Yesterday at 12:59, Mr. Zhu called: My family lives on the 13th floor of the Wendingyuan Community in the west of the city, just when I looked down at the construction site outside the community on the balcony, I found that there were actually two magpies on the crane to build a nest. The crane is also thirteen or fourteen stories high, I didn't expect to have a bird's nest, I watched two magpies fly in and out, very interesting. I took a picture and posted it to your WeChat in a moment.
Reporter Ge Yaqi photography report: Mr. Zhu's photo was taken with a mobile phone, but unfortunately the distance is too far, and it is still not clear to put it to the maximum. Yesterday afternoon, I rushed to Mr. Zhu's house to see if I could get a clearer picture of the magpie.
Mr. Zhu's home is on the 13th floor of a building on the easternmost side of Wending Court, and 50 meters from the east balcony is the tower crane where the magpie nests, and the construction site where the tower crane is located is a supporting project under construction in the community.
"As soon as the crane moved, two birds flew out of the nest, and as soon as the crane stopped, they flew back, and every day they had to be frightened several times.
"After eating at noon today, I looked out again, and suddenly a bird flew past my window and stopped there." Mr. Zhu pointed to the tower crane on the moving car, "The bird's nest is built on the cart." ”
Mr. Zhu's daughter Zhu Zhu is in the 6th grade, she usually loves small animals, her father bought her many books introducing animals, and she determined that this bird is a magpie.
To prove her point, she took out a copy of the Bird Atlas and turned out the magpie page to show me. "The bird's tail is black, blue and white, and its white shoulder spots and wing patterns match the magpie features in the book!"
It seems that the magpie couple built the marriage house on the construction site tower and hung it.
After making sure the bird was a magpie, we observed for a while. Whenever the tower crane stopped, the magpie would fly back to the nest, and when the tower crane moved, it would fly to other buildings next to it, but it did not leave very far, looking like it was guarding the nest. The other magpie never appeared. Zhu Zhu felt that the other one might go foraging, and they should have baby birds in their nests.
In order to determine whether there were birds or eggs in the nest, Mr. Zhu took me up to the roof on the 24th floor.
From this point of view we found that the bird's nest was roofed, and the only entrance and exit faced the east, and we could not see where we were.
Half an hour later, another magpie also returned, only to see it fly to the nest, its head facing inward, its tail exposed, arching one arch at a time. Zhu Zhu said that this is very similar to the picture she saw in the documentary of birds feeding their young birds, presumably with food such as bugs in their mouths. "I don't know if the tower crane moving around and the noise in the construction site will affect the birds?" Zhu Zhu was very uneasy about the safety of the baby magpie.
For the fact that there is a bird's nest on the tower crane, Mr. Zhou, who is responsible for the site management of the construction site, has long known.
He said there were three such tower cranes at the site, two of which found magpie nests. We photographed tower crane No. 1, the nest is built on a trolley, and there is also a bird's nest on the top of the cab of tower crane No. 3 on the southernmost side.
"These two birds are very bold, and at the end of last year we saw them holding branches in their mouths, and then we found out that they had nested on the tower crane." Mr. Zhou said that he also saw this kind of thing for the first time, at present, the two sides of the human and bird do not affect each other, they do not intend to drive the birds away, and the magpie symbolizes auspiciousness, and the construction site also wants to take advantage of this to please the head.
However, Mr. Zhou also admitted: "If the bird's nest is found to have an impact on the construction, we can only find a way to move the bird's nest to a safe place." ”
It is understood that magpies usually nest in November-December of each year for 20-30 days. After the nest is built, the eggs are laid, 5-8 eggs per clutch, sometimes as many as 11, 1 egg per day, mostly in the early morning. After the eggs are laid, the female begins to incubate the eggs for 17±1 day. Chicks can leave the nest about 30 days after birth.
