: The Birds of the Sand Dunes. Zo 
131. Lowia curvirostra minor, Crossbill. 
132. Lowia lewcoptera, White-winged Crossbill. These two erratic 
northern visitants were reported as numerous for Lake County during 
the summer of 1869 and during the following winter, as quoted by Mr. 
Butler. They still turn up every winter, mostly the former, at Beach, 
near Waukegan, north of Chicago, and it is unthinkable that they would 
not also visit the extensive stands of conifers at the south end of the 
lake. 
133. Acanthis hornemanni exilipes, Hoary Redpoll. On December 
23, 1916, Mr. Stoddard noticed among the numerous redpolls, then in 
the tamarack swamp at Mineral Springs, a small flock of larger and 
whiter ones than linaria. He secured one, which proved to be this form; 
the rest took flight and never showed themselves again. 
134. Acanthis linaria linaria, Redpoll. March 11, 1916, there were 
hundreds in the swamp at Mineral Springs. By November 25th of the 
same year they were back again and were seen December 23, January 6, 
1917, on which days about five hundred were here. By March 24th they 
had dwindled down to about fifteen, at least that is all we saw. They 
fed on the seeds of black birch and alder. They were abundant in many 
places around Chicago that winter. 
There is every likelihood that the other forms of Acanthis linaria 
turn up here at times, as they have done at Chicago, but there is no 
one here to register it. 
135. Astragalinus tristis tristis, Goldfinch. A common summer resi- 
dent, and some flocks stay over winter. April 24, 1915, they: were com- 
mon at Tremont; May 30th, about fifty at Mineral Springs; also July 
18th; August 13th, families of old and young could be seen; August 30, 
1916, on the other hand, I saw only one at Millers. 
136. Passer domesticus, English Sparrow. This pest is here, too. 
137. Spinus pinus, Pine Siskin. An irregularly abundant migrant. 
October 12, 1919, a flock of about 500 were at Mineral Springs. 
188. Plectrophenax nivalis, Snow Bunting. An irregular migrant 
and winter visitant. Sometimes arrives about the middle of October, in 
other years later. Stoddard took three October 28, 1916, near Tremont; 
October 24, 1915, January 6 and February 17, 1917, a little ficck was 
on the beach near Mineral Springs. They are always on the beach, not 
among the Dunes. 
139. Calearius lapponicus lapponicus, Lapland Longspur. Not com- 
mon. March 18, 1916, we saw a flock of about twenty at Dune Park, 
where the dunes have been removed and a large, level, weed-grown area 
is now found instead. 
140. Pooecetes gramineus gramineus, Vesper Sparrow. A few breed 
here; they are found from March 30th (1916) to October 28th (1916).
