The average period of spring: the amphibians

In early May, fast river shallows spawning chars. Usually in May, spawning roach, going to large schools in shallow grassy areas and in the reeds. A week before the spawning of roach males are covered by a rough rash, which sharply distinguishes them from the smooth, thick and large females. On the head and back them appear like white pimples. Once the eggs postponed, roach goes into the hole and rests there for a few days. At the same time as the roach spawn and minnows. They lay her in several stages with the first ten days of May to the middle of the month. At this time, they're going to rapids, to the small rocky places and noisy splash, leaning out of the water. Pairs on the fine sand spawn small schipovki. These beautiful colored fish - a permanent resident of the river bottom. Crawling on silt and sand, it catches out any edible detail. The aquarium is easy to see how schipovka absorbs mouth sand bottom and releases it with water through the gills, apparently, leaving themselves all that you can profit. Any anxiety causes her hide. It is upside down and in a moment buried in the sand, exposing the tip of his sometimes out of acute stigma. Through him, she draws in water for respiration. Apparently, just lazy male and female eggs carefully buried in the sand, hiding it from the numerous enemies. At this time, you will not hear another loud croaking green frogs, which lay eggs in ponds, lakes and backwaters of rivers much later. They need more heat. From spring until the water is distributed only to a quiet rumble of male grass frogs. In puddles, ditches, ponds and wells appear swollen pile lining and a slippery frog spawn. Average life began rumbling frogs have near Moscow on April 24. Held more crescent, while green frogs will open its season of concerts. Beginning of their croaking almost coincides with the end of the middle part of spring. On a warm spring in late April, but more often in early May, getting out of winter gray toad burrows, and usually soon descends into the same waters warmed. Here, she starts laying eggs. Roe it lies not dense heaps, like a frog, a long slimy cords. In May spawn newts, which at this time it is easy to find a male to a high jagged or scalloped crest that decorates his entire back, from head to tail. Later, after spawning, when the newts are selected on the shore, the crest disappears and with it disappears and the external sharp distinction between the sexes. Emerges from winter shelters in late April-eared turtle. Shortly after waking males start to produce sounds similar to a quiet whistling - a sign of impending mating. It is necessary, however, noted that turtles only accidentally found near Moscow: caught caught here from captivity. Their real home - a warm area.
