Luis Felipe Baptista:
Maestro of the Avian Symphony

Peter Marler

Any Renaissance man would have good reason to be envious of Luis Felipe Baptista. The amazing breadth of his knowledge, and the range of his cultural, linguistic, and scientific skills may have been equaled, but he was unique in the way in which his many talents, rather than flowing in separate streams, all merged in one creative torrent.

While browsing again through some of his writings, I came across a 1998 article he wrote for Revista Macau, a forum for historical records and reminiscences about life and culture in the former Portuguese colony. Baptista spent the first 20 years of his life there and in nearby Hong Kong.

In this archival spirit, Baptista wanted to record his reflections on the dialect of Portuguese spoken there, and to present a sampling of his experiences as a precocious observer of Asia’s natural history. The cultural focus of the article shows in its euphonious title, “Chivit, Bico-chumbo, and other Pastro-Pastro Macaista” (“The white eye, spice finch, and other birds of Macao”). In it, Baptista recounts his observations on a dozen birds he was especially familiar with as a schoolboy. He describes their habits and voices, and records their names in the Macaista dialect of Portuguese (just one of the five languages in which he was fluent, often eloquent, and some would say even loquacious).

Baptista seamlessly interweaves these ornithological recollections with a brief professional autobiography seasoned with reflections on the ancient Chinese art of aviculture. Again and again he returns to the music of birds, a lifelong fascination he traces back to a pair of budgies and a strawberry finch that his brother gave him as a Christmas gift when he was eight. He learned to imitate the birds by fluttering his lips and blowing through his teeth, doing well enough to persuade a pet canary to copy him.

With its delicate spectacles and endearing song, the chivit was a favorite of serious bird enthusiasts in Macao. These pampered pets were kept in a handmade Ching dynasty cage, with porcelain feeding cups and a tiny vase supplied with fresh flowers each day. As a treat, especially privileged birds were given a peeled water chestnut spiked on a Mai Tai Chaap, a tiny steel fork clipped outside the cage. The fork was mounted on an ivory base carved in the shape of a cicada—the symbol of longevity—or maybe a crab, or a butterfly.

Baptista recalls the ease with which a chivit could be taught the song of another favored pet bird, the green singing finch (Serinus mozambicus). While still a schoolboy, Baptista realized that birds learned their songs by imitation. The theme was destined to become a major focus of his professional life as an expert on animal behavior and world authority on bird song. The experience of raising birds sensitized his ear to the nuances of their songs and taught him many of the avicultural skills that served him so well later in life as a serious student of bird behavior.

Chinese school friends initiated him into other ornithological mysteries, such as the pastor-tira-sorte, or fortune-telling bird (Padda oryzivora), which can foretell the future. For a fee, the bird’s keeper opens the door of its tiny cage. The bird presumably subjects the customer to close scrutiny, hops to a small box full of numbered sticks, and pulls one out. The fortuneteller lets the bird take a grain of unhusked rice as its reward before it returns to the cage. The fortuneteller then matches the number on the stick with a numbered index card and reads the customer his or her fortune.

Another favorite songster of old Macao, garbed in the black hood and white cassock of a Dominican friar, was the Dominico, or magpie robin (Copsychus saularis). Besides enjoying their songs, the Macaista also staged fights for them and bet on the outcome in a teahouse that Baptista frequented as a boy. Baptista describes how they are left to fight until one retreats and crouches motionless in submission while the other loudly proclaims victory. Baptista’s anecdotes leave us in no doubt that a childhood immersed in Chinese culture helped to endow the future ornithologist with a deep love of birds.

In 1961, at the age of 20, Baptista emigrated to California to attend university; the state remained his home for the rest of his life. He took degrees at the University of San Francisco and the University of California at Berkeley, where he acquired what was to be a lifelong fascination with the song of the white-crowned sparrow, Zenotrichia leucophrys. Audible everywhere on the Berkeley campus, this bird would become the subject of more than half of the 120 or so scientific papers Baptista would publish. Common in Bay Area parks and gardens, the white-crown was already known to be the supreme example of learned local dialects in North American bird songs, but no one had made more than a casual effort to describe exactly how their songs varied from place to place.

In an amazing tour de force, Baptista mapped these songs in exquisite detail from California to British Columbia. Armed with a tape recorder, headphones, and his slightly intimidating, parabola-mounted microphone, he toured tirelessly up and down the West Coast in an old Mercedes, constantly alert for new song patterns, and infuriating other drivers by screeching to a halt at the slightest avian sound, blissfully unaware of the traffic jams he created.

