Plumulaceous barbs

 Any guesses on who this feather belongs to?

 Found in Sebastopol on 10 June 2012 


Note the plumulaceous barbs at the base of the feather — the loose, downy parts that are soft and fluffy.  They aid in insulation.



Our best guess is Red-shouldered Hawk (Buteo lineatus).  I wish I had better photos of a Red-shouldered Hawk, but here are a couple from our yard in Sebastopol:

Note the black tail feathers with distinct white bands.


Can you find the hawk in the photo below?


This individual was perched very high in a redwood tree.  Below is a zoomed in view.


Red-shouldered Hawks can be seen year-round on Bodega Head, but they are less common than Red-tailed Hawks.

  1. That's what I was going to guess. Red-shouldered hawk. There are those little flecks of reddish brown...

    It is just wonderful how you turn a discarded feather into a vocabulary expander. Plumulaceous.It almost sounds like an aboriginal word. Next month, we are going to visit Purnululu National Park(also known as the Bungle Bungles, which will make us Purnululaceaous.
