136 FIELD MUSEUM OF NATURAL HISTORY 
Case G. — A group of Ducks is shown in a section of a pond 
with the shore line fringed with grass. Some stand on the shore 
and others are swimming about near the edge of the pond, while 
in the background half hidden by the grass, a Florida Lynx 
is seen stealing upon the unsuspecting birds. The species of 
ducks represented are the Pintail, Lesser Scaup and Ring-necked 
Duck. 
Hall 27. 
BIRDS OF ILLINOIS. 
Devoted exclusively to Illinois Birds and their eggs. The 
specimens are arranged by families in vertical sections, beginning 
at the right hand of the entrance from Hall 26, the order of 
classification being that adopted by the American Ornithologists 
Union. 
In the center of the hall is a large group illustrating the nest- 
ing habits of the American Egret, one of the “plume birds.” 
STUDY COLLECTIONS. 
The study collection of Mammals, Fishes, Reptiles and In- 
sects, consisting of thousands of specimens contained in tin, air- 
tight cases and glass jars, is located in the balcony over the 
south entrance, and is accessible during museum hours to those 
who desire to study the material or compare specimens. Every 
attention is paid to this important adjunct to the exhibition 
series for the assistance of scientific investigation. The study 
collection of Birds containing between thirty-five and forty 
thousand specimens is installed in the gallery of Hall 27. The 
Museum also contains study collections of Skeletons, Skulls and 
other Osteological material.
