Mated pairs of cranes engage in "unison calling". The cranes stand close together, calling in a synchronized and complex duet. The female makes two calls for every one from the male. Sandhill cranes' large wingspans, typically 1.65 to 2.30 m (5 ft 5 in to 7 ft 7 in), make them very skilled soaring birds, similar in style to hawks and eagles. [17]
The pelvis is, in general, different between the human female and male skeleton. [14] [15] Although variations exist and there may be a degree of overlap between typically male or female traits, [14] [15] the pelvis is the most dimorphic bone of the human skeleton and is therefore likely to be accurate when using it to ascertain a person's sex ...
Clockwise from top left: blue cranes, sandhill cranes, grey crowned cranes, and red-crowned cranes Cranes are tall wading birds in the family Gruidae. Cranes are found on every continent except for South America and Antarctica and inhabit a variety of open habitats, although most species prefer to live near water. [ 1 ]

Crane mythology can be found in cultures around the world, from India to the Aegean, Arabia, China, Korea, Japan, Australia, and North America. The Sanskrit epic poet Valmiki was inspired to write the first śloka couplet by the pathos of seeing a male sarus crane shot while dancing with its mate. [24] [25]
This list of related male and female reproductive organs shows how the male and female reproductive organs and the development of the reproductive system are related, sharing a common developmental path. This makes them biological homologues. These organs differentiate into the respective sex organs in males and females.
A subpubic angle of 50–82 degrees indicates a male; an angle of 90 degrees indicates a female. [2] Other sources operate with 50–60 degrees for males and 70–90 degrees in females. [ 1 ] Women have wider hips, and thus a greater subpubic angle, in order to allow for child birth .
Pelvimetry is the measurement of the female pelvis. [1] It can theoretically identify cephalo-pelvic disproportion, which is when the capacity of the pelvis is inadequate to allow the fetus to negotiate the birth canal. However, clinical evidence indicate that all pregnant women should be allowed a trial of labor regardless of pelvimetry results.
