And from all this group the diamond dove occurs most frequently. Head, neck and underparts of its body is ashy-grey; back, wings and tail brownish; wings small white spots; a ring round the eyes wide, bright orange in females and young males it is much narrower and paler; the bill is gray at the base, the tip blackish-brown. Length of the bird – 19-20, tail 10-11 cm
Widespread in Australia, inhabiting forests and thickets of bushes, growing near the water. They love to bask in the sun, growing near the water. They love to bask in the sun, flat on the ground. Most of the time on the ground in search of food, but resting on the branches of trees. Runs along the ground quickly, deftly shuffling your feet. They are kept in pairs or small flocks. The flight is fast and is similar to flight of the nuthatch.
When the nesting period, often heard the voice of the male, repeating the sound: “crow”, “crow”. With tail fanned before the female. 3-5 days after start of construction the nest is ready, and after a few days there are eggs on which the female sits very closely and get away with them only in the case of obvious danger. The incubation period lasts about 2 weeks, the Chicks leave the nest at the age of 13-15 days for the first time we spend the night in the nest or at the nearest branch of nedalekom parents.
The diamond dove belongs to the best room for the birds. She is graceful, beautiful, neshumova, always calm, not afraid of humans, gets along well with songbirds. For the first time this dove was able to breed in 1875 and since then it is successfully kept in cages. Continue reading
It is believed that cats, dogs, parrots, fish and ferrets – Pets. The rest we usually accustomed to seeing in the gear or the BBC in the zoo. Meanwhile, foxes, raccoons, and even alligators can be tamed and kept in a standard city apartment.
In nature foxes are timid and cautious, if you meet a Fox in a forest, she will run away from you. But if from birth to raise a Fox at home, she will become tame and even will wear you Slippers.
One of the first foxes to adapt to home life was scientist Dmitri Belyaev in 1959. The scientist then working at the Novosibirsk Institute of Cytology and genetics and conducted an experiment on foxes special coloring is silver – black. He tried to bring an obedient individuals, who would be able to live peacefully with man. The experiments were conducted until then, until a breed that is most adapted to life among humans.
Such an obedient Fox differs from “forest”. She has a roundish face, blue eyes, and the color can vary from pure white to dark red. For comfortable living foxes at home she needs a little daily to comb hair (especially foxes) and walk in the fresh air. To teach a Fox to a leash fairly easily. Siberian breed standard dog collar for dogs, and the Fennec Fox (Fox is native to North Africa, listed in the Red book) it is better to buy a leash for walking cats.Foxes do not like being alone, easily get along with other animals and loyal to his master. But never hurt a Fox – or it is forever. It is not revenge, but self-contained. Continue reading
Rotifers (Rotatoria) — the smallest of multicellular animals, together with the ciliates are part of the so-called “living dust”. Their sizes vary from 0.04 to 2 mm. Its name rotifers received for the presence of a rotary machine consisting of two beaters of the cilia on the anterior part of the body. The movement of the cilia creates a whirlpool through which small food organisms are sent to the mouth. Simultaneously with this apparatus, many forms of rotifers is swimming. Rotifers are less mobile than the infusoria, which makes them more desirable starter feed for larvae of the vast majority of fish. Small size, high proliferation rate, as well as the possibility of sustaining a culture in pure form do rotifers are very easy targets for rearing of juvenile fishes. The most commonly cultivated of the saltwater rotifer Brachionus plicatilis, because its the easiest to maintain in pure culture. This small rotifers — 100— 300 microns. The average weight of 1 million rotifers — 1.5 g Eat phytoplankton, bacteria, yeast. Males live for 2-3 days, females up to 2 weeks. Sexually Mature in 1-1. 5 days. Actionsee females reproduce by parthenogenesis, laying (2N) eggs. Misticheskie — give eggs, of which face males (N), or participate in pairing, putting resting (2N) eggs. The eggs are heavier than water. Rotifers coltivirus capacity 3-100 l, reaching a density of 100-300 individuals per 1 ml. Desirable very weak purge and side lighting. Culture enters stationary strength for 5-7 days.
The technology is extremely simple: take a piece of yeast the size of a large pea and fingers rubbed at the Bank of rotifers. Once the water clears up (for me it’s usually 2-3 day) add the next portion. I feed her fresh yeast or dry. Rotifer does not like strong aeration, if we use a very weak blow. I don’t use at all, then all culture is concentrated in the upper layer. The system itself is organized in the following way: on the windowsill is a three-liter Continue reading
