The snowy heron is a rare plume bird seen occasionally along the coast.
Pulmonata are widely distinguished from a small number of Streptoneura at one time associated with them on account of their mantle-chamber being converted, as in Pulmonata, into a lung, and the ctenidium or branchial plume aborted.
The young lack the ornamental plume, and in them the head and neck are clothed with short black feathers, while the bill is yellow.

The air entrained by the fire plume from the lower layer into the upper layer is taken into account.
