For the first half, I read this book at normal speed and then just exactly in the middle I started to scan and speed read. I read certain behavioral sections entirely. Other physiological neuron path and brain form network, I did not read the entire text, just studied the graphics. If you are looking for a book about Crows as pets, Crows' owners long term experiences and other Crow /human interaction first person accounts as witness? You will find far, far more of the dense brain function and anatomy form for Corvid group birds instead.
This is not a book that the normal bird observer will seek out for pleasant tale reading. And I have mixed feelings upon some of the summations, as well. Because as good as this author seems to be within description of differences in brain forms and their functions (not only in the Corvid group but to difference to mammalian brains)and in prose form to the observations of others? Well, he still doesn't seem to have the placements of this group within other Ava groups (and there are thousands). And what Biology or specific credentials for this highly scientific information does he have personally in practice? He's seems more like an accomplished transform technical writer for informational detail than a scientist in that wider or specific field. Particularly not for any sense of inclusions within the broader field of vertebrate forms, certainly.
That may be harsh. But I wanted far more in the quality and specific projections of "bird think" and far less in the physical descriptions and functions of the neuron circuits in Crow brains. Looking at them and understanding the loops? That's not why most people are interested in Crow actions. Or Crow ability to social life memory for every nuance of "tricking" or caching.
It was well worth the read, and I did learn some pertinent facts that I never knew before reading this. Because I have loved birds, had birds as pets (one cockatiel lived to 36 years) and see myriads of types at the lake nearby in MI- I have been reading continually upon Bird study for over 30 years.
So teaching me that Crows do not have cross brain spans, can actually hold half 1/2 their brain completely asleep and 1/2 awake while flying quite well, and other such minutia- that was the best part of this read for me.
Crows are aggressive as are the majority of other birds in this group. So I wanted to know how the pet or long term backyard relationship for mood difficulty or possible troubled interchange played out. And because the tales didn't tend to delve into that territory of reality physical contact much at all? That was the most disappointing aspect for me while reading. Did Dickens cage it? Most practical applications for these intersects are never detailed. You can gentle tame a parrot group member, or Cockatoos, or my beloved Nymphicus Hollandicus (now a completely separate genus all of its own), the cockatiel- but Crows are wild in a much more non-domestic sense by their very natures and IMHO also, size and strength.
It's an interesting book. But not what you may guess it covers by the title. Anatomy lessons prevail.
Ironically, we see huge flocks of starlings, dozens of different song birds, sparrows and finches galore, geese, ducks, and now many other water bird species too by us, but not many crows. And never in multitudes. And hawks, usually Red Tail, everywhere. So it was SO strange than coming home just today I saw a huge crow finishing off a rabbit road kill and never moving more than 4 feet away as successive cars passed it by. It looked like it was grinning. That beak is quite a tool.
