LAND BIRDS. 615 
county, by Jerome Trombley, of Petersburg; from the neighborhood of 
Detroit by Walter C. Wood; from Ann Arbor and Ypsilanti, Washtenaw 
county, by A. B. Covert, Norman A. Wood, Robert H. Wolcott, and Dr. 
Van Fossen of Ypsilanti, and from Kalamazoo by Dr. Morris Gibbs and 
several of his friends. It undoubtedly breeds wherever it is found in 
Michigan, but, inhabiting as it does the upper branches of the tallest trees 
of the bottom lands, mainly sycamores, its nest is not easily found, and 
although the birds have been seen several times constructing nests (twice 
in Monroe county and once in Kalamazoo county), the eggs, so far as we 
can learn, have never yet been taken. Mr. Trombley reported the birds 
as common near Petersburg, Monroe county, in the Raisin River valley, 
in 1884, when they first appeared on April 20 and became common on 
April 30. The following year they were first noted on April 20 and again 
on the 29th and on May first. In 1886 two were seen April 17 and another 
April 18, and they became common April 25. The following year they 
were observed in about the same numbers and at about the same time, 
but in 1888, although observed April 20, 21 and 25, Mr. Trombley says 
they were not common. In 1890 he was sure that two or three pairs 
bred along the Raisin River near there, but during succeeding years they 
grew less abundant, until in 1897 he called them rare, and since that time 
but few have been seen. In 1905 Mr. Trombley told us personally that 
he had never taken the nest of this species, but that he once saw a pair 
building a nest and watched them for several days in succession, but the 
nest was on one of the highest branches of a very tall tree and was absolutely 
inaccessible. He finally shot the male in order to positively identify 
the subspecies and the nest was never finished. The trees in that vicinity 
have all been cut now. 
Dr. Gibbs informed us (1905) that one nest was found, probably in the 
year 1876, near Kalamazoo, in a sycamore, near the tip of a small branch 
at least seventy feet from the ground. It was impossible to reach the 
nest, and no eggs have ever been taken in that vicinity. He took a male 
at Kalamazoo May 10, 1877, and other specimens were taken by George 
B. Sudworth, May 6, 1876 and May 8, 1877. Another specimen was 
received from a friend who captured it in a grocery store in IXalamazoo, 
September 21, 1878. Dr. Gibbs also informed us that W. H. Collins of 
Detroit wrote him that he had one specimen, taken there [Detroit] May 
10, 1879, and another taken September 15, 1880. Mr. Walter C. Wood 
secured a pair near Detroit in July 1899 and feels sure that they were 
breeding there (B. H. Swales). Mr. Norman A. Wood of Ann Arbor tells 
us that there is a mounted specimen of this subspecies in the collection 
of Dr. Van Fossen of Ypsilanti which was taken near that place, and 
writes, under date of May 29, 1906, ‘I have found a small colony of the 
Sycamore Warbler along the Huron River within four miles of Ann Arbor. 
I secured a fine pair to mount for the Museum. The first one was seen 
April 22 and a male was taken on the 25th. On May 4a female was taken 
and others seen, and still others were observed on May 6. These birds 
were feeding in a grove of trees, one-half of which were sycamores, and 
they seemed to avoid the other trees and feed only in the tops of the tallest 
sycamores, where I saw them gleaning food from all the limbs, going over 
them very carefully, especially on the under side. In action they resembled 
the Black and White Creeper, and the song as well reminds one of this 
bird only it is much louder and in a higher key.” 
All observers agree that this species is partial to syeamores and in Mich-
