Amy,
Funny you should ask this question because I just began reading 'The Singing Life of Birds' by Donald Kroodsma. He records bird songs and then transfers them to specrtograms to see what the song looks like. For instance, he says that within the Point Reyes area there are six distinct dialects of White-crowned Sparrows there and then proceeds to show you the spectrograms and how they look different. Pretty interesting so far but I've only read the first chapter so I'm not sure how the rest of the book will be.

I'm always on the lookout for puzzles, and here's one I would love to
solve. How can I found out the frequency ranges of bird
sounds?

Why would I want to know this? If I knew the
frequency of a specific bird's song/call, I believe that information
combined with other tools like mnemonics would help me identify more
accurately what species I think I'm hearing deep in the grass, woods or
high over my head in overcast skies.

Not only that, with more
than a half-century of use on my ears, I want to know what I could be
missing.
