576 APPENDIX. 



CATHAETES AURA. Turkey Buzzard. — Accidental. One taken at 

 Calais, Me., — George A. Boardman; two in Massachusetts, 18G3. 



CATHARTES ATEATUS. Black Vulture. — Accidental. One taken at 

 Swampscolt, Mass., in November, 1850, by S. Jillson; one at Glou- 

 cester, Mass., on Sept. 28, 1863, by William Huntsford; one in Hudson, 

 Mass. ; others seen, — S. Jillson; one near Calais, Me., — G. A. Board- 

 man. 



FALCO SACEE. Jer Falcon. Iceland Falcon. — Rare winter visitor, al- 

 most accidental in southern portions. One killed at Seekonk Plains, 

 Mass., about 1840, by Jillson ; one taken in the winter of 18G-1-0, near 

 Providence, R.I., by ]\Ir. Newton Dexter. 'J"he two species heretofore 

 considered distinct — viz., Fulco Candicans and F. Islandicus — are 

 now considered as belonging to the present species. 



AECHIBUTEO SANCTIJOHANNIS, Black Hawk; and AECHIBUTEO LA- 

 GOPUS, Eough-legged Hawk — J. A. Allen gives, in his article on the 

 " Rarer Birds of INIassachusetts," the following extract, from a letter 

 written by Dr. William Wood, in relation to these species, to prove that 

 they are identical : — 



"I have," he says, "all shades of color, from the light to the black, 

 and I am unable to find the dividing line ; both have the same measure- 

 ments, the same claws and bill, the same habits, come and leave at the 

 same time, and hunt together. I have them aknost black, with the faint 

 markings of the lighter l)ird, showing, to my mind, that the lighter mark- 

 ings become extinct as the black increases, or as the bird increases in age. 

 Those who claim that they are distinct say, that in some localities the 

 Rough-legs are common, and no Black Hawks are to be seen. This 

 proves nothing. The young of the Red-throated Diver are very common 

 in Long-Island Sound, yet the adult is never seen there. So it is with 

 the Crested Grebe : the young are found here in winter, never the 

 adult." 



In another letter. Dr. Wood says: " The Rough-legged Falcon and 

 Black Hawk are the same. I have taken and examined, I presume, forty 

 specimens. They are the same bird, but not of the same age. The black 

 is the adult. So gradually do they become more black till jet-black is 

 reached, that I will defy any one to draw the separating line." 



STEIX PEATIKCOLA. Barn Owl — Given by Thompson, on authority 

 of Dr. Brewer, as being not only found in Vermont, but also breeding 

 there. This is, of course, incorrect. Accidental visitor from the South. 

 f One taken in Lynn, Mass., about I860, by Mr. James Teal ; one taken 

 at " Sachem's Head," Conn., Oct. 28, 1865, — Dr. William WoDd; one 

 at Springfield, Mass., May, 1868, — J. A. AUen.
