Perhaps I should modify my stance on discovery/solving puzzles/ and mystery.
An aside: corvids are quite the puzzle solvers.
Back to that in a minute.
I really like the idea of solving a mystery, which opens to a new mystery.
Bernd Heinrich says something similar in his studies as a naturalist…and ornithologist…that when he goes to solve something with one idea of what is happening then he is absolutely delighted when he is wrong and nature shows him something else that’s happening.
I highly recommend any of his books…including the ones on ravens.
Bernd does a lot of study in the field and while in his Maine cabin a reference to Thoreau or Frost wouldn’t be out of place even if like Parzeval some of Bernd’s methods such as climbing trees for raven eggs at least during one period of his life would be more unorthodox.
Bernd emphasizes the need to interact with nature in order to appreciate it rather than build a fence around it.
He often says after making a discovery about a mystery in nature that is the closest thing (to truth and beauty.)
Or even for a better quicker view introducing Bernd Heinrich is an independent film dvd made by Jan Cannon. “An Uncommon Curiosity at home and in Nature with Bernd Heinrich.”
As for Ravens…they are larger than crows. Some have compared their size to be about equal to a red tail hawk.
Raven’s also have a wedge tail, which crows do not have.
Crows are sleek and shiny black.
Ravens are more ruffled. Even though they are dark black with undertones of purple/blue. Crows have sharp pointed beaks.
Ravens have large beaks sometimes jokingly remembered in comparison to having a “Roman nose.” The Beak is rounded on the top.
Ravens over all tend to be much shaggier than their shiny cousins.
Both Ravens and crows have demonstrated excellent puzzle solving skills. Trained Ravens can learn words just like parrots.
I think Heinrich was one of the first to prove juvenile ravens worked together to find and protect food caches.
Ravens are fascinated by various trinkets it’s proven now and some have even suggested Corvids have “left gifts,” for humans who have fed them.
gifts such as pull tabs and pine cones.
Heinrich after working with Ravens believes there is a “consciousness,” there. I’ll have to find that link.
Their intelligence is considered to be remarkably high…along with simians, dolphins and parrots.
Some of the information is from Bernd Heinrich books and some from other articles and bird guides I’ve read but unfortunately don’t remember the sources now.
So that’s more Raven…trivia
