DENDRffiCA VIRENS 



representation of Dcndrccca, lio« ever, we should not forget that 

 several Eastern species, properly speaking, are not so exclu- 

 sively restricted as has long been supposed. The recent thor- 

 ough ransacking of the mountains of Colorado, by several 

 well-trained ornithologists, has shown that various species 

 reach across the Plains to the Rocky Mountains, and even pen- 

 etrate their fastnesses — not as mere stragglers, but as regular 

 migrants. Such species are D. striata, D. coerulea, D. black- 

 hurnice, and D. maculosa, which I shall consequently include in 

 the main text of the present work, as reaching the confines of 

 the Colorado watershed.
