writer's collection had a faint greenish tinge, while several observers 

 describe sets of pale pink or buffy white. 



Karely, spotted eggs are found. Wayne (1910) says: "Spotted 

 eggs are, however, very rare and I have found only four or five nests 

 containing them." The only spotted egg the writer has found is in 

 the set referred to above; of these, two are immaculate, while the 

 third is "faintly though distinctly speckled around the larger end 

 with reddish brown" (Dingle, 1926). 



Brewster (1885b) describes a set collected by the late Arthur T. 

 Wayne : "One is perfectly plain ; another * * * has two or three 

 minute specks which may be genuine shell markings ; while the third 

 is unmistakably spotted and blotched with pale lilac. Over most of 

 the surface these markings are fine, faint, and sparsely distributed, 

 but about the larger end they become coarser, thicker, and deeper 

 colored, forming a well-defined ring or wreath." 



Burleigh (1923) writes: "Unlike all the descriptions I had read, 

 and the few eggs I had seen, these were light pink in ground color 

 and dotted distinctly over the entire surface with light brown spots, 

 this almost forming a wreath at the larger end of one egg." These 

 eggs were found near Augusta, Ga., and the parent was secured. 



Wayne (1910) was of the opinion that two broods are raised in a 

 season. 



[Author's Note : The measurements of 50 eggs average 19.5 by 15.0 

 millimeters ; the eggs showing the four extremes measure 21.6 by 14.2, 

 20.8 by 16.0, 18.0 by 14.1, and 19.5 by 13.5 millimeters (Harris).] 



Plumages. — [Author's Note : Ridgway ( 1902) describes the juvenal 

 plumage of Swainson's w^arbler as follows : "Head, neck, back, rump, 

 upper tail-coverts, chest, sides, and flanks plain brown (varying from 

 broccoli to bister) ; rest of under parts whitish or dull pale yellowish, 

 more or less clouded with brown; middle and greater wing-coverts 

 indistinctly tipped with cinnamon-brown ; otherwise like adults, but 

 no trace of lighter superciliary nor darker postocular stripes." Speci- 

 mens that I have seen in this plumage are more nearly "cinnamon- 

 brown" than the colors named above on the back and wing coverts, 

 and the latter show very little evidence of cinnamon tips.] 



The postjuvenal molt, which evidently includes only the contour 

 plumage and the wing coverts, occurs early in the summer; I have 

 seen young birds beginning to acquire the first winter plumage as 

 early as June 12, and others that had nearly completed the molt on 

 July 20 ; these birds were not yet fully grown. Wayne (1910) writes : 

 "I have taken young birds which were as large as the adults and 

 which were acquiring their autumnal plumage as early as June 2, 

 but it must be borne in mind that the season in which these young 

 were taken (1906) was exceptionally advanced."
