Prairie Falcon 'choanal slit'

[SeEttaM .]

Did you know that falcons have a 'choanal slit' -it is located in the roof of it's mouth and it connects to the bird's sinuses (source:  the ModernApprentice.com -a falcony not a wizard site).  So I got a photo that shows this structure inside the beak of the Prairie Falcon I photographed this week.  Yup, I didn't know what that slit in the roof of it's mouth was so had to research it.  Now I have posted that photo, and another close-up that shows nicely the yellow eye ring found on adult Prairie Falcons, onto my Birds and Nature blog for those into this rarely seen detail.
