At a recent meeting of the Academy of Natural Sciences, Mr. Meehan exhibited a nest of the wood pewee, and remarked that, contrary to the statement of most authors, it was evident that no glutinous material was used by this bird in nest-building, but that the structure was held together and bound to the supporting limb by means of cobwebs. He commented upon the adornment of these nests with lichens, and considered the occurrence and uses in such cases of mere decoration without any apparent utilitarian intent.
