The Birds of the Sand Dunes. 299 
154. Passerella iliaca iliaca, Fox Sparrow. A common migrant; not 
seen, however, in such numbers as Z. albicollis. April 1, 1916, we saw 
six on the way from Gary to Millers. 
155. Pipilo erythrophthalmus erythrophthalmus, Towhee. This is one 
of the commonest summer residents in this region, from April 1 (1916) 
to late in October. 
156. Cardinalis cardinalis cardinalis, Cardinal. A permanent resi- 
dent, but seen only in a few chosen places. At Mineral Springs and 
Tremont, and especially along the roads leading from there to the beach, 
from one up to a dozen may be seen any day, summer or winter. Novem- 
ber 30, 1918, I saw about fifteen near Millers. 
157. Zamelodia ludoviciana, Rose-breasted Grosbeak. A rare sum- 
mer resident. 
158. Passerina cyanea, Indigo Bunting. A summer resident which 
is somewhat more numerous than the preceding, but cannot be called 
common. 
159. Piranga erythromelas, Scarlet Tanager. A rather rare summer 
resident, something like the Rosebreast in numbers. A little more nu- 
merous in migration. 
160. Progne subis subis, Purple Martin. A summer resident which 
cannot be called plentiful. May 30, 1916, I saw only about six on the 
way from Millers to Mineral Springs, a distance of about twelve miles. 
161. Hirundo erythrogastra, Barn Swallow. A little more numerous 
than the preceding. Both form small colonies about the farm buildings 
on the southern edge of the Dunes. Thus on the walk above referred 
to from Millers to Mineral Springs, I saw about fifteen of this species. 
162. Ividoprocne bicolor, Tree Swallow. During migration many can 
be seen gracefully skimming over Long Lake, but only a few stay to 
nest. On June 19, 1915, I saw a pair at a nesting hole in a dead cotton- 
wood on top of a dune at Millers, and Mr. Stoddard found a nest with 
four fresh eggs in a hole in a telegraph pole near Long Lake, June 
8, 1914. 
The Cliff Swallow will, no doubt, occasionally be found here, too. 
163. Riparia riparia, Bank Swallow. This is the only swallow that 
can be called common, and this only locally. There are several fair-sized 
colonies in precipitous placcs on the first dune from the beach, on the 
side facing the lake, near Millers. July 9, 1915, about three hundred, 
mostly young, were perching on the sand of the beach there or flying 
about aimlessly. 
164. Stelgidopteryx serripennis, Rough-winged Swallow. A rare 
breeder. June 10, 1915, a pair was at the nesting hole in the same 
cottonwood in which the tree swallows were.
