At this point we suddenly became aware that for at least a day or two

the old bird had probably been feeding her offspring in two

ways,--sometimes by regurgitation, and sometimes by a simple transfer

from beak to beak. The manner of our discovery was somewhat laughable.

The mother perched beside one of the young birds, put her bill into his,

and then apparently fell off the limb head first. We thought she had not

finished, and looked to see her return; but she flew away, and after a

while the truth dawned upon us. Thereafter, unless our observation was

at fault, she used whichever method happened to suit her convenience. If

she found a choice collection of spiders,[12] for instance, she brought

them in her throat (as cedar-birds carry cherries), to save trips; if

she had only one or two, she retained them between her mandibles. It

will be understood, I suppose, that we did not see the food in its

passage from one bird to the other,--human eyesight would hardly be

equal to work of such nicety; but the two bills were put together so

frequently and in so pronounced a manner as to leave us in no practical

uncertainty about what was going on. Neither had I any doubt that the

change was connected in some way with the increasing age of the

fledgelings; yet it is to be said that the two methods continued to be

used interchangeably to the end, and on the 28th, when Number Two had

been out of the nest for seven days, the mother thrust her bill down his

throat, and repeated the operation, just as she had done three weeks

before.

[12] Mr. E. H. Eames reports (in _The Auk_, vol. vii. p. 287) that, on

dissecting a humming-bird, about two days old, he found sixteen young

spiders in its throat, and a pultaceous mass of the same in its stomach.

For at least two days longer, as I believe, the faithful creature

continued her loving ministrations, although I failed to detect her in

the act. Then, on the 1st of August, as I sat on the piazza, I saw her

for the last time. The honeysuckle vine had served her well, and still

bore half a dozen scattered blossoms, as if for her especial benefit.

She hovered before them, one by one, and in another instant was gone.

May the Fates be kind to her, and to her children after her, to the

latest generation! Our intercourse had lasted for eight weeks,--wanting

one day,--and it was fitting that it should end where it had begun, at

the sign of the honeysuckle.

The absence of the father bird for all this time, though I have

mentioned it but casually, was of course a subject of continual remark.

How was it to be explained? My own opinion is, reluctant as I have been

to reach it, that such absence or desertion--by whatever name it may be

called--is the general habit of the male ruby-throat. Upon this point I

shall have some things to say in a subsequent paper.

THE MALE RUBY-THROAT.

"Your fathers, where are they?"--ZECHARIAH i. 5.

While keeping daily watch upon a nest of our common humming-bird, in the

summer of 1890, I was struck with the persistent absence of the head of

the family. As week after week elapsed, this feature of the case excited

more and more remark, and I turned to my out-of-door journal for such

meagre notes as it contained of a similar nest found five years before.

From these it appeared that at that time, also, the father bird was

missing. Could such truancy be habitual with the male ruby-throat? I had

never supposed that any of our land birds were given to behaving in this

ill-mannered, unnatural way, and the matter seemed to call for

investigation.

My first resort was, of course, to books. The language of Wilson and

Audubon is somewhat ambiguous, but may fairly be taken as implying the

male bird's presence throughout the period of nidification. Nuttall

speaks explicitly to the same effect, though with no specification of

the grounds on which his statement is based. The later systematic

biographers--Brewer, Samuels, Minot, and the authors of New England Bird

Life--are silent in respect to the point. Mr. Burroughs, in Wake-Robin,

mentions having found two nests, and gives us to understand that he saw

only the female birds. Mrs. Treat, on the other hand, makes the father a

conspicuous figure about the single nest concerning which she reports.

Mr. James Russell Lowell, too, speaks of watching both parents as they

fed the young ones: "The mother always alighted, while the father as

uniformly remained upon the wing."

So far, then, the evidence was decidedly, not to say decisively, in the

masculine ruby-throat's favor. But while I had no desire to make out a

case against him, and in fact was beginning to feel half ashamed of my

uncomplimentary surmises, I was still greatly impressed with what my own

eyes had seen, or rather had not seen, and thought it worth while to

push the inquiry a little further.

I wrote first to Mr. E. S. Hoar, in whose garden Mr. Brewster had made

the observations cited in my previous article. He replied with great

kindness, and upon the point in question said: "I watched the nest two

or three times a day, from a time before the young were hatched till

they departed; and _now you mention it_, it occurs to me that I never

did see the male, but only the white-breasted female."

