Does anyone know why almost all black bears in Eastern North America are black while Western North America has lots of colour phase bears ?
Just wondering...

Likely due to the higher tolerance of gender and racial fluidity out this way.....
I always believed it was an adaptation based on climate, habitat, water etc.

So due to certain environmental conditions a different colour could be a favourable adaptation for survival. So because of natural selection the coloured phases had a better chance to survive and pass on their "coloured" genes to their offspring. Resulting in greater numbers of coloured bears in that particular environment???
Have I got that right? How about areas where there are equal numbers of black and coloured bears?
Any geneticists out there??
From what I have heard it from numerous sources, precipitation plays a role. Higher precipitation climates have a higher % of black colored bears. It seems to make sense, areas like the coast, back east etc have more black colored bears while places like Arizona, Utah, Interior of BC have more color phases. From my experience hunting them this holds true

Perfect HONEST explanation ! RJ
Just for Men hair dye. Every spring different bears try and hide their natural fur colours by colouring their hair to attract a mate.
