Feather detail and more

  

Cooper's Hawk (Astur cooperii) feeding while perched on a tree branch in Cotati on 18 March 2025.  [You can click on the image for a larger version.]

In addition to feeding on prey, this bird happened to be quite vocal as we were walking by.  The calls were not the more-often-heard cak-cak-cak variety, but instead what are sometimes described as whaaa calls, more often attributed to females.

If you're interested, I recorded a very short audio clip for the record -- see below.  [If you can't see the video player in the e-mail, click on the title of the post above to find it on the NHBH web page.]  The lighting isn't the best, but at the time I was more focused on trying to record the sound.  You might need to turn up your volume a little bit.


Spring is on the way!

Thanks for making the call recording ... Now if only all other bird calls were as easily available :)

Hi, Beth!

That's a fun way to remember the call!

Whaaat's up, hawk?! :)

The hawk's call reminded me of whirring call that mourning doves sometimes make. That would be a slick bit of mimicry for a hawk to make, but I doubt an actual mourning dove would be as easily fooled as I might be.

We just got a Coopers Hawk in our neighborhood, Cherry Valley Petaluma. We've had red shouldered for years and occasional red tail but the Coopers just started hanging around with it's typical call - will see if it does the call like yours.