He showed that boundaries between dialects are sometimes sharp, but often fuzzy, and that birds may be bilingual at the interface. Using his acutely sensitive ear and remarkable memory, he was able to infer where birds singing during autumn migration had originated, and that they uttered songs which locals then later adopted. This became the classical work on bird song dialects.

Baptista traveled the world to study song and call dialects of birds. As a fellow of the elite Max Planck Institute for Behavioral Physiology in Bavaria for a couple of years, Baptista turned his attention to the chaffinch (Fringilla coelebs). The outcome was probably the most thorough study ever of geographical variation in a bird call, as opposed to song. Baptista toured southwest Germany recording and analyzing nearly 3,500 of the male chaffinch’s “rain calls,” so-called because this low-level alarm call sometimes heralds an approaching storm. He showed how the variants are distributed as local dialects, in much the same way as in the male song. He went on to study the vocal behavior of birds in many other parts of the world, including the Caribbean, Costa Rica, and New Guinea.

The California Academy of Sciences in San Francisco was Baptista’s home base for the last 20 years of his life. He grew to know practically every resident white-crowned sparrow in Golden Gate Park personally, and was full of anecdotes about them. A close colleague once described him as the Henry Higgins of the bird world. “Luis could stand in the park, hear a call, and declare that ‘the white-crown had a Canadian father and a California mother. It has half an Alberta accent and half a Monterey accent. The parents probably met at the Tioga Pass near Yosemite.’” He did some remarkable experiments on the responses of white-crowned sparrows to different song dialects.

Luis Baptista's efforts were crucial to the keeping alive the plan to restore the Socorro dove (Zenaida graysoni) to its native island off the coast of Mexico.

Baptista demonstrated that, although male white-crowns learn best when young, the timing of song learning is to some extent malleable, especially if older males are exposed to strong social stimulation. Building on his youthful experiences with caged birds, he was the first to find examples of wild birds not known to be habitual mimics that occasionally learned the songs of other species.

This important finding showed that birds’ preferences for learning the songs of their own species is not necessarily a consequence of a physical inability to sing the songs of others. Instead it reflects a bird’s ability to recognize its own species’ song before it starts to sing itself.

Perhaps the most compelling example of his prowess as an aviculturalist was his demonstration in hand-reared Anna’s hummingbirds that song is learned. Their tiny, delicate babies are among the most difficult of birds to raise.

Later in life, Baptista became deeply involved in the conservation of bird populations, especially the 300 or more species of doves that live in all parts of the world. He will be especially remembered for the ongoing effort, using captive-bred birds, to reinstate the Socorro dove on its native island home off the coast of Mexico, where it was extirpated some 20 years ago. Baptista became an authority on doves, and coauthored a major monograph on them for the encyclopedic Handbook of Birds of the World with colleague Pepper Trail and longtime companion Helen Horblit. Horblit and Baptista presided over a household that often overflowed with birds of all kinds, to say nothing of the succulents, cacti, and cycads on which Baptista was also an expert.

Baptista, on a pilgrimage to Charles Dawin's home at Down House, England, contemplates a bust of the great biologist.

Throughout his life, Baptista’s omnivorous appetite for knowledge never abated. He appreciated classical music and was participating in a National Academy of Sciences project on the biology of music and its relationship to bird song at the time of his death. He was also contemplating a radically new edition of his comprehensive textbook The Life of Birds, coauthored originally with the late Joel Welty. This scholar’s goldmine has already served a generation of ornithologists, including young, aspiring initiates and their elders in need of intellectual refreshment.

Above all, Luis Baptista was unstintingly generous with his knowledge. On his office door, he posted a quote from Thomas Jefferson: “You are here to enrich the lives of others,” a commitment he honored in full.

Reminiscences of Luis

For Luis

Michael McClure

Experience can be said to have inspired the linnet divinely

but the song is born from the deep lyric’s grammar

located in flesh inside of the head.

When the meat and fluff drops away and the beak is clean

of the touch of the tongue then the home of the song is gone

though it still is heard in the forest. To chant,

the troubador must hear the voice of an elder

master. That makes the light that brightens

the depths of the skull. Flutterings transmute

to concertos and garbled chatter changes

to warblings—the plain blank field

becomes verdure. Pensive, the white-turbaned sparrow is listening

but it hears no music when the towhee calls.