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 re-enacted. 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.

[13] These two humming-bird papers were printed in consecutive numbers

of _The Atlantic Monthly_, June and July, 1891.

As if to heighten the dramatic interest of our studies (I come now to

the promised mystery), we had already had the singular good fortune to

find a male humming-bird who seemed to be stationed permanently in a

tall ash-tree, standing by itself in a recent clearing, at a distance of

a mile or more from our widow's orchard. Day after day, for at least a

fortnight (from the 2d to the 15th of July), he remained there. One or

both of us went almost daily to call upon him, and, as far as we could

make out, he seldom absented himself from his post for five minutes

together! What was he doing? At first, in spite of his sex, it was hard

not to believe that his nest was in the tree; and to satisfy himself, my

companion "shinned" it, schoolboy fashion,--a frightful piece of work,

which put me out of breath even to look at it,--while I surveyed the

branches from all sides through an opera-glass. All was without avail.

Nothing was to be seen, and it was as good as certain, the branches

being well separated, and easily overlooked, that there was nothing

there.

Four days later I set out alone, to try my luck with the riddle. As I

entered the clearing, the hummer was seen at his post, and my suspicions

fastened upon a small wild apple-tree, perhaps twenty rods distant. I

went to examine it, and presently the bird followed me. He perched in

its top, but seemed not to be jealous of my proximity, and soon returned

to his customary position; but when I came back to the apple-tree, after

a visit to a clump of oaks at the top of the hill, he again came over. I

could find no sign of a nest, however, nor did the female show herself,

as she pretty confidently might have been expected to do had her nest

been near by. After this I went to the edge of the wood, where I could

keep an eye upon both trees without being myself conspicuous. The

sentinel spent most of his time in the ash, visiting the apple-tree but

once, and then for a few minutes only. I stayed an hour and a half, and

came away no wiser than before. The nest, if nest there was, must be

elsewhere, I believed. But where? And what was the object of the male's

watch?

My curiosity was fully roused. I had never seen or heard of such conduct

on the part of any bird, and the next forenoon I spent another hour and

a half in the clearing. The hummer was at his post, as he always was. We

had never to wait for him. Soon after my arrival he flew to the

apple-tree, the action seeming to have no connection with my presence.

Presently he went back to the ash, and drove out of it two intruding

birds. A moment later two humming-birds were there, and in another

moment they flew away in a direction opposite to the apple-tree. Here,

then, was a real clue. The birds were probably our sentinel and his

mate. I made after them with all speed, pausing under such scattered

trees as had been left standing in that quarter. Nothing was to be

found, and on my return there sat the male, provokingly, at the top of

the apple-tree, whence he soon returned to the ash. A warbler entered

the tree, and after a while ventured upon the branch where the hummer

was sitting. Instead of driving her away he took wing himself, and paid

another visit to the apple-tree,--a visit of perhaps five minutes,--at

the end of which he went back to the ash. Then two kingbirds happened to

alight in the apple-tree. At once the hummer came dashing over and

ordered them off, and in his excitement dropped for a moment into the

leafy top of a birch sapling,--a most unnatural proceeding,--after which

he resumed his station in the ash. What could I make of all this?

Apparently he claimed the ownership of both trees, and yet his nest was

in neither! He sat motionless for five minutes at a time upon certain

dead twigs of the ash, precisely as our female was accustomed to sit in

her apple-tree. For at least seven days he had been thus occupied. Where

was his mate? On the edge of the wood, perhaps. But, if so, why did I

hear nothing from her, as I passed up and down? Again my hour and a half

had been spent to no purpose.

