the figures. In addition to the preceding comments, I am, therefore, listing 
each species indicating my conclusions as to its status and relative abun- 
dance based upon the ten years of observations. 
Black and White Warbler — A common migrant. Its ease of identifica- 
tion probably has some bearing on the number recorded. 
Prothonotary Warbler — A rare migrant and summer resident. The 
relative abundance shown in table 2 is probably not representative because 
not enough records were made in habitats it frequents. All my observations 
of this warbler were in willows near or over water. 
Golden-winged Warbler — A rare migrant and rare summer resident. 
I saw four in Memorial Park Cemetery May 9, 1936, and one on May 16, 
1948, just off Sheridan Road a block from my home. 
Brewster’s Warbler — Rare. Saw one in Calvary Cemetery May 19, 
1945 in a low bush at a distance of less than six feet. 
Lawrence’s Warbler — Rare. The three listed in table 2 were seen 
with the four golden-winged warblers mentioned above. 
Tennessee Warbler — An uncommon migrant. Probably more common 
than my record indicates because it is seen most often in the tree tops. 
Orange-crowned Warbler — An uncommon migrant. Like the preceding 
species, probably more plentiful than indicated because of dull plumage 
and difficulty of identification. Table 2 shows that I have recorded both 
of these warblers the same number of times and the same number of years. 
“Birds of the Chicago Region” refers to the Tennessee as “common” and 
the orange-crowned as “uncommon.” 
Nashville Warbler — A common migrant. Identification is not always 
obvious. 
Northern Parula Warbler — An uncommon migrant. I have seen it 
only five years out of ten. 
Eastern Yellow Warbler — A fairly common migrant and a summer 
resident. Although it is ordinarily regarded as “common,” for some reason 
my average observations is only a fraction over seven per year. 
Magnolia Warbler — One of the four most abundant migrants. 
Cape May Warbler — A fairly common migrant. The late W. I. Lyon 
had a theory that the warblers’ northward advance was influenced some- 
what by the blossoming of fruit trees, but this is the only one I ever 
thought of as seeming to have a preference for feeding among the blossoms 
of fruit trees. 
Black-throated Blue Warbler — An uncommon migrant. I have seen 
only 16 in the past ten years and none were recorded in 1936 and 1940. 
Myrtle Warbler — An abundant migrant. The percentage shown is 
probably too high due to the fact that it appears early in large numbers 
when no other members of the family are present and hence no competition 
in recording it. 
Black-throated Green Warbler — A common migrant. Surprising that 
I saw none in 19389.
