Harris—Birds of the Kansas City Region. 237 
visiting flock of any size was noted on March 11, 1914. Two 
specimens were examined in a hunter’s string in the spring of 
1916. 
CLANGULA ISLANDICA (Gmelin). Barrow’s Golden-eye. 
Very rare winter visitant. 
This northern bird seldom wanders so far south and there 
are but two authentic records of its capture in this immediate 
neighborhood. 
CHARITONETTA ALBEOLA (Linn.). Buftle-head. 
Irregular and not common migrant. 
Never of very frequent occurrence, this small duck is as likely 
to be met with in February as in May, returning from the north 
in late October and November. During some years several small 
flocks are seen and in other years none. The rivermen call this 
duck the Butterball and say that it does not occur as fre- 
quently as formerly. 
HERELDA HYEMALIS (Linn.). Old-squaw. 
Very rare winter visitant. 
Authentic records of the occurrence of this duck are few, 
though several of the river fishermen claim to know the bird 
and to have seen it several times. One specimen was taken by 
Bryant in 1893. 
Histrionicus HISTRIONICUS (Linn.). Harlequin Duck. 
Very rare winter visitant. 
There are but two records of the occurrence of this northern 
duck in this vicinity. One specimen was taken by Wm. An- 
drews on the Missouri River at the Eaton tower (date not 
available) and the other was killed at Lake City by Bryant in 
1887, 
OMEMIA AMERICANA Swainson. Scoter. 
Irregular winter visitant. 
River men claim to know this bird but the fact of its ae 
ence here was not authentically established until 1914. During 
the autumn flight of that year several dozen specimens were 
examined at different times. This was probably an exceptional 
invasion of this duck and the river hunters made the most of it.