Not yet discouraged, I returned the next morning. For the three quarters

of an hour that I remained, the hummer was not once out of the ash-tree

for five minutes. I am not sure that he left it for five minutes

altogether. As usual, he perched almost without exception on one or

other of two dead limbs, while a similar branch, on the opposite side of

the trunk, he was never seen to touch. A Maryland yellow-throat alighted

on one of his two branches and began to sing, but had repeated his

strain only three or four times before the hummer, who had been absent

for the moment, darted upon him and put him to flight. A little

afterward, a red-eyed vireo alighted on his other favorite perch, and he

showed no resentment. The day before, a warbler had sat on the same

branch which the yellow-throat now invaded, and the hummer not only did

not offer to molest him, but flew away himself. These inconsistencies

made it hard to draw any inference from his behavior. During my whole

stay he did not once go to the apple-tree, although, for want of

anything better to do, I again scrutinized its branches. This time I

_was_ discouraged, and gave over the search. His secret, whatever it

might be, was "too dear for my possessing." But my fellow-observer kept

up his visits, as I have said, and the hummer remained faithful to his

task as late as July 15th, at least.

Some readers may be prompted to ask, as one of my correspondents asked

at the time, whether the mysterious sentry may not have been the mate of

our home bird. I see no ground for such a suspicion. The two places were

at least a mile apart, as I have already mentioned, and woods and hills,

to say nothing of the village, lay between. If he was our bird's mate,

his choice of a picket station was indeed an enigma. He might almost as

well have been on Mount Washington. Nor can I believe that he had any

connection with a nest found two months afterward in a pitch-pine grove

within a quarter of a mile, more or less, of his clearing. It was

undoubtedly a nest of that season, and might have been his for aught I

know, so far as the mere fact of distance was concerned; but here again

an intervening wood must have cut off all visual communication. If his

mate and nest were not within view from his ash-tree perch, what could

be the meaning of his conduct? Without some specific constraining

motive, no bird in his normal condition was likely to stay in one tree

hour after hour, day after day, and week after week, so that one could

never come in sight of it without seeing him. But even if his nest was

in the immediate neighborhood, the closeness and persistency of his

lookout are still, to my mind, an absolute mystery. Our female bird,

whether she had eggs or offspring, made nothing of absenting herself by

the half hour; but this male hardly gave himself time to eat his

necessary food; indeed, I often wondered how he kept himself alive. Is

such a course of action habitual with male hummers? If so, had our

seemingly widowed or deserted mother a husband, who somewhere, unseen by

us, was standing sentry after the same heroic, self-denying fashion?

These and all similar questions I must leave to more fortunate

observers, or postpone to a future summer. Meantime, my judgment as to

the male ruby-throat's character remains in suspense. It is not plain to

me whether we are to call him the worst or the best of husbands.

ROBIN ROOSTS.

"From every side they hurried in,

Rubbing their sleepy eyes."

KEATS.

Of all the nearly eight hundred species of North American birds, the

robin is without question the one most generally known. Its great

commonness and wide distribution have something to do with this fact,

but can hardly be said to account for it altogether. The red-eyed vireo

has almost as extensive a range, and at least in New England is possibly

more numerous; but except among ornithologists it remains a stranger,

even to country-bred people. The robin owes its universal recognition

partly to its size and perfectly distinctive dress, partly to its early

arrival in the spring, but especially to the nature of its nesting and

feeding habits, which bring it constantly under every one's eye.

It would seem impossible, at this late day, to say anything new about

so familiar a bird; but the robin has one interesting and remarkable

habit, to which there is no allusion in any of our systematic

ornithological treatises, so far as I am aware, although many individual

observers must have taken notice of it. I mean the habit of roosting at

night in large flocks, while still on its breeding grounds, and long

before the close of the breeding season.[14]

[14] Mr. William Brewster has been aware of this habit for twenty-five

years, but, like myself, has never seen it mentioned in print. He

devotes to it a paper in _The Auk_ for October, 1890, to which I am

happy to refer readers who may wish a more thorough discussion of the

matter than I have been able to give. My own paper was printed at the

same time, in _The Atlantic Monthly_, and had been accepted by the

editor before I knew of Mr. Brewster's intention to write. References to

a roost in Belmont, Mass., discovered by Mr. Brewster six years before,

are frequent in the following pages.

Toward the end of summer, two years ago, I saw what looked like a daily

passage back and forth of small companies of robins. A friend, living in

another town, had noticed similar occurrences, and more than once we

discussed the subject; agreeing that such movements were probably not

connected in any way with the grand southward migration, which, so far

as we could judge, had not yet commenced, but that the birds must be

flying to and from some nightly resort. The flocks were small, however,

and neither of us suspected the full significance of what we had seen.
