Next I sought the testimony of professional ornithologists; and here my worst suspicions seemed in a fair way to be confirmed, although the greater number of my correspondents were unhappily compelled to plead a want of knowledge. Dr. A. K. Fisher had found, as he believed, not less than twenty-five nests, and to the best of his recollection had never seen a male bird near one of them after it was completed. He had watched the female feeding her young, and, when the nests contained eggs, had waited for hours on purpose to secure the male, but always without result.

Mr. William Brewster wrote: "I have found, or seen in situ, twelve hummers' nests, all in Massachusetts. Of these I took nine, after watching each a short time, probably not more than an hour or two in any case. Of the remaining three, I visited one three or four times at various hours of the day, another only twice, the third but once. Two of the three contained young when found. The third was supposed to have young, also, but could not be examined without danger to its contents. I have never seen a male hummer anywhere near a nest, either before or after the eggs were laid, but, as you will gather from the above brief data, my experience has not been extensive; and in the old days, when most of my nests were found, the methods of close watching now in vogue were unthought of. In the light of the testimony to which you refer, I should conclude, with you, that the male hummer must occasionally assist in the care of the young, but I am very sure that this is not usually, if indeed often, the case."

Mr. H. W. Henshaw reported a similar experience. He had found four nests of the ruby-throat, but had seen no male about any of them after nidification was begun. "I confess," he says, "that I had never thought of his absence as being other than accidental, and hence have never made any observations directly upon the point; so that my testimony is of comparatively little value. In at least one instance, when the female was building her nest, I remember to have seen the male fly with her and perch near by, while she was shaping the nest, and then fly off with her after more material. I don't like to believe that the little villain leaves the entire task of nidification to his better half (we may well call her better, if he does); but my memory is a blank so far as testimony affirmative of his devotion is concerned." Mr. Henshaw recalls an experience with a nest of the [Rivoli humming-bird (Eugenes fulgens)], in Arizona,—a nest which he spent two hours in getting. "I was particularly anxious to secure the male, but did not obtain a glimpse of him, and I remember thinking that it was very strange." He adds that Mr. C. W. Richmond has told him of finding a nest and taking the eggs without seeing the father bird, and sums up his own view of the matter thus:—

"Had any one asked me offhand, 'Does the male hummer help the female feed the young?' I am quite sure I should have answered, 'Of course he does.' As the case now stands, however, I am inclined to believe him a depraved wretch."

Up to this point the testimony of my correspondents had been unanimous, but the unanimity was broken by Dr. C. Hart Merriam, who remembers that on one occasion his attention was called to a nest (it proved to contain a set of fresh eggs) by the flying of both its owners about his head; and by Mr. W. A. Jeffries, who in one case saw the father bird in the vicinity of a nest occupied by young ones, although he did not see him feed or visit them. This nest, Mr. Jeffries says, was one of five which he has found. In the four other instances no male birds were observed, notwithstanding three of the nests were taken,—a tragedy which might be expected to bring the father of the family upon the scene, if he were anywhere within call.

In view of the foregoing evidence, it appears to me reasonably certain that the male ruby-throat, as a rule, takes no considerable part in the care of eggs and young. The testimony covers not less than fifty nests. Some of them were watched assiduously, nearly all were examined, and the greater part were actually taken; yet of the fifty or more male proprietors, only two were seen; and concerning these exceptions, it is to be noticed that in one case the eggs were just laid, and in the other, while the hungry nestlings must have kept the mother bird extremely busy, her mate was not observed to do anything in the way of lightening her labors.

As against this preponderance of negative testimony, and in corroboration of Mr. Lowell's and Mrs. Treat's circumstantial narratives, there remain to be mentioned the fact communicated to me by Mr. Hoar, that a townsman of his had at different times had two hummers' nests in his grounds, the male owners of which were constant in their attentions, and the following very interesting and surprising story received from Mr. C. C. Darwin, of Washington, through the kindness of Mr. Henshaw. Some years ago, as it appears, a pair of ruby-throats built a nest within a few feet of Mr. Darwin's window and a little below it, so that they could be watched without fear of disturbing them. He remembers perfectly that the male fed the female during the entire period of incubation, "pumping the food down her throat." All this time, so far as could be discovered, the mother did not once leave the nest (in wonderful contrast with my bird of a year ago), and of course the father was never seen to take her place. Mr. Darwin cannot say that the male ever fed the young ones, but is positive that he was frequently about the nest after they were hatched. While they were still too young to fly, a gardener, in pruning the tree, sawed off the limb on which the nest was built. Mr. Darwin's mother rescued the little ones and fed them with sweetened water, and on her son's return at night the branch was fixed in place again, as best it could be, by means of wires. Meanwhile the old birds had disappeared, having given up their children for lost; and it was not until the third day that they came back,—by chance, perhaps, or out of affection for the spot. At once they resumed the care of their offspring, who by this time, it is safe to say, had become more or less surfeited with sugar and water, and gladly returned to a diet of spiders and other such spicy and hearty comestibles.

Mr. Henshaw, with an evident satisfaction which does him honor, remarks upon the foregoing story as proving that, whatever may be true of male hummers in general, there are at least some faithful Benedicts among them. For myself, indeed, as I have already said, I hold no brief against the ruby-throat, and, notwithstanding the seemingly unfavorable result of my investigation into his habits as a husband and father, it is by no means clear to me that we must call him hard names. Before doing that, we ought to know not only that he stays away from his wife and children, but why he stays away; whether he is really a shirk, or absents himself unselfishly and for their better protection, at the risk of being misunderstood and traduced. My object in this paper is to raise that question about him, rather than to blacken his character; in a word, to call attention to him, not as a reprobate, but as a mystery. To that end I return to the story of my own observations.

In last month's article [13] I set forth somewhat in detail (if the adverb seem inappropriate, as I fear it will, I can only commend it to the reader's mercy) the closeness of our watch upon the nest there described. For more than a month it was under the eye of one or other of two men almost from morning till night. We did not once detect the presence of the father, and yet I shall never feel absolutely sure that he did not one day pay us a visit. I mention the circumstance for what it may be worth, and because, whatever its import, it was at least a lively spectacle. It occurred upon this wise: On the 19th of July, the day when the first of the young birds bade good-by to its cradle, I had gone into the house, leaving my fellow-observer in the orchard, with a charge to call me if anything noteworthy should happen. I was hardly seated before he whistled loudly, and I hastened out again. Another hummer had been there, he said, and the mother had been chasing him (or her) about in a frantic manner; and even while we were talking, the scene was reënacted. The stranger had returned, and the two birds were shooting hither and thither through the trees, the widow squeaking and spreading her tail at a prodigious rate. The new-comer did not alight (it couldn't), and there was no determining its sex. It may have been the recreant husband and father, unable longer to deny himself a look at his bairns,—who knows? Or it may have been some bachelor or widower who had come a-wooing. One thing is certain,—husband, lover, or inquisitive stranger, he had no encouragement to come again.
