Feather duster budgerigar Feather duster budgerigar Feather duster budgerigars ("Melopsittacus undulatus"), sometimes called budgerigar mops, are budgerigars that have a condition characterised by overly long feathers that do not stop growing at usual periods, giving the bird the appearance of a feather duster. This condition is sometimes known as chrysanthemum feathering. The contour, tail and flight feathers do not stop growing, and they do not have the necessary barbs and barbules for the feather's structure to interlock. The shaft (calamus) is also curved, and so the feathers appear deformed and fluffed out. Individuals with this condition often appear less alert than nest mates.

Calamus (poems) The "Calamus" poems are a cluster of poems in "Leaves of Grass" by Walt Whitman. These poems celebrate and promote "the manly love of comrades". Most critics believe that these poems are Whitman's clearest expressions in print of his ideas about homosexual love. The first evidence of the poems that were to become the "Calamus" cluster is an unpublished manuscript sequence of twelve poems entitled "Live Oak With Moss," written in or before spring 1859.
