Ученые впервые засняли охоту белого медведя на оленя


Охоту белого медведя на оленя впервые смогли заснять польские ученые из Гданьского университета, находясь на польской полярной станции Хорнсунн на норвежском архипелаге Шпицберген. Свои наблюдения они описали в статье в журнале Polar Biology. Чаще всего белые медведи охотятся на тюленей — подкожным жиром даже одной нерпы медведь может питаться более 10 дней. Однако для охоты приходится уходить по льду далеко от берега, а из-за изменений климата лед тает уже в начале года, и медведям приходится проводить все больше времени на суше. Это вынуждает их искать альтернативные источники пищи — от грызунов и птичьих яиц до мусора на свалках. Существует более десятка сообщений о том, что белые медведи охотились и на оленей — но этому не было документальных свидетельств, кроме того, данные не позволяли определить, насколько успешной может быть подобная охота. Новые наблюдения дали возможность однозначно подтвердить как факт охоты, так и то, что медведи отлично справляются с преследованием и убийством оленей. Исследователи увидели, как белая медведица двигалась к берегу, нюхая воздух. Вскоре она скрылась из виду в тундре, но через несколько секунд снова показалась и бросилась галопом к нескольким оленям. Загнав одного из них в море, в 25 метрах от берега медведица догнала его, вонзила когти ему в спину и перегрызла шею. Повару исследовательской станции удалось заснять происходящее на видео. Так в распоряжении ученых оказались первые документальные свидетельства охоты белых медведей на оленей. Северные олени хорошо плавают, и исследователи считали, что медведю сложно угнаться за ними в воде. Однако на практике это оказалось вполне посильной задачей — после забега по берегу олень, оказавшийся на мелководье с каменистым неровным дном, не смог сопротивляться. Вытащив тушу на берег, медведица съела больше половины за один присест. Обитающие на Шпицбергене олени эволюционировали, практически не имея угрозы от хищников, что сделало их удобной добычей, считают исследователи. Исследователи допускают, что медведи могут регулярно расширять свой рацион за счет оленины, особенно в теплое время года, когда других источников пищи мало. https://www.gazeta.ru/science/news/2021/10/24/n_16742149.shtml

Bergara B-14

When this rifle made a splash in America, gun-counter savants were wont to call it “the rifle the Remington 700 should have been.” Blasphemous though that may be to Remington disciples, the fact is the B-14 is an exceptional rifle and has garnered several national awards. Patterned much like the M700, it has a better extractor and bolt release. Manufactured in Bergara, Spain, the B-14 has quickly garnered a reputation for superb accuracy, thanks to the unrelenting quality of Bergara barrels. This reputation is supported by a sub-MOA accuracy guarantee. Versions range from true mountain rifles to heavy, configurable PRS competition guns. There’s even a B-14 R rimfire PRS-type training rifle. The $865 B-14 Ridge model shown here won the NRA Golden Bullseye Best Rifle award in 2018. It has a threaded muzzle, a composite stock with soft-touch finish, and integral epoxy-pillar bedding. It’s an excellent all-around hunting rifle that won’t let you down..

Ruger Mini-14

The Mini-14 has been around since 1973 and was developed with the help of James Sullivan of AR-15 fame. The Mini-14 is a scaled-down version of the M-1 Garand action and feeds from a detachable box magazine. These rifles are lightweight at just over six pounds, compact, handy and reliable. More recent examples are more accurate than their predecessors and offer additional features such as scope mounts. The Mini-14 has seen worldwide use by security forces and remains one of my favorite truck guns here at home..

Henry Rimfire Lever Action

It can be a challenge to find products made entirely in the U.S. these days but Henry prides itself in that fact. Among its wide variety of lever-action rifles, the rimfire models stand out. These are guns for the entire family that can be used to teach safe and responsible use as well as put meat on the table. Over 1 million Henry .22s have been sold, which is a testament to their quality and reputation. Lever-action Henrys feed from a tubular magazine and are built with traditional walnut and blued steel. Light, handy and capable, this is a rifle that should probably be in everyone’s collection.

Remington Model Seven

When I worked behind a gun counter, probably I sold more Model Sevens than all of my colleagues combined. The Model Seven is essentially a shortened 700 action that maintains virtually all of its virtues. These little rifles prove that you don’t need a magnum-length barrel to have an effective hunting rifle. Compact, relatively light and portable, these rifles are just the ticket for hunting from tree stands, in timber or in thick brush. Though Model Sevens were chambered in everything from the 17 Remington to the 300 SAUM over the years, examples in .260, 6.5 Creedmoor and 7mm-08 are my personal favorites, particularly for whitetails..

Blaser R93

This is an unconventional design that could only come from Germany. The Blaser’s straight-pull bolt action is a marvel of Teutonic engineering, designed for extremely rapid shooting on driven game. The beauty of this rifle, though, is its versatility. Simply by swapping a few components, the R93 can be chambered for any cartridge ranging from .22 LR to .500 Jeffrey. A small take-down case can house the rifle along with an extra barrel or two, creating an incredibly versatile and convenient package for the international hunter. The R93 was replaced with the newer R8 a few years back, but remains a favorite for many.
