Dove age judgment

1, according to the replacement of pigeon feathers to identify:
The main wing feather is used to identify the age of the youngster. There are 10 main wing feathers of the pigeons. At the age of 2 months, the first one will be replaced. Then one root will be replaced in 13 to 16 days. When the last one is changed, the pigeons will be about 6 months old. It is already mature. Pairing production can begin. The pigeons have 12 main wing feathers, mainly identifying the age of the old birds. Auxiliary wing feathers are sequentially replaced from the inside out, and the replaced feathers appear dark and clean.

2, according to the shape of the doves and mouth knots to identify:

The older you are, the more blunt and smooth the tip of your gill. The end of the pigeon's cockroach is pointed, soft and slender; the cockroach's cockroach's cockroach is thicker and stiffer; the adult cockroach's cockroach is thicker and shorter, and its end is hard and slippery. Due to feeding the pigeons, the adult pigeons show lice in the corners of the mouth and become knotted. The older you are, the more you feed your baby, and the bigger the lice of your mouth are, the more jagged on both sides of the corner of your mouth than 5 years old.

3, according to the size and color of pigeon nose tumor to identify:

The pigeon's nose was red, but the pigeon was light red and shiny. The nose tumors of the pigeons more than two years old had a thin pinkish white, and the nose tumors of the pigeons more than four or five years old became rougher and more than 10 years old. The pigeons appear to be dry and rough, and the pigeons' noses increase slightly with age.

4, depending on the pigeon's eyes flexible hair and the number of eye skin wrinkles to identify:

Youngsters' eyes are smarter, youngsters and young adult birds have bright eyes, and the eye blinks faster. Older birds have slow eyes and poor flexibility. In addition, the skin circles of the young pigeons have very fine wrinkles. With the increase of the age of the pigeons, the wrinkles of the bare skin become thicker and thicker.

5, according to the size of the capsule of the pigeon cavity, with or without identification:

The bursa of the pigeon is located above the cloaca. The cavities of the youngster's cavities are relatively large, and they become smaller when they are old birds. After a few years, the bursa on the cavity becomes very small, or only a trace remains.

6, according to the pigeon's foot ring to identify:

Pigeons and ornamental pigeons often have their legs marked only with the numbers. This can be determined based on the time of registration at the time of placing the foot ring; the pigeon's foot ring is often marked on the date of birth, and thus the age can be known.

7, according to the color of the pigeon's feet and scale thickness to identify:

The color of the youngster's feet is bright red, the scales are not obvious, the scales are soft and flat, the toenails are soft and pointed, and the mats are soft and slippery. More than two years, the color of the pigeon's feet is dark red, the scales are fine and clear, and the scales and toenails are slightly hard and curved. Pigeons more than 5 years old are purple in color, with large scales and coarse scales. The scales are prominent and rough. White hair is attached to small scales. The nails are hard and curved, and the pads are thick and thick.

Long Range LiDAR Radar

Long distance LiDAR sensor IT03M series are particularly easy to communication thanks to their fixed connector, which can be plugged it up and off by yourself. Voltage is wider from 3.3v before to 3.6v. Low power consumption feature makes it beceome a very competitive, high performance-price ratio, long range Laser Distance Sensor.

Highlights:

> Measurement frequency: 100 Hz (Max 200 Hz)
> High temperatures: -10~+50℃
> UART output
> Connector design: easy to use
