About a year ago, I acquired a large stack of relatively recent National Geographics via Freecycle. These bound pages offer a much more orderly reference than miscellaneous scraps. Plus, I learn things.
For example, the reference photo of this Polar Bear comes from an article about Franz Josef Land. I'd heard of Franz Josef Land but was not sure where, exactly it was or that it is part of Russia.
My reference photo for this entry is by Cory Richards and the caption reads, "Polar bears eat mainly ringed seals and bearded seals, captured on sea ice. On land they scrounge seabirds, eggs, even grass. This animal grazed for days below Rubini Rock—then chewed up the remote camera."
