The birds of the Chicago area /

Abstract

Entry on page 56 reads, "A few are heard, while passing overhead during their migrations, uttering their discordant cries. Mr. B.T. Gault informs me that his observations show that they arrive early in the spring and that the latest record of their return in the fall is August 6. Mr. E.W. Nelson says that it was "once an abundant migrant, but is now of the rare occurrence in this vicinity." Kennicott states that it is now rare, but once not uncommon. The only record I have found of the actual taking of a specimen within our limits is that of Spencer F. Baird who mentions a specimen collected by Thomas E. Blackney who took it at Chicago in June, 1858. This specimen is now at the Smithsonian Institution."
