CIVIC BIOLOGY 



Family Ampelida (ampelus, "a vine") waxwings. The cedar wax- 

 wing, Bombycilla ccdrorum, known also as the cherry bird, is noted for 



destruction of cankerworms 

 in our orchards. 



Family LaniidG. (lanius, 

 " butcher ) shrikes. The 

 loggerhead shrike, Lanius lu- 

 dovicidnus, frequents hedge- 

 rows and borders of fields, 

 where it feeds upon insects, 

 field mice, and small birds. 

 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 questionable list. 



Family Vireonidcs (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 vireD Vireosylva olivdcea. 

 Warbling vireo Vireosylva gilva. 

 Yellow-throated vireo Lanicireo fldvifrons. 



Family Mniotiltid& (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 species. 



Black-and-white warbler Mniotilta vdria. 

 Yellow warbler Dendroica 'cestwa. 

 Ovenbird Scurus aurocapillus. 

 American redstart Setophaga ruticilla. 



Family Troglodytids. (troglodytes, "cave dweller") thrashers, wrens, 

 etc. Mocking bird Mimus polyglottos. This offers the problem of a rare
