i888.] EvERMANN, Birds of Carroll County, Indiana. -iAj 



20. Glaucionetta clangula americana. American Golden-eye. 



Rare migrant; seen most often in March and April. 



21. Glaucionetta islandica. Barrow's Golden-eye. — A very rare bird 

 in this County. A female which I shot in Deer Creek, near Camden, 

 March 19, 1SS5, is, as far as I know, the only specimen of the species ever 

 taken in this part of the State. 



22. Charitonetta albeola. Buffle-head. — A more common migrant 

 than either of the last. A few probably remain in open places in the river 

 through the winter. 



z^. Erismatura rubida. Ruddy Duck. — A rare spring and autumn 

 migrant. 



24. Branta canadensis. Canada Goose. — Formerly an abundant mi- 

 grant, often stopping in wheat fields to feed, but of late years it is much 

 less common ; only a few flocks are seen flying over each spring and 

 autumn, and but rarely are any killed by the local sportsmen. On the 

 prairies to the northwest of Carroll County they are said to still stop in 

 considerable numbers. 



25. Olor columbianus. Whistling Swan. — A regular but rare mi- 

 grant, most often seen in the spring. One or more specimens are taken 

 nearly every spring on the Wabash near Delphi. 



26. Olor buccinator. Trumpeter Swan. — Less common than the 

 Whistling Swan. I remember but one specimen ; that was killed on Wild 

 Cat Creek, near Burlington, several years ago. 



27. Botaurus lentiginosus American Bittern. — While the Bittern 

 is probably a not uncommon migrant through the County, I have seen 

 very few within the County, owing no doubt to the fact that I was able to 

 make but few observations in regions suitable for such birds. Specimens 

 gotten at Lake Maxinkuckee April 15 and May 2 and 9, 1885. 



28. Ardea herodias. Great Blue Heron. — This Heron begins to 

 arrive from the Soutli quite early in the spring (April 8, 1884; February 

 14, March i and 18, 1S85), and remains until late in October. It seems to 

 be by far the most abundant Heron which visits us. At present there are 

 two large heronries in the County that I know of. The first of these is in 

 Adams township near the northern limit of the County, about six miles 

 north of the Wabash and about the same distance east of the Tippecanoe. 

 The other is in what is known as the Maple Swamp, in the southern part 

 of the County, about six miles south of Wild Cat Creek, or eighteen miles 

 from the Wabash. This swamp is made by the widening of a small 

 stream called Middle Fork, so that it covers an area of several hundred 

 acres. The lower portion of this swamp is covered with a heavy growth 

 of swamp ash and soft maple, and in the tops of these trees the Herons 

 build their nests. My first visit to this heronry was on June 12, 18S2. 

 We found more than a hundred pairs nesting there then, and their many 

 nests, some no longer used, presented a very interesting sight. Passing 

 by the swamp in winter when the leaves are off", the nests show very 

 plainly. As many as thirteen nests were seen in one tree, and many 

 other trees contained from three to ten nests each. I climbed tomanvof
