Белка обыкновенная (Sciurus vulgaris) - необычайно юркий зверек, для которого характерны длинный пушистый хвост, разделенный посередине пробором и уши с "кисточками". Длинна тела около 25 см, длина хвоста - 20 см, вес взрослого животного - около 250 гр. Подошвы ног голые. Мех обыкновенной белки в основном бурых тонов и может варьироваться от глубокого черно-бурого до красно-бурого. Не зависимо от общего окраса, брюхо всегда светлое. Цвет меха зависит от среды обитания. Так, в лиственных лесах и в городских парках, где мало хвойных деревьев, господствует красно-бурый вид, а в хвойных лесах встречаются преимущественно черные или темно-бурые животные. Вероятно, цвет белки зависит и от микроклимата, так как красные и красно-бурые белки встречаются преимущественно в теплых и сухих местах обитания, а черно-бурые - в холодных и влажных. Порой различные цветовые морфы встречаются на одном и том же месте.
Обыкновенная белка распространена по всей Европе и далее через Кавказ и Урал, по всей южной Сибири до Алтая и Восточной Азии. Живут белки в лесах всех видов от низменности до гор.
Белка хорошо лазает по деревьям. Она так же быстро взбирается вверх на дерево, как и спускается внизголовой. Белка хорошо и прицельно прыгает.Небольшая масса позволяет ей взбираться на верхнюю часть кроны и на концы веток деревьев. При этом длинный пушистый хвост служит белке своеобразным балансиром. А во время прыжка он служит ей рулем.
Белка ведет дневной образ жизни. Гнезда (гайно) шарообразной формы она строит из веток и листвы в дуплах или в кронах деревьев. С наступлением ночи белка прячется в свое гнездо и спит там, пока темно, но, если это необходимо, может ориентироваться и в темноте. У нее хорошо развиты зрение, обоняние и слух. Зимой в спячку белка не впадает, но в особо неблагоприятную погоду может некоторое время не вылезать из гнезда и находиться в состоянии дремы. Благодаря пониженной активности уменьшается потребность в пище.
Темно-бурые белки хвойных лесов особенно бурно реагируют на урожай еловых шишек. Настоящие урожайные годы редки, но тогда белки рождают большое количество детенышей и плотность популяции возрастает многократно. Семена хвойных чрезвычайно питательны, и их легко добыть. С шишками белка управляется очень ловко. За день зверек обрабатывает 10-15 еловых шишек или более 100 сосновых. Белки не очень разборчивы в пище и перемалывают все, что попадет на их крепкие зубы. Меню белки достаточно богато: орехи, буковые орешки, семена ели, сосны, пихты, желуди и семена других растений, а также ягоды, плоды, грибы и мелких животных. Они разоряют птичьи гнезда, поедая птенцов и яйца. Грызут молодые побеги деревьев. В лесах юго-восточной Сибири белка делает запасы грибов, притом довольно забавным способом. Она не прячет грибы (как поступает с орешками и желудями), а натыкает их на иглы или на мелкие сучья в лиственных лечах, где они высыхают.
Наивысшую активность белка проявляет в период спаривания, когда самцы устраивают настоящие гонки за самками в кронах деревьев. Все остальное время белки живут поодиночке. Основное время размножения приходится на весну и начало лета. В год обычно бывает 2 помета. Беременность длится 28 дней; в помете 4-5, максимум 7 детенышей, которые рождаются голыми и слепыми. Поскольку беременные самки часто строят запасное гнездо, то при разрушении первого гнезда они могут быстро перетащить детенышей в новое. Вход в гнездо устраивается обычно внизу сбоку, так как белке удобнее забираться в него снизу вверх. Этим оно отличается от птичьих гнезд.

Finals past season, Arsenal’s performance [url=http://www.kdshoes.us.com]kevin durant shoes[/url] is just not very ideal, although the data well, but the efficiency is just not high, and his returning pass error, defensive irvine was produced key 3 points have become a "black spots" minute, apparently, in hope that in this to prove himself.
Simply no, after the opening, the three points within the database and didn’t reach two shots, on the actual contrary, the knight three points would hit several over there. Garage or target defense, he para as well as lebron, Irwin, JR., has been people already, also get successful prevention.
In moving, did well in the actual Treasury, the ball with a teammate are fed correctly, but Mr Chu in many opportunity attack. 04 seconds left in the first quarter, garage dribble towards frontcourt, rhythm, but they are confident the take a few steps away from the three-point line and it’s really necessary to make [url=http://www.curry-shoes.com]curry shoes[/url] techniques, the ball! This is also the warriors in the 1st 3-pointer today. Soon, the Treasury and using second chances on the right side of the camp again in a 3 items!
It is worth mentioning which the opening, the garage right arm was wearing a black gear, it can be because his right elbow from the game before the old injury has a relapse, however, with the action, he has to take off protective devices. Gear, seems like, has affected the cope with, before he took off as i feel much better.
In against lebron James, the defense does very well in their Arsenal, but after he was lebron was a knocked out, the referee features [url=http://www.stephencurryshoes.us]stephen curry shoes[/url] blown the garage stopping foul, garage on the floor is various, make action towards referee said lebron knee.

