106. Chordeils virginianus virginianus, Nighthawk. There must be 
days or evening's when this species passes over in numbers, but we have 
never been here then, nor have we dates that indicate nesting, but a 
few pair probably do. May 20, 1916, I found a dead one along the 
railway track between Gary and Millers, which seemed to have flown 
against a wire, an unusual thing for such an accomplished flier. ; 
107. Chaetura pelagica, Chimney Swift. Cannot be called common 
here in the usual meaning of that word as applied to Chimney Swifts. 
A pair or two are seen around the farm buildings of the region and a 
few more in the village of Millers. They arrive during the last week 
in April and are gone by the end of August, with a few ga 
flying over in September. 
These last two species seem to me to be extending their fall migra- 
tion farther into autumn every year. 
108. Archilochus colubris, Ruby-throated Hummingbird. This is the 
only member of the order that can be called common, even if only 
locally so. What comes near to being a nesting colony of them was 
discovered by Mr. Stoddard and Mr. Richardson along the creek at 
Tremont, where they found nine nests within a rather small radius. 
We also found an old nest in Mineral Springs, 25 feet up in a black 
birch, 10 feet out on a limb. 
ORDER PASSERES: Perching Birds. 
109. Tyrannus tyrannus, Kingbird. A moderately common breeder, 
but abundant on certain days in migration. Thus on August 13, 1915, 
on a walk from Gary to Millers, it seemed to be the most prominent 
bird. On the other hand, May 20, 1916, we saw only two at Mineral 
Springs. 
110. Myiarchus crinitus, Crested Flycatcher. For this species the 
Dunes and adjacent swampy woods are a metropolis. Stoddard found 
several pairs nesting where the B. & O. Railroad passes through such 
woods near Millers, June 21, 1914. May 20, 1916, we saw about twelve 
at Mineral Springs, and August 3, 1915, about four at Millers; May 30, 
1916, five at Mineral Springs. 
111. Sayornis phoebe, Phoebe. A few pair only breed in the Dunes. 
March 30, 1916, Stoddard must have struck a migrating flight of them, 
for he saw twelve near Millers; April 1, along the Calumet from Gary 
to Millers, we saw only two, one singing or twittering ecstatically in 
flight, which I never saw a Phoebe do before. 
112. Nuttallornis borealis, Olive-sided Flycatcher. Rather common 
in migration from the middle of August to the first week in September, 
between and on the dunes just back from the lake. August 23, 1916, 
Stoddard took four at Mineral Springs, and saw a number of them 
August 30 near Millers.
