In cities it is said to be of some use in destroying Eng- lish sparrows. Study the prob- lem in your own locality. The number of our most valuable small birds — chickadees and wrens — which the shrike kills places it decidedly on the questional)le list. Family VireonidcE (vireo, " a greenfinch ") — the vireos or greenlets. These birds of the terminal foliage and pen- sile nests are among the best of our orchard and roadside insect police. We may certainly make the acquaintance of at least three of the seven common species. Red-eyed vireo — Vireosylva olicdcea. Warbling vireo — Vireosylva gilva. Yellow-throated vireo — Laniinreo fldcifrons. Family Mniotiltida (mnion, "moss"; tiltos, "pulled out") — warblers. To make the first acquaintance with this interesting and difficult family we may begin with four of the common resident s^jecies. Black-and-white warbler— Mniotilta vdria. Y^'ellow warbler — Dendroica cestwa. Ovenbird — Scurus aurocapillus. American redstart — Setopliaga ruticilla. Family Troglodytidcs (troglodytes, "cave dweller") — thrashers, wrens, etc. Mocking bird —Mimus polyglottos. This offers the problem of a rare. Fig. 24.
