Grizzly Bear Yellowstone
Grizzly Bear in Yellowstone National Park Ursus arctos horribilis
Reaching weights of about 400- 1500 lbs, the grizzly bear is mainly nocturnal and in preparation for winter will put on hundreds of pound of fat before going into hibernation. Their coloring ranges from blond to deep brown or black. The grizzly has a large hump over the shoulders which is a muscle mass used to power the forelimbs in digging. The head is large and round with a concave facial profile. In spite of their massive size this bear runs at speeds of up to 35 mph. Being omnivores, they feed on a variety of plants and berries including roots or sprouts and fungi as well as fish, insects and small mammals. Normally a solitary animal, the grizzly congregates alongside streams and rivers during the salmon spawn. Every other year females produce 1-4 young which are small and weigh only about 1 pound.

Medvěd hnědýMedvěd hnědý je medvědovitá šelma, všežravec a jediný zástupce své čeledi, který se vyskytoval a vzácně stále vyskytuje na území Česka. Z celosvětového hlediska má druh holarktický areál rozšíření, ve kterém obývá především zalesněná stanoviště. Je to jeden z největších suchozemských masožravců, kterému konkuruje pouze jeho nejbližší příbuzný, medvěd lední, jehož míry jsou napříč populacemi mnohem konstantnější a který je v průměru o něco větší. Medvěd hnědý je pohlavně dimorfní. Dospělý samec bývá v průměru až o 30 % větší než samice. Obecně měří 100–220 cm, z toho ocas 5–20 cm, v kohoutku 90–150 cm a váží 100–350 kg. Do největších rozměrů rostou především americké a severoasijské poddruhy medvěda hnědého, obzvláště pak medvěd kodiak, medvěd grizzly nebo medvěd kamčatský. Podle některých zdrojů mohou dosáhnout délky až tří metrů a hmotnosti až jedné tuny. .. pokračovat ve čtení
