Since Deneb is supposed to be the tail of the swan, (Deneb is Arabic meaning tail), it is that star at the end of the line on the left. The swan's wings should be equal length, which the vertical lines are, and of course the neck of the swan is much longer than the tail. Hence Deneb on the left. Also Deneb happens to be nearby of the Pelican and North American Nebula's.

<<In animal anatomy, a cloaca /kloh-AY-kə/ (plural cloacae /kloh-AY-see or kloh-AY-kee/ ) is the posterior orifice that serves as the only opening for the digestive, reproductive, and urinary tracts (if present) of many vertebrate animals. All amphibians, reptiles, birds, and a few mammals (monotremes, tenrecs, golden moles, and marsupial moles) have this orifice, from which they excrete both urine and feces; this is in contrast to most placental mammals, which have two or three separate orifices for evacuation. The cloacal region is also often associated with a secretory organ, the cloacal gland, which has been implicated in the scent-marking behavior of some reptiles, marsupials, amphibians, and monotremes.
Birds reproduce using their cloaca; this occurs during a cloacal kiss in most birds. Birds that mate using this method touch their cloacae together, in some species for only a few seconds, sufficient time for sperm to be transferred from the male to the female. For some birds, such as ostriches, cassowaries, kiwi, geese, and some species of swans and ducks, the males do not use the cloaca for reproduction, but have a phallus. One study has looked into birds that use their cloaca for cooling. The cloaca in birds may also be referred to as the vent. Among falconers the word vent is also a verb meaning "to defecate".>>
