Suborder ARDEAE.

Suborder ARDEAE.

This suborder differs from the preceding in having a pair of tracheo-bronchial muscles which control the syrinx and give the possessors vocal powers. The suborder is holorhinal; the mandible is not produced beyond its articulation with the quadrate and there is only a single incision on each side of the posterior border of the sternum ; the cervical vertebras number eighteen or twenty; the ambiens and accessory femoro-caudal muscles are absent and the femoro-caudal generally very small; the spinal feather-tract extends far up the neck, in one genus, Ixobrychus, the whole hind-neck being naked.

The suborder contains three well-defined families, of which but one, the Ardeidae, is represented within our area.
