' Bishop {loc. cit.) claims further that there are color differences in the 

 Juvenal plumage. Oberholser (19186, p. 465) upholds the validity of 

 hooveri, asserting "that it differs from Dendraica coronata coronata 

 not only in its larger size but in the coloration of male, female, and 

 even young." Kidgway (1902, p. 548, footnote) and Riley (1912, 

 p. 70) each refuse recognition to hooveri. 



The series assembled by myself in the present connection demon- 

 strates the average size differences claimed to exist. I fail to appreciate 

 any differences whatsoever of color or pattern between adult males 

 and females of the two lots. The juvenal plumages I have been unable 

 to compare. As regards immatures in first winter plumage, examples 

 of hooveri are slightly (but distinguishably) darker, more brownish, 

 than comparable specimens of coronata (see in this connection Swarth, 

 1911, p. 99).

 Very few seen at any point, and none under circumstances that 

 would lead to the belief that the species was breeding east of the 

 coastal mountains. First noted at Flood Glacier, where it may, per- 

 haps, have been breeding, or where the birds seen may have wandered 

 from nearer the coast. The first was taken on July 28 (no. 40194) 

 and another on August 3 (no. 40195), both molting from juvenal to 

 first winter plumage. Several more were seen. A male in first winter 

 plumage throughout (no. 40196) was taken at Great Glacier, August 

 14, and others were observed at the same point. At Sergief Island 

 but one or two were noted, the last on September 1.
