[<thornius@xxxxxxxxxxxxx>]

I caught a Female Northern Cardinal in flight as i was photographing today and 
noticed in the picture that her head crest was raised as high as she could get 
it.  Is it possible that these raised head crests in the birds that have them 
serve a similar purpose as the vertical stabilizer in an airplane?  This 
picture can be found at  www.imagestation.com  in the album Thorns Birds, 
picture # 117.

Good Birding!
