some dead branch or in a patch of fallen branches, generally but little 
concealed.” 
Hylocichla Alicia? Bicknelli Ridgw. Bicknell’s Thrush. 
Regarding this Thrush little at present can be said beyond what 
has already been made public — by Mr. Ridgway in his introduction 
of the bird,* and by the writer in the paper previously cited. Since 
the latter appeared, however, the Slide Mountain was again visited 
by the writer, in company with Dr. A. K. Fisher, and the bird met 
with as before; but although a night was passed on the mountain, 
and an afternoon and morning spent in exploration, with this bird 
directly in view, a single specimen only was secured. This result 
was owing to the difficulty of detecting the birds in the dense balsam 
growth they principally inhabited before they had been startled by 
the unavoidable sound of approach; and not seldom were they heard 
singing at close quarters as secure as if out ot range. Although no 
one of this species was actually identified in the act of singing, cir- 
cumstantial evidence seems demonstrative that a song must be at- 
tributed to it which was neither that of the Hermit, or Olive-backed 
Thrush, — at least, differed from the usual songs of these species, both 
of which were to be heard singing at the same time, — but was very 
similar to that of the Gray-cheeked Thrush, as the latter is heard on 
its spring migration.. This granted, the bird may be considered com- 
mon about the mountain top. The songs referred to were, in fact, 
like that, as I recalled it, of the type specimen of H. ' Bicknelli, which 
was shot while singing. 
The dimensions of the single specimen secured agree closely with 
those ot the two which were previously taken, and are as follows in 
inches and hundredths : length, 7. 22; wing, 3.60; tail, 2.90; tarsus, 
1.20; middle toe, .67; bill, culmen and from nostril, .53—38. The 
length of the original Slide Mountain specimens was 7.28 and 7.40 
inches, but the latter figures are excessive as the bird was limp when 
measured. The singular shape of the bill of these specimens which 
was remarked upon by Mr. Ridgway, does not hold with the latest 
taken example. In this, the bill, as compared with the former, is less 
slender, with the base of the culmen instead of being depressed 
plainly elevated in outline, so much so, indeed, as to suggest an 
abnormality. 
Hylocichla ustulata Swainsoni (Cab.) Ridgw. Olive backed Thrush. 
Not uncommon on the mountains, especially in the balsam woods 
of the Slide, and in full song. An adult male taken at the top of
