Flevoland, near Amsterdam, is the biggest land reclamation project ever. This is pushing polar bears, which are particularly adapted to a diet of high-fat blubber and meat, further south out of their hunting zone in search of food, potentially altering their diets and consuming foods they are not well suited for, according to a study published in Global Change Biology. These creatures are actually known as pizzly bears if the father bear is a polar bear, and a grolar if the father is a grizzly; in this case, they cant be sure which it is, but its definitely a rare hybrid regardless.

If two or more once-distinct species completely collapse into a hybrid swarm, thats a net loss, an outcome to be avoided. However, true hybrids have definitely turned up in the wild in recent years. In Alaska, this has led to cross-breeding with native grizzlys and the creation of 'pizzly bears.' Also called a grolar bear or a nanulak, this hybrid species has been known to occur both in.

A rare grolar bear, a grizzly-polar bear hybrid, has been killed in the frigid upper expanses of Canada. Then in the early 1980s the ecology of the island shifted, following an extreme El Nio that brought torrential rain. However, in the 1980s, their progress came to a halt due to economic difficulties and fear that ubros would breed with native wisents, causing genetic pollution. Furthermore, they have long necks like polar bears, but small shoulder humps like grizzlies. Pizzlies and grolar bears are undoubtedly striking curiosities, but how regularly do they show up in the wild?
