SOME RARE INDIANA BIRDS. 
Amos W. But Ler. Indianapolis, Indiana. 
The birds of Indiana are not the same they were when we were young. 
They are continually changing. Of course there are certain species that 
remain somewhat stationary, but for the most part there are changes. 
1. Those that are decreasing in numbers (water-fowl) or have entirely 
disappeared (Parakeet, Pigeon, Raven, Turkey). 
2. Those that are increasing in numbers (Most meadow forms, spar- 
rows, ete.). 
3. Those that are extending their range (Bobolink, Bachman’s Spar- 
row, Bewick’s Wren, Mockingbird). 
4. Those of (a) accidental, (b) rare, or (c) unusual occurrence : 
(a) Brunnich’s Guillemot, Man-O-War Bird, Brown Pelican. 
(b) Snowy Owl. 
(ec) Bohemian Waxwing, Evening Grosbeak. 
Added to these transpiring changes is the ever recurring one of inspiring 
interest, which we call migration. So to the student of birds there are 
countless changes and numberless surprises in his observations from year 
to year. 
A few observations of special interest are noted here in order that they 
may be known and preserved. 
The least known part of Indiana is that neighboring Lake Michigan. 
Only in recent years have experienced observers been giving attention to 
that area and from them we are receiving some of our most valuable ree- 
ords of bird distribution and behavior. With the changes that are occurring 
in that region many favorite bird sites are disappearing and with them are 
going the birds. 
The proposed Dune Park, if realized, will be a factor in preserving for 
future generations many species of birds as well as other animals and 
also plants. 
I am indebted to Mr. H. L. Stoddard for many interesting notes from the 
Dune region of Indiana. Of the Lake Michigan neighborhood in Lake and 
Porter counties, unless otherwise noted, the following records are from him: 
HORNED GREBE. Colymbus auritus Linn. Fairly common November 
2, 1919, between Millers and Dune Park, Indiana. November 9, 1919, lit- 
erally hundreds of Horned (and other) Grebes fishing off shore with Loons 
(very numerous) between Mineral Springs and Dune Park, Indiana. 
RING-BILLED GULL. Larus delawarensis Ord. Fairly common be- 
tween Millers and Dune Park, Indiana, August 24. 1919. Very numerous 
at Dune Park, Indiana, August 31, 1919. 
BONAPARTE’S GULL. Larus philadelphia (Ord). Seen by the hun- 
dred on the lake (Michigan) between Millers and Dune Park, Indiana, 
October 26, 1919. Noted also from same territory November 2, 1919. On 
November 9, 1919, between Mineral Springs and Dune Park, Indiana. 
More numerous than I ever saw them before. They sat on the lake in 
white windrows, hundreds to a row. Other hundreds fluttering over the 
water and still others circling high in the air like hawks.