It’s meaningless background to him. The core of the music is childless

if it has no listener—then it’s strange as another planet.

 

Specimen Days with Luis Baptista

Pepper Trail

I had the good fortune to spend many days in the field with Luis. Of course, for Luis “the field” encompassed any outdoor locality with a singing white-crowned sparrow, and so included every patch of greenery in San Francisco. One memorable spring evening, Luis and I headed into Chinatown for dinner. As we emerged from the parking garage underneath Portsmouth Square, Luis stopped abruptly. Holding up a finger, he urged me to concentrate until, finally, I detected, between the sounds of traffic and the cries of children drifting over the rooftops, the thin whistle of a white-crown. After much scanning, we located the bird, perched on a restaurant’s skewed TV antenna. There was certainly no other white-crown within hearing, but this wandering bird had found the most appreciative audience in the world: Luis, grinning from ear to ear, standing at the borderline between East and West, lost in the beauty of this evening serenade.

Luis astounded many visitors with his encyclopedic knowledge of the sparrows of Golden Gate Park. Every spring, he dragged nonplused millionaire donors and bemused world-famous scholars outside to regale them with tales of avian divorce, duplicity, and dynastic struggle in the hedges around the Academy. For several years I also studied the white-crowns of the park. Every afternoon I would walk into the Birds and Mammals Department and report the results of the morning’s field work. Luis often knew the identities of the birds I was studying before I did (it could take days to get a good look at their color-band combinations), and unfailingly rattled off their genealogy and the details of their songs. I can’t count the number of times when he sent me to a distant corner of the park to search for a particular pair, and there they were.

I traveled to a more exotic locale with Luis only once, for our study of the St. Lucia black finch. This mysterious bird had often been mentioned as a possible relative of Darwin’s finches, but its behavior had never been studied. As we bounced along the nominal roads that hugged the steep cliffs of this Caribbean island in our rented jeep, Luis endangered our lives with his hilariously fractured renditions of reggae songs.

The project was a great success: we found an active nest and made the first field study of the black finch, confirming many similarities between the St. Lucia black finch (genus Melanospiza), Darwin’s finches, and the grassquits (genus Tiaris), as Luis had predicted.

One night near the end of the trip, we were camped at a remote cove on the arid east side of the island. This was a sea turtle nesting beach, and we had been asked by local biologists to count any turtles that came ashore. We awoke after midnight to stumble along the beach, the faint moonlight just bright enough to reveal the weird shapes of the cacti and agaves in the darkness. Suddenly, we came upon a gigantic form looming up from the sand: a leatherback turtle laying her eggs. Uncharacteristically speechless, Luis kneeled down and stroked the strangely soft back of the turtle. But he could never be close to an animal for long without speaking to it, and soon Luis was crooning to the mother leatherback in his quiet, melodic, sing-song way. For over an hour, the only sounds were the gentle crashing of the surf, the sighs of the laboring turtle, and Luis’s encouraging voice.

Luis had many special qualities, but perhaps they came down to this: he was a profoundly encouraging soul. By his generosity, his intelligence, his curiosity, and his boundless love of life, he encouraged everyone who knew him. It is hard to imagine a better legacy.

 

In Search Of Pigeons

Helen Horblit

It was supposed to be a couple of hours’ drive according to the distance on the map, but we didn’t count on the roundabouts, and it took more than five hours to drive to the end of England—Land’s End. We went not to see the smugglers’ caves, but to see the place where wild rock doves lived, living as ‘pigeons’ were supposed to at the sea’s edge nesting on small ledges above the treacherous waves. The larks ascending from the bluffs behind us were a bonus and inspired Luis to whistle Vaughn Williams’s imitation of the birds.

Afterward, we barreled halfway back across England to Down House, Darwin’s residence, a point of pilgrimage for island biologists. Luis wanted to look at Darwin’s stuffed pigeons. He had been there earlier in the year with his friend Clive Catchpole, and Luis guiltily related how they had taken turns jumping the velvet rope in Darwin’s study as the other grown biologist acted as lookout in case the caretaker came. They sat behind Darwin’s desk in Darwin’s chair just long enough for evolutionary inspiration to flow.

We arrived after tea, walked the paths where Darwin walked, and headed for the study. Luis and Clive had been so excited about their trespass that they never noticed the video security camera pointed at the desk to catch the pious. We retreated to the parlor where the glass cases containing the pigeons stood. With a look perhaps of recognition, the caretaker allowed Luis to hop the velvet rope for a closer look at the pigeons, still brilliant after more than 100 years. Luis recognized all the breeds and I heard him murmur, “So that’s where he was going.”

