Genus CYANECULA, Brehm, 1828.
The genus Cyanecula contains the Blue-throats, birds which are very closely allied to the English Robin. The Blue-throats may be recognized by their very short tail, which is only twice the length of the tarsus, and by the chestnut colour of the basal half of the tail. The males, moreover, have the chin and throat a brilliant blue. The females are of a dull colour, but have the tail chestnut as in the male.
The Blue-throats feed on the ground, and are generally found in India in thick grass-jungle, arid more rarely in open country. They prefer swampy ground. They run well, elevating the tail on arriving at the end of each short course of running, and sometimes expanding it. They are said to be good songsters. They breed in holes on the ground, and lay blue eggs spotted with reddish brown. The only two species of this genus are highly migratory.
