection department and other relevant personnel arrived at the scene, they were identified and found that the big bird was a wild gray stork, also known as gray heron and heron, which belongs to the second-class national protected animal. walk on the ground. Grey storks are not uncommon in my country. They exist in most provinces of the country, especially in the southern regions. As resident birds, they do not migrate and can be seen all year round. It is not the first time that the gray stork has broken into the living area of ​​human beings. As early as April, a large bird fell from the sky in a farmer's home in Xiao County, Anhui Province. After the event, it was identified as a gray stork. stork. After careful inspection by the staff, it was found that the bird had no trauma. After resting for a period of time, its mental state also improved. At the same time, it has the ability to fly. It is guessed that the reason why it fell into the farmer's yard may be caused by the lack of physical strength after flying for too long. of.

The legs are long and the neck is long, and the wings are spread out to 1.5 meters.

The gray stork is a heron family, and it is also a type species of the heron. , widely distributed in the wetlands of Eurasia and Africa, is a common wading bird. Their size is relatively large, the adult body is about 3.5 kg, and the wings can reach 1.5 meters. The feathers on the gray stork are mostly gray-brown. The top of the head and the neck of the male bird are white, and the sides of the top of the head and the pillow are black. There are four slender feathers in the crest, like a small braid. As a large water bird, the grey stork has long legs and a long neck and a slender bill. Like most herons, the grey stork is slender. As a water bird, the grey stork mainly inhabits the swamps, lakes, rivers, tidal flats, rice fields and other environments in low mountain and plain areas, among which shallow waters are their main activity areas. Grey storks usually live in pairs or small groups, and they also forage alone in shallow waters, where their slender legs facilitate foraging in such environments. It mainly feeds on small aquatic animals such as small fish, small shrimp, and loach, and also eats some insects. Early morning and early evening are their most active times of the day. When not eating, grey storks will often stand on one foot in shallow water, with the other foot tucked under the belly, and the neck tucked between the shoulders. Just using this position, standing in the water for hours at a time, like a chicken.

Gray storks have great foraging skills and are known as "long-necked old men"

When gray storks are foraging, there are many ways, they will According to different situations, rationally adopt the most effective predation method. For example, sometimes they will stand still in the water, staring at the surface of the water, and when small fish and shrimp pass by, they will quickly stretch their necks to peck at the opportunity. Sometimes they would walk slowly in the shallow water while looking for fish and shrimp, and when they found them, they would stretch their necks and peck them down. If the fish condition is not good, the grey stork will also adopt a trapping method to attract small fish. According to legend, in Malaysia, the grey stork first flew a few laps on the water to observe the fish in the water, and then flew into the grass on the shore, picked up some small bugs and threw it on the water, attracting many small fish to feed in front of it, this effect is quite In "hitting the nest". Once the small fish gather together, the grey stork will quickly peck, feeding the small fish one by one into their stomachs. The grey stork is a relatively patient bird. When they forage in the water, if the fish is not in good condition, they have another great trick, which is to wait. The grey stork would pick a spot and just stand there, waiting for hours until the fish came. Just like a fisherman, no matter how long it takes, he doesn't change his position until he catches a fish. After the habit of the gray stork was known, it was nicknamed "the long-necked old waiter". Like many solitary predators, they like to hide and let their prey approach them before jumping out to kill them.

Drowning weasels, grey storks are stronger than expected

It is well known that, with the exception of some raptors, most birds face terrestrial predators No parry advantage. The mustelidae animals on land are notoriously fierce and are known for being good at "small and big". For example, a small fisherman can kill a Canadian lynx, and a small yellow-throated mink can also hunt down the forest musk deer . The weasel is also a very aggressive little predator, but it can't handle the grey stork. In March 2015, photographer Jonathan captured the scene of a battle between a weasel and a grey stork at the Isle of Sheppey Nature Reserve in Kent, England, and the battle ended with the weasel being eaten. At that time, a weasel was biting the gray stork's mouth, and it seemed that it was eyeing the gray stork and wanted to kill it. I saw the grey stork shaking its head desperately, trying to get rid of the weasel, but the bite was too tight, and the grey stork couldn't break free after a few tries. If it goes on like this for a long time, the gray stork will inevitably become the weasel's meal. At this time, the gray stork had a plan, it came to the water's edge, and then immersed its mouth and the weasel in the water. The weasel may not have thought that the grey stork has such a trick. After a while, the weasel was drowned. Although the grey stork is a kind of water bird and mostly feeds on fish and shrimp, it does not refuse the food brought up, and eats the drowned weasel on the spot. The gray stork, which was originally thought to be used as food, actually achieved a counter-kill. It seems that it is stronger than we thought. The gray stork has a wide distribution range in my country, both in the north and south. In northern regions, they are migratory birds and have the habit of migration; in southern regions, they are resident birds and do not migrate. During the breeding season, grey storks will choose a big tree or reeds to build their nests near the water. They like to get together to "build houses". Sometimes we can see that there are more than a dozen on a big tree. The nest of the grey stork is still quite spectacular. Follow me and make a friend who understands animals.