Garage into seven three-pointers inside the game, this also let his / her playoff three-pointers hit number up to 261, match the Robert horry, ninth three points in playoff historical past list. Distance comes 8th Chauncey billups, he also only six three points.

The first several games, garage is averaging twenty-seven. 3 points and some. 7 rebounds, 6 helps, shooting 40. 3% in addition to 35. 3% from several, compared with the standard season shooting stage, a specific degree of decline, though the game, garage completely ridiculous.

Garage within the [url=http://www.stephencurryshoes.us]stephen curry shoes[/url] second dribbling is toward the switch on the left side on the body without any slowdown, their footsteps choiceness and rapid, soon arrived at the position you would like to go. Unlike most pitcher like the center of gravity down, then struggled to jump to finish, the garage action a lot more concise. Don’t waste any hard work, just jump off the ground, slightly triggered his firing action instantly. "He is not only just about the most pure great scorer, he even gave shot two words to produce the definition, the entire shooting art played some sort of revolutionary role. "The bobcats go scout work Adam : Mr Libby said Treasury.
Counter-top frames in 6 minutes and 31 seconds, garage from his chest slightly next point position held up the ball, the index finger along with middle finger instinct to get gaps in the silicone ball center. His arm gently lifted back, quit his palm the soccer ball, but still control involving his fingers. His right arm into all the joints is close in order to 90 degree Angle, through the shoulder to the knee, from the elbow towards wrist, from wrist to talk about, as if a eating place waiter in carrying any tray.
Glen Davis clippers, 289 - pound in-front, [url=http://www.curry-shoes.com]curry shoes[/url] need to speed up their action inside Treasury, since the childhood to lay a good foundation for complete to garage in different state, the right arm and shooting is able to keep perfect posture and power. And in addition to master hand movements, garage includes a precise shot needed an additional factor: enough deep muscles memory. Shooting touch just isn’t a proper adjective, a single player, able to throw an excellent shooting there is although one secret to all - every single day, year after year train, until a set regarding complex dynamic chain implanted into muscle tissue. Garage never resist for example monks meditate boring exercise, it also helped any time he graduated from school, eventually grow into another leading little-known Davidson college or university NCAA elite last seven.
"Game changing, there is no time to [url=http://www.kdshoes.us.com]kd shoes[/url] you consider your own shooting action is correct, " curry stated, "you can only depend on their daily at working out ground building muscle ram, hit and believe that any of us can. We’re so plenty of practice in training, so as to the game, you can count on instinct to react. But if it is not in the right way, the game will really feel very strange. ".

As being a core point guard, garage as well as other three split the difference is which he is the team recruit and organizer. In other words, he can’t resemble novak on the perimeter around awaiting [url=http://www.kdshoes.us.com]kd shoes[/url] someone else to supply him the ball. We take novak with a comparison, everything also - reference counted for individuals each a 3-pointer aids objects, and to period, after statistics, novak found in 2010 hit 3-pointers, 149, 146 is often a teammate’s pass and struck; Three-point shots hit the other more this season Ryan - Anderson is no exception, he hit [url=http://www.curry-shoes.com]curry shoes[/url] in 213, has 206 relies upon your friend’s passing.
The garage He all the 3-pointer this season, you will discover 105 of 3 is not sending (272), quite simply, is to create options, nasty sto vote. This trick from the team’s star, such while flow of harden, vladimir radmanovic, kobe Bryant, John, but often because somebody errs, physical strength ingestion, to the number of times few, and the hit ratio isn’t high. But obviously is an exception in the Treasury, his three-point shot 105 times just isn’t assists quantity highest within alliance,[url=http://www.stephencurryshoes.us]stephen curry shoes[/url] even better than lebron James thrown directly into more all 3-pointers, along with the shooting is in a new league all five such not assists free-throw shooting players from the fifth (41. 8%), each quality and quantity. Considered together, the three points to help thrown into space seriously isn’t an easy thing, must have the forty percent three-point shots need to create his own photographs, this how tired! The most precious is, no make a difference when and where, and steps to make moves, garage has an increased percentage. It is no wonder that the manager of the players when Bob myers not long ago told the Associated Press said: "as long seeing that it’s garage, to receive the ball is reasonable. ".