 

My Friend, Louie

Bob Drewes

Louie was consumed and driven by his passions. I remember a function at Pepperwood Ranch, the Academy’s nature reserve, where the curators were present to interpret the wonders of the landscape for visitors. Although I was the reptile and amphibian expert, I quickly learned that if Louie found a frog or lizard or snake before I did, an immediate lecture on the critter would ensue from him. And it would be every bit as deep and precise as I would have delivered. I watched the botanists and the entomologists learn the same lesson that day. The depth of his knowledge was staggering. And whoever was standing next to him got the benefit. It was not really lecturing or teaching that Louie did, it was sharing.

In 1999, Louie traveled to the Bohemian Grove with me to give a “Museum Talk.” To a first-time visitor, the Grove can be a very intimidating place. To a first-time speaker, the prospect of lecturing to a crowd of over 400 men, many of whom are among the most powerful in the country, can be daunting. Louie was as eloquent, confident, and powerful as I ever heard him. At the conclusion, many men came down to the podium and kept him there for questions. The last and most persistent three included the president of a university, a world authority on hearing loss, and the director of a well-known acoustics laboratory.

Later, Louie and I were invited to a place called Pelican Camp for lunch. Pelicans is a somewhat formal camp whose membership includes the likes of Walter Alvarez and Richard Muller, both world-class scientists at Berkeley, a political scientist or two, and a famous musician. Guests are frequently tapped to speak extemporaneously. Louie got the nod and proceeded to regale us with marvelous anecdotes about pelicans. After lunch a group of guest musicians played the works of an obscure Venezuelan composer named Astor Piazzolla, who wrote tangos for the accordion. No one else at our end of the table had ever heard of him, so we were astounded to learn that Louie not only knew the works of Piazzolla, but his personal history as well. And, when the group finished, Louie got up, walked over and embraced one of the older musicians who, it turned out, had, years ago, played music with his uncle. I remember being warmed beyond my ability to describe.

 

In the Field

Sandra Gaunt

For those of us who worked with Luis in the field, his talent as a raconteur took on a whole different color. He was always animated during the telling of a story, and he often couldn’t talk, gesticulate, and walk at the same time. This was the case one particular day in Reserva Biológica Hitoy Cerere in Costa Rica. Luis, a colleague, and I were fording a rather fast tributary of the Rio Estrella. It was shallow in only a narrow stretch that forced us to walk no more than two abreast. Each of us was loaded down with equipment—binoculars, recorders, microphones, parabolic reflector—and supplies, and trying not to get anything wet. Luis was in front, talking a mile a minute when, in the swiftest section, in order to expand the animation that accompanied his story, he stopped dead. I am afraid I became quite impatient.

That evening, as we walked back to the camp, I stopped to examine what I thought was a small frog and was quite puzzled when Luis piped up, without really being close enough to see what I was looking at... or so I thought. “That’s a toad bug,” he said. Sure enough, I found it later in Study of Insects by Borror, DeLong and Triplehorn—Gelastocoris oculatus—a toad bug! What a day!

 

Reminiscences of Luis Baptista

Barbara B. DeWolfe

Luis loved to tell how he transformed his Ph.D. qualifying oral exam: “When I entered the room I saw six grim-looking men sitting stiffly upright around the table. Their first question to me was: ‘Do you know an example of parthenogenesis in vertebrates?’ “‘You mean the Virgin Mary?’ I replied. After that, everyone relaxed.”

A daughter of actor Jimmy Stewart visited Luis one day and said she would like to work for him. “Just a rich, spoiled kid,” Luis told me he thought, but he took her outside the Academy to show her where he was observing white-crowned sparrows. As they stood talking, a gull flew overhead and deposited its droppings on Judy’s head. “When the gull shit on her, she never even flinched,” Luis said. “I knew then she would make a good field assistant.” (She did.)

Luis was appointed Head of Birds and Mammals at the California Academy of Sciences in part to effect a more frequent and favorable rapport with the visiting public. He was superbly successful at this. Once when Luis was telling a general audience about his research, his infectious enthusiasm inspired one elderly lady to ask Luis to give her a wish list of things he needed for his research. Luis wrote her a letter, telling her in detail his goals and the equipment he would need. She replied: “I don’t understand one word of your letter, but please use these stock certificates to buy whatever you want.”
