Henslow’s Sparrow is one of the less common sparrows in Michigan 
and seems to be confined to the southern parts of the state. So far as we 
can learn it was first taken in the state by James B. Purdy, who found the 
nest with eggs at Plymouth, Wayne county, July 27, 1893 (Auk, XIV, 
1897, 220). The nest was destroyed and the eggs broken by a mowing 
machine, but the bird was identified by Dr. C. W. Richmond of the National 
Museum, and enough of the eggs remained for identification by Captain 
Bendire. The following year (1894) a nest and eggs were taken in Jackson 
county, near Manchester, by L. Whitney Watkins, and the writer, accom- 
panied by Mr. Watkins, took a second nest with four eggs at the same 
place June 6, 1904. Under date of June 11, 1908, Mr. B. H. Swales writes: 
“Henslow’s Sparrow seems to be not uncommon in small colonies all over 
Wayne, St. Clair, and Oakland counties, as Taverner, Wood and myself 
have ascertained. I have found a number on Grosse Isle without special 
search.” The bird has also been found in some numbers in Wayne county 
by J. Claire Wood and P. A. Taverner, and by Taverner and Swales near 
Pearl Beach and elsewhere in the southern part of St. Clair county. Speci- 
mens were taken also on June 26, 1907, by E. R. Kalmbach and H. A. 
Moorman, near Eaton Rapids, Eaton county, where a colony was located 
and evidently nesting, although no nests were found. 
There are several records from western Ontario and it seems to be not 
uncommon on both sides of Lake St. Clair. It is by no means an easy bird 
to find, since it frequents wet grounds, often overgrown with long grass, 
weeds and shrubs, and it runs like a mouse among the thick herbage, flies 
rapidly and irregularly when flushed and is usually difficult to start a 
second time. 
The nest is placed on the ground, and the two nests found in Jackson 
county were in very wet situations, the water being ankle deep at the time 
they were taken. The one recorded by Mr. Purdy was in mowing land 
and in a dryer situation. The nest is composed mainly of grasses, coarse 
externally and much finer within, is deeply hollowed and rather carefully 
hidden among the roots of the coarse grasses and weeds. The eggs, com- 
monly four, are bluish white, flecked and speckled with reddish-brown, 
and, like those of the Grasshopper Sparrow, resemble some of the warblers, 
for example, the Maryland Yellowthroat, more than those of other sparrows. 
They average .74 by .57 inches. 
The male has a rapid insect-like trill or song which is sometimes delivered 
while perched in plain sight on the top of a weed-stalk, or in a rosebush or
