CHAPTER 1
The Reluctant Ewe
For ten years I'd been tending a small flock of sheep on seven acres in a town in Westchester, New York, and I had seen enough lambs being born that I thought I knew exactly what to expect. I took certain things for granted. The lamb, black and glistening, eyes closed and seemingly lifeless, as it slipped out of the ewe. The ewe's quick interest in her offspring, the wet heap in the hay beneath her. Her methodical licking of it to life. She clears the nose and mouth of mucus and dries the head to prevent loss of heat from that vulnerable part. Then she works back over the entire body, speaking to the lamb all the while with gurgling, low -pitched bleats, to which the lamb soon responds with its own, weak-at -first, high-pitched "Maaaa."
The lamb begins to wriggle about, and, in a half hour or even less, it tries to get up. The ewe may knock it down again with her vigorous licking. She may even try to hold it down with a foot. But eventually the lamb succeeds and begins its search for the teat. It is guided by smell and a few simple rules or instincts. Move toward any large object. Place your head under any projecting surface. Once in contact with an object, thrust upwards with your head, munching and sucking on anything that touches your mouth. The ewe does not assist the lamb in this quest, but her tendency to turn and lick it as it moves toward her (the only large object around) eventually brings the lamb in contact with her udder. There it munches and sucks on everything it encounters until it finally finds what it's looking for.
This is what I had come to expect. It didn't seem to matter whether the ewe was an experienced mother delivering her third set of twins or a maternal neophyte faced with her first lamb. The umbilical cord would break as the lamb dropped to the ground, but it would be immediately replaced by a tether just as strong, a tether made of senses — smell, taste, sight, touch, and sound — a tether that binds ewe and lamb together and synchronizes their behavior, that locks them into a tight two-step in which the needs of the lamb and the caregiving of the ewe are perfectly matched.
Last April, though, one of my yearling ewes delivered a healthy male lamb and turned all these expectations inside out.
I had never intended to breed this yearling ewe. "Children should not have children," I've said, probably much too often, to my own two girls, and I've tried to apply this principle to life in the sheep shed as well. The ewe had been born in March of the previous year, which meant that she was sexually mature in September but that she would not reach her full adult size for some time. Last November, however, when the ram we rented from an upstate sheep farmer was doggedly pursuing all of our ewes as they came into estrus, the yearling, who had been kept in a separate pen, somehow got free. By January we realized that the ram had had his way with her too.
I had already had one unusual delivery that day when the yearling delivered. A three-year-old ewe had given birth to twins — a male lamb weighing twelve pounds and a female, only four. The ewe lamb looked more like a rat, and I had visited mother and lambs often during the day to make sure she was nursing — even to the point of holding her twin brother back. The rationing appeared to be working, and that afternoon when I brought grain down for all the sheep, the pint-sized female was already catching up.
The sheep gathered at the trough as usual, butting one another to get a better position, eating quickly and noisily. The yearling was there, unaware, it seemed, of the two dark hooves protruding from her backside. Twenty minutes later, a nose was visible; twenty minutes more, a head. No longer was the yearling unaware. Now she pawed the ground, gasping and blowing through her nostrils. She lay down, chewed her cud, then rose, heavy and awkward, to paw the ground some more.
I sat on a log some fifteen feet away, waiting for the lamb to drop out so that I could treat the broken umbilical cord with iodine, then pen the two together. Thus, I was watching when, with a heavy grunt from the yearling, the lamb dropped to the ground. I was watching when, instead of turning to investigate her offspring, instead of smelling the lamb and licking the lamb, talking to the lamb and listening to the lamb, the ewe simply and quickly walked away. Without a moment's hesitation. Without a backward glance. She cared, it seemed, as much for the creature lying there on the damp ground as for one of her innumerable daily droppings. I felt as if I was watching the ovine equivalent of a teenage mother, with an unwanted, unplanned pregnancy, placing her newborn in a trash container before she headed off to school. And, of course, I was.
I picked up the lamb and hurried after the ewe, shoving the lamb under her nose to encourage her to begin licking it, knowing that if this relationship didn't take I would soon have a very time-consuming bottle lamb on my hands. She turned away and ran off, trailing the placenta behind her. I thought of all the methods that shepherds have of encouraging a ewe to adopt an orphan lamb: rubbing the orphan with afterbirth or squirting it with kerosene or the mother's milk or the ruse that Gabriel Oak and Bathsheba had used in Far from the Madding Crowd, draping the skin of the ewe's dead lamb over the orphan's back. But this was different. This was a mother rejecting her own lamb.
