How to tell if myna is male or female? Can myna have children without mating? How old can myna live?
1. How to tell if myna is male or female? Answer: It's a male with white feathers under one wing. It is a male animal with feet. The hair on his head sometimes stands on end ... 2. Can myna have children without mating? Answer: Of course not! 3. How old can myna live? Answer: I heard from the bird buyer that myna can only live for two years. I think he is a liar. Who can tell me how many years myna can live? Moreover, my myna's hair loss is ... it is known that myna is not an ordinary bird ~ ~ its life span is very long ~ as long as it is kept well 18 years, it will certainly be no problem ... The average life span of birds is 50-60 years old. According to the British "Independent" reported on the 3rd, according to the latest international research, birds actually live longer and fly farther than scientists thought. This study found that the life span of birds has far exceeded the previously recorded age, and some birds have metal rings on their legs for more than 30 years, which completely changed scientists' original views on the average life span of several birds. The metal ring on the goose leg was put on 27 years ago. Researchers from BTO have been communicating with their peers and bird observers all over the world about the details of bird activities, and have compiled a latest report on the living habits of various birds. All these birds are put on metal rings to help track their activities. Researchers found a black goose in Solvey Bay near dumfries. The metal ring on its leg was put on 27 years ago, which makes it at least two and a half years longer than the previous record. Scientists estimate that this goose has flown at least 6.5438+0.5 million miles, because it migrates between Solvi Bay and its breeding ground in Svalbard (between northern Norway and the North Pole) every spring and autumn. Scientists also found that the metal ring on the leg of the crested diving duck (Zefu) photographed in Salava, Russia, was put on 22 years ago in Lincolnshire, England, when it was only a few months old, and Lincolnshire was 2,200 miles away from Salava. The longest-lived black duck recorded before was 17, 9 months and 24 days. These new records are the result of the joint efforts of international bird researchers and help people understand their activities and living habits. In 2004, volunteers from the British Bird Trust put "identification" metal rings on 882,000 adult birds, breaking the record of 859,000 birds set by 1995. The farthest bird is Haiyan, whose seasonal migration flight distance is nearly 6000 miles. Scientists have discovered long-lived birds many times before, such as a 36-year-old oyster snipe in Norfolk 1968 and a knife-billed auk in Gwyneth 1962. In addition to recording the life span of these birds, scientists also investigate which birds fly farthest. Among them, one of the birds with the farthest flight distance is a petrel, which was put into the ring in Ilsand, shetland islands in July 1982 and was captured near the Namibian coast in February 2004, with a seasonal migration flight distance of nearly 6,000 miles. In addition, they estimate that an ordinary tern has flown 665,438+000 miles. This tern was placed on the metal ring of Saunders on Mount Tismouth in 2003 and was found in Lambert Bay, South Africa in June 2004. Scientists initially thought that birds in smaller woodlands lived relatively short lives, but a discovery changed their view. Scientists found a dead woodland bird in Novgorod, Russia. It was worn on a metal ring in Suffolk, England 17 years ago, which was 16 months longer than the previous record. Jacques Clark, head of the bird collar research project of the British Bird Trust, said: "It is always exciting to write a bird collar research report, but it is rare to break so many records in one year. Unlike humans, birds experience short middle age and old age. When they mature, they will be healthy for most of the rest of their lives. " Ornithologist: Some birds live for a long time. We can't imagine Clark saying that once the physical condition of birds doesn't reach the standard level, their survival time will not be long, and they gradually lose the speed characteristics necessary to avoid predators. Long-distance migration slowly consumes their energy, and cold winter will bring serious consequences. Clark said: "Some birds live longer than we can imagine. We announce that a 50-year-old Marne seagull and a 42-year-old knife-billed auk have returned to their habitat in Wales to nest. In addition, the oyster snipe, one of the largest birds involved, is another typical example. The longest span from collar to discovery is 36 years, and one of the oyster snipes may be 40 years old now. " The research on bird collars has enabled scientists to have a deep understanding of the changes in the bird migration model, although on average, less than one of the 50 caged birds was finally reported to the British Bird Trust. Clark said: "I would like to express my heartfelt thanks to the thousands of lovers who report ringed birds to the British Bird Trust every year."
