You know what this book reminds me of? Recipe blogs. You go to the blog because you want to make a cake, but first the blogger must entertain you with pages and pages of quotes about the history of baking, quotes from their Mee-maw, unnecessarily long descriptions that you didn't ask for, and bland pictures that don't even properly show what they're making because the picture of this or that ingredient was more aesthetically pleasing.
Each bird entry stretches for pages. Normally I'd consider that a good thing but it's just because the author/editor couldn't cut unnecessary words or substitute in explanatory images. Birding history is scattered throughout. There are zero maps. If you want to know if this sparrow is likely to show up in your area, you need to read paragraphs worth of the author describing the range. Listen, knowing to look in conifers is useful. Including a detailed write up isn't a bad idea. Making me scan TWO pages worth of writing to see if that sparrow ever makes it to the Eastern hemisphere is cruel. JUST PUT MAPS IN YOUR BIRD BOOKS.
There are plentiful pictures but their usefulness varies. Consider the chipping sparrow - three pictures, all of them of the bird facing to the right. What's it look like from the front/back/at an angle? Dunno. In addition there are no quick and dirty descriptions - you have to be willing to sit with this book and basically read it front to back and frankly I found it neither interesting or pretty enough for that.
Let's continue with the chipping sparrow. Nearly two pages of geography descriptions. (No maps, remember!) Approximately one page of written description of the bird. One page of reminiscing about things like William Bertram's description of the bird. It seems like all the birds get big write ups but it's just unnecessary wordiness. That's this book in a nutshell. It even includes an extinct sparrow, with four dead pictures of dead birds. If it wanted to be a history book, that's fine, but making it both just created a too large book that does a poor job as both an identification guide and a history book.
If you want an identification guide: this ain't it. If you want a rather large, heavy hardback that provides some VERY THOROUGH history on ornithology, but in a scattershot way where you have to read through each sparrow to collect all the history, quite of bit of which is rather randomly chosen, this is the book for you. Honestly, I didn't enjoy it, it's too big to be either a guide book or a light read on history, I won't use it, the image quality is okay, and it arrived with a rumpled and torn dust cover. I'm doing something I basically never do: I'm returning it.
