natural territories of Moscow, for example in the Park “Kuzminki-Lublin”, started frog concerts — so experts call male singing frogs, who thus attract females for spawning caviar. They sing in a variety of Metropolitan bodies of water — ponds, rivers, flooded marshes, ditches.
According to experts Mospeada, green frogs, with sides of the head bubble resonators on the natural areas inhabited by lake frogs wintering in the water, and pond, wintering on land. Another view of the green frog — edible frog is hybrid of the above types. Lake and pond frogs in recent years, experts have seen only in areas outside Moscow.
In Moscow it is possible to see representatives of the two types of red brown frogs — grass and moor. They are smaller green, often brown in color, do not have external resonators, but also unable to shout loudly, using a small amplifier under the skin of the throat.
Different species of frogs begin to breed at a certain temperature of water, five degrees for moor frogs to 10-12 degrees to brown. This is due to the fact that small puddles and creeks warms faster than large ponds.

Frogs are quite vulnerable creatures, but the males during the breeding season exhibit sufficient activity and sometimes aggression. For example, male common frogs trying to grab any moving object, and the moor frog males guarding the eggs, throw on living and moving inanimate objects.
Experts remind that it is necessary to protect these ancient creatures, vulnerable in the city.
