Storm's Stork (Ciconia stormi)
A small, worldwide family of very large birds with long powerful beaks. They have long legs, broad wings, and short tails. They feed mostly on fish or small animals, which they catch while stalking quietly in open wet areas.
Storks are strong fliers and several species migrate over large distances. They are experts at soaring on thermals and often circle high in the sky, gaining height for easy travel, or searching for likely feeding places.
There are four resident species in the Greater Sundas and three doubtful vagrants.
