Recall that「bird」is also a euphemism for the male human penis, in this case with an EXTENDED NECK AND HEAD whilst engaged in a courtship display, with prepuce skinned back and down,「surrounding on all sides」the extended head with HIGH AMBITIONS. Further note that this type of 'head' is unable to actually voice any sounds, since it lacks vocal chords, among other anatomical differences when compared with the head above one's shoulders.
　A STORK is a bird that is not able to make any throat sounds, no bird calls, no vocalizations.
　Elements depict a bird with wings the shape of the element「surround on all sides」with an「extended neck and head.」CRANES fly with neck outstretched (not retracted, such as with a heron's flight posture). During「courtship displays」CRANES also spread their wings widely and「extend the neck and head」in a「surrounding」pose, displaying HIGH AMBITION.
　「Surrounding, courtship display」depicts the raised, outspread wings of a CRANE while seeking a copulation partner:「Of all the behaviors of cranes, none is as spectacular or as well-known as their elaborate and enthusiastic dancing. …All species of cranes dance. It is apparently an ancient and complex behavior within the family, and serves a variety of functions (Masatomi 1994). Dancing is undertaken by even very young birds as a part of their behavioral and physical development. Unpaired subadult birds probably dance more than other age groups. For these birds, dancing facilitates the processes of socialization and pair formation. …Among pairs, it may serve to maintain pair bonds and synchronize sexual response prior to breeding. New pairs dance during courtship. …The pattern and intensity of dancing vary somewhat among the crane species, but the dances of all cranes consist of long and intricate sequences of coordinated bows, leaps, runs, and short flights. …Crowned Cranes perhaps dance most distinctively, bobbing their heads up and down prior to bowing, spreading their wings, leaping and flapping their wings, then often landing and circling one another. The sequence of courtship dancing among Blue Cranes has been observed to last from half an hour to as long as four hours (Van Ee 1966). The dance of the Demoiselle Crane has been described as 'more balletlike' than those of the Gruinae species, with fewer, less theatrical jumps (Johnsgard 1983). Among the Gruinae cranes, dancing is slightly more deliberate, and punctuated often with high, flapping leaps.」　[　https://www.npwrc.usgs.gov/resource/birds/cranes/behavior.htm 2012-12-27　]
