Distinctively ages from pigeon doves and beaks. The older the dove, the more blunt the scorpion is, the smoother it is. The adult pigeons show a knotted lice in the mouth. The more you feed your baby, the bigger the clams are, and the more than 5 years the birds are jagged.
Age discrimination from nasal tumors. The noses of the pigeons are red, while the pigeons are light and shiny. The nose of the pigeons for more than two years is white and rough, and the pigeons that are more than 10 years old are rough and dry. The pigeons' noses are also slightly older with age. Variety.
Look at the age of the feathers. The pigeons had a total of 10 main wing feathers. At the age of 2 months, they began to replace the first one, replacing one main wing feather approximately every other half month. After completely replacing the pigeons for about 6 months, the pairing production began. There are 12 main wing feathers of the pigeons. Each year, one feather is replaced from the inside. The feathers after replacement are dark and clean.
See the size of the capsule on the cavity to determine the age. The bursae of youngsters are relatively large, and they become smaller when they are old birds. With age, there is only a trace of bursa.
With low-power, miniature size, the serial communication department range sensor with mm accuracy can measure up to 20m, 40m, 60m, 100m, 150m, 200m.