Perhaps I could appeal to even more basic instincts, I thought, and hurried inside to get a loaf of bread, which I then rubbed all over the lamb. If the ewe ate the bread — one of a sheep's favorite foods — she would be tricked into imbibing the birth fluids and, possibly, into behaving like the mother she was. I caught the ewe and penned her and her bread-encrusted offspring, but she couldn't have been less interested. The lamb played his part beautifully, bleating softly, trying to right himself, but the ewe only pawed at the gate to get out. If she wasn't pawing at the gate, she was butting at her son.
It was one of the first really warm days that we'd had, but despite the temperature outside, the lamb's mouth was growing cold. It needed to nurse. Lambs that do not stand and nurse within the first hour have a very poor chance of surviving. I tied up the ewe and held the lamb to her udder. He was quick to catch on and suckled for almost half an hour, then fell immediately to sleep. I went down to the sheep shed two more times that night and had to tie the ewe up each time so the lamb could nurse. I hoped to see some spark of a growing attachment but saw instead a furious ewe, desperate to be let out.
The next morning I didn't know what I'd find. I was surprised at how quiet the shed was as I walked toward it. No angrily baaing ewe. No hungrily bleating lamb. Had the lamb died and the ewe broken out? No, there they were, the lamb nursing vigorously, tail wagging; the ewe standing still and allowing this most ordinary, most extraordinary of things to take place. At one point, the ewe looked as if she might turn and butt the lamb, then, at the last moment, the butt turned into a normal maternal tail-sniffing motion. She still wasn't talking to the lamb — she didn't answer his bleats with her baas — but by the end of the day that too came. The following day, I was able to let them out in the field, knowing that ewe and lamb were tethered (far more effectively than when I had the ewe tied up in the shed), and I could now relax.
Or could I? Something about that ewe, so totally lacking in everything that it would take to ensure the survival of her lamb, made me realize that I had been taking much for granted. What is this thing that we call maternal instinct? Is it instinctive? If so, why does it sometimes fail? This ewe, of course, was not the first animal mother to have walked away from her young, nor would she be the last. Lionesses are known for abandoning (or eating) their first litters; bears that have lost one cub often leave the second to starve. Birds abandon their nests under a variety of conditions. But why? Are these animals simply making mistakes? Are these the bad parents of the animal world? Or is something else going on? In the case of my yearling ewe, was she too immature to care for her lamb? But what would that mean? That she lacked the appropriate hormonal or physiological machinery? If that were so, then one night's penning wouldn't have solved the problem. No, it wasn't a lack of mother's milk that had kept the ewe from accepting her lamb. It wasn't the ewe's hormones or her physiology that was off but her parental behavior, behavior that was every bit as important to the lamb's survival as the mother's ability to mate and bear healthy young.
I didn't realize it at the time, but my unmaternal ewe had opened a small door for me into the natural world, and I — as a science writer, a part-time shepherd, a mother — was inclined to go through it and look for the answers to these questions and to the others that ensued.
Why do some animals care for their young while others bear them and then leave them to their fate? In those animals that do care, why do some rely on mothers to raise the offspring and others, fathers? Or fathers and mothers? Why is parenting a lifelong job for some animals and temporary employment for others? What, if anything, can we learn from the startling array of parental behaviors in other animals about being a human parent — a father or a mother — or about what it takes to be a good parent?
As I delved deeper and deeper into parental care, I realized that it was no coincidence that I should have seen that small door, opened, and entered it. I had been circling this subject for a long time as I struggled with the legacy of a family in which long-lasting marriages were rarer than hen's teeth and parents often put their needs ahead of whatever children they had brought into the world. Long, unexplained absences of both my parents had left their mark on me, and when it came time to have children of my own, parenting had not come easily. Sensitivity had not been high on the list of my family's most valued character traits; plus, I was filled with the dogma of the seventies, the idea that children should not interfere with one's career. Mindlessly, I headed off to my office on the day I returned from the hospital. But my daughters gradually brought me around. They, who had never learned to conceal their hurts, taught me how to mother them. They schooled me in sensitivity until, finally, I began to find that terra firma that some people are born knowing and others are raised on.
So it was a door into my past that the ewe opened, but it was also, I soon discovered, a very public door, a door that many scientists had entered in the last two decades, asking similar questions and discovering startling things about parental behavior. Ever since researchers laid out a theoretical framework for parental behavior in the early 1970s, ever since it became possible, with DNA fingerprinting, to determine the exact relationships of offspring and the adults that care for them, this has been one of the richest and most productive areas of biological research, casting endless amounts of light on the origins and evolution of parental care, and yielding such peculiar observations as the fact that the dominant females in a baboon troop almost always give birth to girls, that some animals — flamingos and bottle-nosed dolphins, for example — form day-care centers for their young, that some insects care for their young for at least three years and sometimes five.
