84 The Wilson Bulletin — No. (i^. 



We fouiul by roi)oatefl trials, vorifled by the capture of specimens, 

 that careful attention could always separate the two species, when- 

 ever the conditions of observation were at all favorable. A closely 

 discriminating eye can tell them by the difference in flight, as Saun- 

 ders several times demonstrated, '['o the less acute, the soft brown- 

 ish suffusion over the throat and breast of the Rou,i?h-wing, instead 

 of the sharply defined breast bar of the r.ank and the slightly more 

 reddish cast (more appreciable in life than in nmsenm specimens) 

 are quite suthcient to separate the two s])ecies. The slightly super- 

 ior size of scrripeiuiin, though sometimes quite ai)pareut, is not al- 

 ways sutHciently marked fo.r ready recognition. 



Though (luite a number were taken, all were juveniles and with- 

 out the characteristic roughness on tlie i)rimaries that gives them 

 their distinctive name. Seemingly, this i)eculiar feather specializa- 

 ti(m is only ac<|uired with age, and we have sjiring birds that are 

 entirely without it and others on whicli it is but sliglitly marked.

Connnon on nearly all visits except those of October in 1905 and 

 i!)0(). It seems also to be present during the winter in considerable 

 numbers, and Gardner reported them at various times during the 

 winter of 190(3-7 and 1907-8. We saw large flocks March 9-10, 1907. 

 September 5, 1907, we saw a flock start out over the lake with the 

 evident intention of crossing, but the stiff south wind proved too 

 strong for them and they returned. Very connnon May 1-."?, in large 

 flo<-ks, distrilinted all over the Point. 



HYPOTHETICAL. 



Liiiiiiis horcaiis. — Northern Shrike. 



Though this species undoubtedly occurs, we list it "hypothetical" 

 for the sake of consistency as we have no absolutely authentic rec- 

 ord of its occurrence. Gardner, on being shown a Migrant Slirike. 

 Vei)orted having seen, in the winter, birds like it but larger. 



ino. '*Laiiiiis liKloriciaiiiis iiii(/r<ins. — JNIigrant Shrike. 



Of late years we have found this species almost scarce about De- 

 troit, nor has it been common on tlie Point. From August 24 to 

 September 6, 1907, w^e noted single individuals several times ; once 

 near Sturgeon Creek, at the Base, again about half way out, in the 

 vicinity of some old hennery building ; and on two or three occas- 

 ions, in the deserted fields near the end of the Point. September 6, 

 1907, a juvenile was brought to us by one of the residents. We have 

 seen them on no other occasions.
