Falco peregrinus
Dec. 21. 4 mi. E, 1 1/2 mi. S. of Port Hueneme, Ventura Co.,
[illegible] in full adult plumage was perched
in top of eucalyptus trees along Caspar Road.
A turkey vulture was perched nearby in
another tree top; when it took off it
sailed close by the duck hawk which
then flew -- but without either bird
making any overt act toward the other.
