The Warbler family, _Sylviidae_, is a large one, found all through the Eastern Hemisphere. One migratory species crosses Behring Strait each year to summer in Alaska. As no less than 79 Australian small birds have been grouped in this family, it is of considerable importance to our bird lovers. At the head of the family, we have an exact representative of the Reed-Warbler of Europe in the delightful plain-brown songster which charms all who frequent river sides. Its song is "louder and more melodious than that of any of its European relations except" the Reed-Warbler. It is a welcome spring visitor, and can be heard on any spring or summer day in the Botanic Gardens, or in any reed bed by stream or lake. The next bird is the Australian representative of the Fantail-Warblers (_Cisticola_). These birds are related to the Tailor-Bird. Much has been written of the Tailor-Bird of India which so cleverly sews leaves together to enclose its nest, but few know we have a bird that does similar work when building its nest. Dr. Sharpe has decided that our bird is identical with an Indian species, so we must take the Indian name--Golden-headed Fantail-Warbler. This bird moults twice a year. At the autumn moult, it obtains a long tail and a streaked crown. The four Australian species described by Gould are now known to be but different forms of the one species which undergoes seasonal change. Speckled Jack, the Speckled Warbler (Little Field-Wren), is a tame little bird with a pleasing song. Its chocolate-colored egg used to be much valued in the days when schoolboys collected eggs. It walks instead of hopping. The Yellow-tailed Tit-Warbler (_Acanthiza_) is a member of an Australian genus, which has been split up into 27 species, all of which, except a New Guinea form, are restricted to Australia. Some are pleasing songsters. The two-storied nest of the Yellow-tail is well known and is peculiar. What is the use of the upper nest--for the male to rest in, to delude the cuckoo, or what? These birds are not Tits (_Paridae_). They have been called Thornbills by Mr. A. J. North. The name Tit-Warbler has been adopted by the "names" sub-committee of the Royal Australasian Ornithologists' Union, pending the completion of the Australian Check-List. The common White-browed Scrub-Wren is not a Wren, but is a Warbler. He is the best known of the genus, though even he is seldom seen. His dark-brown color leads one to suspect a dark scrub as his dwelling place. Though common in places, he is seldom noticed, but if you sit down in a quiet scrubby corner, his inquisitiveness will often impel him to run almost over your feet. Some light spots on the shoulder and the white eyebrow will assist you in identifying him. His mouse-like run further assists in identification.
