CANADIAN FAUNA ON THE ALLEGHANIES. 



Mr. Trippes' note, already referred to, on " Birds found breeding 

 in the Catskills," makes mention of the following species, all of which 

 are further considered beyond: Regidus satrapa (Golden-crested 

 Kinglet), Sitta Canadensis (Canada Nuthatch), AnotJuira ' hyevialis 

 (Winter Wren), Dendrosca Canadensis = D. coeridescens (Black- 

 throated Blue W'arbler), Dendrceca coronata (Yellow-rumped War- 

 bler), Dendj'ceca virens (Black-throated Green Warbler), Jiinco 

 hyemalis (Slate-colored Snowbird). 



The wide faunal diversity between continuate regions indicated in 

 the above comparison of characteristic birds, is called for by the com- 

 plete and abrupt physiographical changes which give rise to the 

 Catskill range, the eastern end of which " stands isolated on three 

 sides by deep and broadly open valleys, as a mighty promontory, to 

 within ten miles of tide water in the Hudson River." 



How far southward the Fauna of the Alleghany range preserves 

 the Canadian characteristics possessed in the Catskills, and under 

 what restrictions and modifications, is an interesting question; but the 

 reply is not yet, although scattered notices of the occurrence in sum- 

 mer and, in some cases, the breeding of birds southward of their 

 usual range, in the Alleghanies, allow an insight into what it will be. 



Apropos to this subject are some remarks by Professor E. D. Cope 



in a paper entitled " Observations on the Fauna of the Southern 



Alleghanies ":* 



" In Giles County, E. Virginia, at an elevation of five thousand 

 feet, I observed in August, 1867, the following species of birds : 

 yiinco hyemalis. Dendroeca icterocephala [= D. PennsylvaniccL\ D. 

 Blackburnice. D. coei'idescens, D. inactdosa, D. virenSy Myiodioctes 

 Canadensis, M. niitralus [sic]. Panda Americana, Mniotilta varia, 



is common here [Esopus] and annoys me much by robbing birds' nests. Last summer [1881] a pair 

 built their nest in a Norway spruce that stands in a thick grove near a gentleman's country house 

 adjoining my place." I am myself almost positive of having seen one of these Crows, in June, near 

 Rondout, perched upon a spile far out in the here shallow river; and also feel almost satisfied that, 

 on different occasions, I have seen the Rough-winged Swallow at the same locality, where un- 

 doubtedly it occurs.
