lyittle Twin Lakes, Hancock county, in the season of 1883, not 

 many miles from where some good finds in the way of sets of 

 Whooping Cranes were made. This was positively Olor buccina- 

 tor. The nest was placed on a large tussock in a marshy slough 

 or creek, and had been used for years by the swans, as I was cred- 

 ibly informed; but the nest mentioned above, so far as I am 

 aware, was the last in that locality. During the earlier days the 

 Trumpeter Swan was not an uncommon summer resident, being 

 occasionally found nesting in some remote and hidden place, and 

 as late as 1875 there were a few pairs known to breed on the 

 headwaters of the Des Moines River. Of course the species of 

 Swans have been somewhat confused in the minds of untrained 

 observers, but to one familiar with the two American species there 

 w'ould be no chance of mistake. For many 3^ears I have not seen 

 a Trumpeter Swan in the State."

 mounted by myself in museum of Iowa State Normal School" 

 (Walters). Jackson — "tolerably common transient" (Giddings).

 souri flying over from the Nebraska side of the river to the Iowa 

 side, and in other directions, at numerous times. The following 

 dates are noted by me in particular: April 5, 1893; Sept. 30, 1894; 

 April 15, 1896; Sept, 20, 1897, ^'^'^^ ^^ various times since. T/icy

Order HERODIONES. Herons, Storks, Ibises, etc. 

 Sub-order IBIDES. Ibis series. 

 Family IBIDID^. The Ibises. 



The Ibises are long-necked, long-legged, and small-bodied 

 birds, resembling Herons in habits. The bill is long, slender, 

 and slightly curved, giving somewhat the appearance of a Curlevv. 

 They seek their food along the borders of lakes, ba3's, marshes, 

 and mud flats.
