1827. Vigors and Horsfield, `Transactions of Linnaean Society,' vol. xv. p. 204:

"The settlers call this bird the Laughing Jackass. I have also heard it called the Hawkesbury-Clock (clocks being at the period of my residence scarce articles in the colony, there not being one perhaps in the whole Hawkesbury settlement), for it is among the first of the feathered tribes which announce the approach of day."

1846. G. H. Haydon, `Five Years in Australia Felix,' p. 71:

"The laughing jackass, or settler's-clock is an uncouth looking creature of an ashen brown colour . . . This bird is the first to indicate by its note the approach of day, and thus it has received its other name, the settler's clock."

1847. L. Leichhardt, `Overland Expedition,' p. 234:

"I usually rise when I hear the merry laugh of the laughing- jackass (<i>Dacelo gigantea</i>), which, from its regularity, has not been unaptly named the settlers'-clock."

1848. J. Gould, `Birds of Australia,' vol. ii. pl. 18:

"<i>Dacelo Gigantea</i>, Leach, Great Brown King Fisher; Laughing Jackass of the Colonists."

1855. W. Howitt, `Two Years in Victoria,' vol. i. p. 58:

"You are startled by a loud, sudden cackling, like flocks of geese, followed by an obstreperous hoo! hoo! ha! ha! of the laughing jackass (<i>Dacelo gigantea</i>) a species of jay."
