Book launch imminent!

Book launch imminent!

The Peterson Field Guide to Bird Sounds of Eastern North America will be available in stores on Tuesday, March 7!

Last Thursday I talked about the book with Mark Lynch of WICN – you can hear that interview online. Tomorrow morning (Sunday March 5), I’ll be interviewed live on Ray Brown’s show Talkin’ Birds, which is syndicated all over New England! Listen in at 9:30 AM Eastern.

I will be doing a lot of traveling this year to promote the book! Check my current list of events to see if you can catch me in your area. If you’d like me to speak to your group, just send me an email!

Stay tuned for more news and posts!

  1. I love the book but…not sure the website for bird sounds is up and running? So far I can’t access it with link provided in the book.

  2. Nathan,

    Have had the book pre-ordered for half a year. Just recieved and am enjoying greatly. I am also looking forward to your appearance on the ABA podcast with Nate Swick.

  3. Nathan, very well done!! A fine achievment!! Enjoying my copy!!

  4. Thanks, now I have the sounds. Fantastic. And I enjoyed your talk with Mark Lynch at WICN very much – shared it with my local birding group. Well done!

  5. Love the book, but I was wondering how you figure out what the frequency is for a trill that spans a range? Like the trill of a Grasshopper Sparrow for example.

  6. Hi Derek,

    Well, that’s a complicated question. Depends on whether you’re talking about frequency (how many vibrations per second are in the sound wave) or pitch (how high the trill sounds to the human ear). In the case of frequency, it makes sense to talk about mininum frequency, maximum frequency, and median frequency, all of which you can derive by looking at the frequency scale on the spectrogram. In the case of pitch, it’s complicated. For something like a Grasshopper Sparrow buzz, in which all the elements of the trill are chip- or ticklike, it’s impossible to assign one pitch to the sound. That is, it’s impossible to say which note on the piano the bird is singing, because the sound isn’t musical. (In fact, a good definition of an unmusical sound is one that can’t easily be assigned a pitch.) But you can tell that the buzz will be very high, because it’s near the top of the spectrogram.

    For a trill like the Dark-eyed Junco’s (bottom right p. 9 of the book), the pitch will be determined primarily by the frequency of that brief horizontal section of each repeated element, which is near 5 kHz. That is close to the frequency of the highest black key on a piano, so it will sound pretty high-pitched.

    I hope that answers your questions! If not, let me know, and I’ll take another stab at it.
