Another reference question: someone was looking for a particular photograph of ravens she had seen in a National Geographic article about five years ago. According to Geographic's index there was an article about ravens in the right time frame; but when the magazine was fetched up from the basement, none of the pictures looked right. No other articles mentioning ravens (in the index) were listed as published in the right time frame.
So we tried Google Images and Yahoo Images (as of just lately Yahoo's images database is a lot bigger than Google's). Still nothing that worked.
Next we tried the area of the stacks where the bird books are. In the end she checked out Bernd Heinrich's Mind of the Raven: investigations and adventures with wolf-birds--not a glossy picture book, but with photos selected to clearly show raven behaviors.
Readers know Heinrich mainly for his books about his work with ravens, but my personal favorite is his last year's book, Winter World : the Ingenuity of Animal Survival, a riveting description of how a working scientist goes about solving a deep mystery: that teeny tiny creatures--kinglets, bees, the smallest ground squirrels--can survive sub-zero Maine winters.
