Coastal Diving Cormorant Wyvfin
Nesting Site: Zone F
Hunting Site: Zone 3
Aquadracius tridactylus evolved from Aquadracius urioportus after predators (Rostrovenator rostrus and Macrognathusensis dracokillus) within Zone 3 expanded their sizes and began hunting the wyverns. It has a similar body shape with similar behaviors to Aquadracius urioportus, but something with their instincts and morphology just seems a little off...
Aquadracius tridactylus has regained regular maintainable flight! This was not difficult to occur as the wings were already capable of temporary flight, but the wingspan has expanded to one hundred thirty centimeters (130cm) via the elongation of arm bones and has less dense bones to fly more lightly, also helped by their smaller stomach which also reduces body weight and passes meat through digestion more quickly. Their body length (including the tail) is one meter (1m) by comparison.
Aquadracius tridactylus will dig a den just outside of the beaches of Zone F, and will mate for life. They hunt solitarily and are flexible in the scenario that their partner dies, finding another mate and sometimes moving dens, but prefer staying with the same mate in the same area their whole life. Anywhere between two (2) and four (4) eggs are laid in the beginning of the wet season each year. Chicks are raised by both parents, which swap turns hunting for food and caring for the chicks, who part their ways at around eight (8) weeks of age and find a mate later in the year.Crest warts are a sign of status in males, and females prefer males with the most elaborate crests before choosing her mate.
Aquadracius tridactylus have also modified their hunting and navigation systems to counter their new predators. Hunting wyverns will fly no further than fifteen kilometers (15km) from land to fish, and dive no deeper than twenty meters (20m) underwater, swimming headfirst, holding their breath for one (1) minute at a time. Food items include Communoslontus populator,
Suboslontus communis, Suboslontus whiskerius, Suboslontus devilosis, Oslontus brycomi, Hexapiscus herbimendus, Hexapiscus glidus, Hexapiscus fugitatus, Hexapiscus predata, and Hexapiscus lunga. Aquadracius tridactylus will immediately leave the vicinity if a predator is observed underwater and will fly back to their den and regurgitate some of the food they have.
