Nest and Eggs of Black-throated Blue Warbler. 



More about the Eggs of Black-throated 

 Blue Warbler. 



The set of eggs of the Black-throated 

 Blue Warbler sent you by Mr. Stone 

 for comparison with the set taken by 

 himself, fsee Oologist for February, 

 1904; pp. 22.) was one of my own col- 

 lecting and it may be of interest to 

 your readers to have other comparisons 

 made. My tirst find of this Warbler 

 was at Cincinnatus, N. Y. on June 11, 

 1895. At the time I was in an open 

 tract in a piece of woods on a side hill 

 grown up to bushes, ferns and small 

 saplings with here and there a fallen 

 log and brush pile, when I was attract- 

 ed by the alarm notes of this Warbler 

 and a short search revealed the nest, 

 which was built on a fallen limb rest- 

 ing in some low beech saplings. It 

 was placed 18 inches above the ground 

 and was composed of rotten bits of 

 wood, vine bark and flowers from 



weeds and partially covered with co- 

 coons. The lining was small black 

 roots and hair. The female was shot 

 to make sure of identity. 



All of the several nests I have exam- 

 ined in this locality were almost an 

 exact counterpart of this nest and 

 almost invariably rested upon fallen 

 dead limbs but concealed by weeds or 

 bushes. I think the nest which was 

 sent you by Mr. Stone was rather more 

 compact than when found from the 

 fact that it had been tightly wound 

 with thread. There were four eggs in 

 the above described nest. One unfor- 

 tunatly was broken. The other three, 

 which were slightly incubated, meas- 

 ured .63 X .52, .66 X .53, .62 x .50 

 which, you will note, were consider- 

 ably smaller than the set which I sent 

 to Mr. Stone. They also are unlike 

 any of the other eggs which I have 

 examined. There were no brown 

 markings but the eggs are covered
