This call is also sometimes given by both members of at "duetting" pair during breeding season or during displays. Female has two recognized calls: a soft ki or krr that may serve to indicate the location of female and a louder "wail" call. Juveniles may give a begging call or "hunger shriek," which souds like a thinner, higher pitched version of the adult wail call. This call may be given by several juveniles at once, and may also be used by fledglings that have left the nest but are still dependent on parental feeding. Alas, I cannot find the recording that came with BFL for hawks, nor recall if juvenile calls were included. Here's what Bent says (see http://home.bluemarble.net/~pqn/ch1-10/coopers.html#Voice ): Voice.--The ordinary alarm note, heard about its nest, is a loud, metallic, cackling note, similar in form to the corresponding note of the sharp-shinned hawk, but louder and on a lower key. I have always written it kak, kak, kak, kak. Others have called it cac, cac, cac, or cuck, cuck, cuck. It is rapidly uttered with considerable emphasis. As the female leaves the nest she sometimes gives a loud scream of fright or anger. I've made a stab at finding recordings at the Cornell Lab ( lost that website) , as well as the Borror Lab at Ohio State (http://blb.biosci.ohio-state.edu ). It appears the only way to access stuff at Cornell is to buy it. I can't make anything work at Borror. Maybe smarter people than me can make these sites work.
