I almost never read books twice. "Field Notes from an Unintentional Birder" is an exception, even with a title I found off-putting.
I read it happily, and while reading it again will honestly say it is the best-written bird book I've come across.

The author, Julia Zarankin, tells a great story, and has a great story to tell. The book is as much about her as birds. It more or less begins the moment she realizes that when her newborn nephew is her age she will be 82.
She has a marriage soon to end, a career that no longer fits, and a nagging question: Is this all there is?
She is looking for a hobby. She and her sister meet a birding couple, they talk, the birders non-stoppable about what they have seen and heard. Eventually, the birding woman says, "If you're very very quiet you might hear a bird." Our heroine, however, is bored.
Some months later, talking to her sister, she admits she has not found a hobby that fits.
"What are you looking for?"
"Something that will exercise my patience."
