Bay, and would probably come south on the west side of Lake Michigan, 
while these coming southwest in fall along the coast from Michigan 
should be the eastern form, Chen hyperboreus nivalis. 
37. Chen caeruiescens, Blue Goose. Mr. Stoddard saw a flock of 
about forty off Gary, October 21, 1916, one of which, a fine male, he 
collected. He concludes that this species is probably common for a few 
days in fall along the southern end of the lake. 
38. Branta canadensis canadensis, Canada Goose. This species not 
so long ago bred in the Calumet marshes, adjacent to our area, and is 
now a common migrant and winter resident. March 18, 1916, a flock 
of about forty were holding a sort of convention, apparently, at the 
edge of the ice, off Millers, where they were very noisy, as though 
debating hard. April 1, a flock of twelve flew northward, later a flock 
of thirty came in wedge formation, then formed a broad line front, and 
then suddenly, as if by command, broke and plunged down on the lake. 
39. Olor columbianus, Whistling Swan. Mr. Woodruff reports see- 
ing several specimens that had been taken at Liverpool, Lake County, 
and he himself shot one near Hyde Lake in Indiana. It no doubt still 
flies over our region in its migration. 
ORDER HERODIONES: Storks, Herons, Ibises. 
40. Botaurus lentiginosus, Bittern. A common summer resident. 
April 24, 1916, I heard two “pumping” at Mineral Springs. 
41. Ixobrychus exilis, Least Bittern. A common summer resident in 
the fringe of cat-tail around most ponds, especially at Long Lake, where 
I scared up one September 25, 1915. Stoddard found a nest under con- 
struction there June 2, 1916. 
42. Ardea herodias, Great Blue Heron. A migrant of diminishing 
numbers, and a few pairs may still breed along the Calumet, as they 
formerly did in considerable numbers. I saw one August 13, 1915, at 
Millers. 
43. Butorides virescens virescens, Green Heron. A rather common 
summer resident. They like to place their nests in button bush (Cepha- 
lanthus occidentalis) and other growth forming dense masses, and this 
is found along the edge of sloughs in abundance. April 24, 1916, we 
saw one at Dune Park, also June 24. 
44. Nycticorax nycticorax naevius, Black-crowned Night Heron. 
While we have not seen or taken this species lately in the Dunes, it is 
rather common in the whole neighborhood, e. g., Hyde Lake, Kouts, etc., 
so it cannot fail to at least visit the region occasionally. 
45. Grus mexicana, Sandhill Crane. Mr. Stoddard saw three near 
Dune Park, April 7, 1917. He is familiar with the species from a resi- 
dence of years in Florida. They have lately been reported from a num-