In the end, I would find answers to my questions about my yearling ewe, but I would also find that my simple views of parents and maternal instinct had been turned upside down and inside out. I would learn a great deal more about the two-step that most ewes and lambs perform perfectly from birth to weaning, but I would also learn about our human two-step (or should it be called a three-step, since it is danced by father, mother, and child?), so different in form, tempo, and duration.
The door would take me away from my home: to bat caves in Mexico and Texas, to the New York Aquarium to observe the maternal behavior of beluga whales, to the Bird House at the Bronx Zoo to watch the hornbills, but, most of all, deep into my own backyard, where bluebirds, finches, starlings, white-tailed deer, paper wasps, bees, sheep, moles, mice, chipmunks, rabbits, and squirrels were all busy preparing and caring for their young, each in their own way — all extraordinary ways of being a parent.
CHAPTER 2Parenting Across the Biological Spectrum
One fall, long after the first killing frost but before the ground had frozen solid, I asked Tom Meyer, the bluebird guru in the town where I live, to help me put up some bluebird boxes. Tom, who advises people about their financial investments when he is not counseling them about bluebirds, brought over two. One was made by Beresford Proctor, a woodworker and retired banker from Mamaroneck, New York, who built more than three thousand bluebird boxes before he died in 1994; the other, a box with much less of a provenance, from Vermont. Both were simple redwood affairs. Both provided ventilation at the top and drainage at the bottom, and both lacked perches so as to discourage perching birds like the house sparrow. Both had holes exactly one and a half inches in diameter — wide enough that bluebirds could fly in and out without damaging their wings but not wide enough for starlings, the bluebird's chief competitor for nesting sites and all-round nemesis. But for a reason known only to bluebirds, Tom said, the birds seem to prefer the boxes from Vermont.
As Tom and I walked around my property looking for the right place to site the boxes, he told me what bluebirds look for in the way of a home and a neighborhood: a southeasterly exposure, so that their eggs and nestlings will get the benefit of the early-morning sun; rolling, open terrain with sparse ground cover where they can find insects; nearby trees in which they can perch and from which they can observe the box and flutter down to the ground to seize a passing spider or caterpillar. This "dropping" technique cannot be practiced just anywhere, for it requires that the birds be able to see the ground from their normal perching height of seven to thirty feet. But compared with the "hopping" technique of the American robin, for example, it is an energetically inexpensive way to feed.
I also learned why the bluebirds are so dependent upon these boxes for their survival. When Shakespeare had Hotspur proclaim in Henry IV, "Nay, I'll have a starling shall be taught to speak nothing but 'Mortimer,'" he could not have imagined the effect this little speech would have on North American songbirds — and particularly the bluebird. At the end of the nineteenth century, the American Acclimatization Society was founded with the goal of establishing in the United States every species of bird mentioned by the great bard. The European starling throve in its new environment, and this once-welcome guest now always wins out in competitions with the bluebird for natural nesting cavities — in trees, fences, or houses. Between 1957 and 1967, the year when ornithologists came to realize that, as long as there are starlings in America, bluebird boxes are the bluebirds' only hope, the population of eastern bluebirds was reported to have declined by over 80 percent.
But starlings are not the only reason for the bluebird's decline. Another is far more subtle and goes back thousands of years. The bluebird, with its innate preference for cleared spaces surrounded by woodlands, is the perfect settlement bird. It benefited from the opening of the eastern forest, from agriculture and all that agriculture brought with it: clearing, lumbering, fencing, orchards, pastures.
The bluebird's fortunes soared when American Indians and then Europeans began farming the Northeast, and, by the 1800s, it was one of the most common dooryard birds, frequenting almost every orchard and grove, nesting in hollow stumps and fence posts. But its fortunes fell just as fast when farms gave way to suburbs and fields to lawns, especially lawns sprayed with pesticides. Today in the Northeast, bluebirds are rare enough to be something of a status symbol, and Tom says he is always getting calls from cross homeowners asking why the So-and-Sos have bluebirds in their box and they don't. He doesn't mind, he says, as long as it means that people are putting up boxes.
Given the bluebird's preference in habitat, it wasn't surprising that Tom chose to site the boxes he had brought over in the fields where my husband and I pasture our sheep. Not only did these fields have the closely shorn, well-lit areas that bluebirds like but the edges of the fields were a tangle of bittersweet, sumac, chokecherries, and honeysuckle, vines and shrubs that my husband and I had never gotten round to clearing. Come spring, all these plants would still have some of last year's fruits on them, dried fruits that could tide the bluebirds over while they waited for the first insects to hatch. All would also bear new fruits in the summer, and during the hot months of July and August, the bluebird parents could feed berries to their nestlings to keep them from becoming dehydrated.
