Richardson, who spends more time in the Dunes than anybody I know 
of, saw three at Mineral Springs, June 17, 1917. 
89. Falco columbarius columbarius, Pigeon Hawk. Probably not as 
rare as supposed. We saw one at Mineral Springs, March 11, 1916. 
90. Falco sparverius sparverius, Sparrow Hawk. Rather rare here. 
I saw one at Millers, September 29, 1915. 
The Osprey can hardly fail to at least pass over our region at times, 
but I have no recent dates. Mr. Stoddard and I saw one near Kouts, 
Porter County, just a few miles south of the Dunes, May 6, 1916. 
91. Asio wilsonianus, Long-eared Owl. Apparently a rare migrant 
and breeder, but is perhaps only more secretive than rare. Stoddard 
has seen several at Mineral Springs, and found a nest of them with 
three partly feathered young, May 25, 1914. 
92. Asio flammeus, Short-eared Owl. Should be common here, as the 
swales that attract the Marsh Hawk are equally attractive to it, but it 
is not. It must nest, as adults were frequently seen during May and 
June, 1914, at Mineral Springs. 
93. Cryptoglaux acadica acadica, Saw-whet Owl. Probably a rare 
permanent resident, as witness these dates: Mr. Stoddard took one 
February 15, 1914, at Millers, and one April 4, 1915, at Mineral Springs. 
94. Otus asio asio, Screech Owl. Like the Sparrow Hawk, this is 
not as common as one would expect. It is, of course, a permanent 
resident. We saw one near Millers on March 18th and on August 30th, 
1916. 
95. Bubo virginianus virginianus, Great Horned Owl. Contrary to 
expectations, this species is commoner here than the Screech Owl or 
Short-eared Owl seem to be. In a walk between the dunes from Millers 
to Mineral Springs, three or four may be scared up, and there is a pair 
staying in the dark tamarack and pine swamp at the latter place, and 
another one nearby. We saw three, e.g., March 11th and 18th, 1916; 
August 30, we saw one near Millers being pestered by crows. Stoddard 
has found three nests in one season alone, to which were added three 
or four more near to Dune Park or Mineral Springs the following sea- 
sons. Here are nesting data: March 15, 1914, a nest was found with 
three slightly incubated eggs in a scrub pine, forty feet up; March 17th, 
two eggs were found in the cavity at the top of a large dead pine stub. 
The third, containing three downy young, in a similar location, was 
found April 4th. February 25, 1917, a nest with two eggs was found 
near Dune Park, thirty feet up in a pine, in an old crow’s nest. March 
4th there were three eggs, which are now in my collection. February 24, 
1918, one was found in the same neighborhood, probably built by the 
same pair, containing two eggs, in a Banksian Pine, of which fine photo- 
graphs were secured by Mr. W. D. Richardson, who succeeded in taking
