54 AVIFAUNA COLUMBIANA. 



Family VIKEONID^} : Greenlets. 



70. (96.) Vireo olivaceus (Linn.) Vieill. Red-eyed Greenlet. 



A summer resident, and decidedly the most abundant of all the wood- 

 land birds during that season. It is found in every piece of high, open 

 woods from the 15th of April to the 20th of September, and is one of 

 the most industrious and persevering of songsters, whose voice not 

 even the noon of the dog-days can still. [170] 



Vireo philadelpMcus, the Brotherly-love Greenlet, is undoubtedly a 

 rare inhabitant of the District, liable to turn up any spring or fall. 



71. (97.) Vireo gilvus ( Vieill.) Bp. Warbling Greenlet. 



A common summer resident, arriving April 20 and remaining until 

 September 20. It frequents orchards, gardens, and parks, sometimes 

 swampy copses, but was specially abundant in the city, breeding in the 

 tall sycamores and poplars, before the irritating English Sparrows 

 diminished the numbers of the gentle, silvery-tongued creatures. [174] 



72. (99.) Vireo flavifrons Vieill. Yellow-throated Greenlet. 



A summer resident, abundant in high, open woods. Arrives April 

 25; remains until September 25. The hanging basket in which the 

 Greenlet cradles its hopes is one of the most beautiful of the pensile 

 structures which birds of this family fabricate, being elegantly stuccoed 

 with lichens, like a Gnat-catcher's or Humming-bird's. [176] 



73. (98.) Vireo solitarius Vieill. Blue-headed Greenlet. 



This is much the rarest of the Greenlets ; we have seldom observed 

 it, and only during the migration; but some individuals doubtless breed 

 with us. Arrives in the spring, April 25, and is sometimes found until 

 October 20. It is a woodland species, like the Eed-eyed and Yellow- 

 throated. In the spring of 1882, like most other migrants, it was more 

 numerous than usual. [177] 



74. ( — .) Vireo noveboracensis (Gm.) Bp. White-eyed Greenlet. 



By a pure oversight this species was omitted from the original edition of 

 this catalogue, for we were perfectly familiar with the energetic, obtrus- 

 ive little inhabitant of the shrubbery, where it resides in large numbers 

 during the summer. It arrives late in April, and leaves the latter part 

 of September. It has had hard work to get properly represented ; we 

 remember looking for it when the proofs of Mr. Jouy's list were sub- 

 mitted to our inspection, and making sure that it went in. [181] 



Family LANIID^ : Shrikes. 



75. (95.) Lanius borealis Vieill. Great Northern Shrike, or Butcher Bird. 

 Very rare, and scarcely to be seen except in severe winter weather. 



We have only known of two or three specimens procured in the Dis- 

 trict, which appears to be about the southern limit of the species. [186]
