Burns—On BROAD-WINGED HAWK. Qi 
texture, pale blue in color and even a few shell marks present ; 
this could be subjected to considerable pressure without break- 
ing, immediately after removal. 
Old works on the science almost invariably give the dimen- 
sions of the B. lineatus for B. platwpterus, and the archaic 
methods of measurement were not wholly to blame. Errone- 
ous identification is responsible for a great many specimens of 
the former labeled as the latter. When Chas. C. Richards 
measured the Lorenzo Blackstone collection of Broad-winged 
Hawk eggs in the State Hall, Norwich Free Academy, he 
also measured the smallest set of Red-shouldered Hawk’s eggs 
in a series of 37 sets. They were 1.96x1.64, 1.97'%2x1.68, 
2.0614x1.86%4, and were the smallest he ever saw of the spe- 
cies. His own smallest specimens in a set, of the same bird, 
are 2.02x1.64, 2.04x1.66, 2.0014x1.65. In the matter of ex- 
change, when a so-called Broad-wing’s eggs runs over 1.60 in 
width, he thinks the collector’s reputation should be O. Kd. 
That the dimensions of the eggs of the two species overlap, 
there can be no question, and in a region where both species 
occur, the oologist cannot be too careful in his identifications. 
H. W. Beers took a set of eggs in Fairfield Co., Ct., on 
May 14, 96, which is unique in the wide range in individual 
shells, 2.08x1.53, 1.92x1.55, 1.57x1.27, the last named being a 
runt measuring little more in length than the smaller diameter 
of the first egg. An egg collected by T. and J. Flannagan in 
Kent Co., R. I., on May 19, °06, in a maple at the edge of a 
swamp takes the palm for dimensions. It is 1.30x.96 and is 
well marked with splashes and blotches of rufous brown and 
lilac. The texture of the shell is coarse and somewhat gran- 
ulated and a little malformed on one side, and of a dull finish. 
The nest was found on the 13th with the bird sitting on this 
runt, which proved infertile. |. H. Flanagan states that he 
has more than 200 sets of hawk’s eggs of the different species 
of his own take and this is his only runt in hawk eggs. Prob- 
ably the parent would have proved an aged bird, perhaps un- 
mated.
