NOTES FROM THE FIELD. 
LATE CANADA GEESE. 
On April 30th, while working the vast stretch of meadows bordering 
Lake St. Clair, St. Clair County, P. A. Taverner and I saw a flock of some 
large birds alight in the fields some distance away. Upon investigation we 
were somewhat surprised to see a flock of twenty-one Canada Geese feeding 
here. These loomed up very large from amidst the short grass. Upon our 
approach the flock rose in the air and, after considerable circling, went north 
over Dickinson’s Island. Personally I have never seen this species at this 
late date. Generally they do not remain to feed during the spring.

WARBLER DAY. 
May 2nd seems to have been Warbler day in S. E. Michigan this year. See 
N. A. Wood’s account of warblers on that date at Ann Arbor in this issue. 
This same day Mr. B. H. Swales noted an unusual abundance of these birds 
on Belle Isle, Wayne County. Nearly all the birds listed by Mr. Wood were 
present on the island this day, and in very unusual numbers. Apparently 
the crest of a great migration wave struck this vicinity then, and it would be 
interesting to hear how general this movement was and how long it per- 
sisted in its wave-like form. 
AN INTERESTING JUNCO. 
April 30 T took a late Jiuneco near Pearl Beach, st GlainiComaty., ihe 
great mass of this species left here some time ago. The last Junco previous 
was noted April 9. The interest in this bird was heightened upon 
disection, when it proved to be not only abnormally fat, but of no ascertainable 
sex. Birds at this season should be easily sexed, but with a strong magnifying 
glass I could recognize no sexual organs at all. This case indicates the close 
correlation between sexual and migratory instincts, for here we find incom- 
plete sexuality accompanied by incomplete migration. It also shows the 
danger of jumping at conclusions and founding a breeding record on a bird’s 
appearance in an unusual vicinity during the nidification season.
