Great Barbet Nesting in Hong Kong

AJP spotted Great Barbets (Psilopogon virens) in the New Territories of Hong Kong last week. They are uncommon residents, living in mature secondary broadleaf forests. They are also difficult to spot in the canopy. He later spotted a nest hole, high in a tree.








The Great Barbet is now only to be found in the New Territories but Herklots in his Hong Kong Birds of 1953 noted that in the early decades of the 20th century they were on Hong Kong island, even nesting in the Botanic Gardens in 1929. Herklots wrote:

I have never seen an adult near the nest; my collectors say that the adult bird comes quickly with a dash, i the usual manner with much noise, to feed its young, stays a few seconds and then dashes away in its normal undulating flight.

You can see the speed at which the adults leave and enter the nest in the short video.




Herklots also noted that the birds were often heard, with the call of the male ‘going on and on’, but seldom seen. ‘This bird never comes to the ground and spends its life in the dense fung shui woods of the valleys’. He regarded the population as a small number of year-round residents augmented by summer visitors.

One of Hong Kong's most impressive birds.

Elke Zimmermann 1958-2019. Herpetologist and Primatologist

Elke Zimmermann
from here

A few weeks ago while working on a different topic I came across the sad news that Elke Zimmermann had died in 2019 at the age of 61. Her book, Breeding Terrarium Animals, the English-language version of which appeared in 1986, drew on the major and then novel  advances being made in Germany on the breeding of amphibians and reptiles. Elke and her father Helmut (b 1926), an architect in Stuttgart, were very much part of the group of German herpetologists at the forefront of breeding tropical frogs and toads. The book was highly influential across the English-speaking world since it was part of a new wave of herpetology—the successful and reliable breeding of amphibians and reptiles in captivity—that was spreading across the world in the 1970s and 80s. The German-language version, Das Zuchten von Terrarienteren, was published in 1983 when Elke was 25. The publisher’s blurb, as this translation shows, makes the point about that new wave:

The breeding of amphibians and reptiles was considered difficult for a long time; almost only accidental breedings were known. Only in recent years has there been increased effort not only to keep these animals in captivity for as long as possible, but also to breed them. In this book, the author describes the reproduction and breeding of more than 300 species of amphibians and reptiles, with a large proportion of the animal species discussed in more detail being bred in the Zimmermann terrariums…


I have not seen the German edition of the book, published in 1983 when Elke Zimmermann was 25,  but the English-language version, published by the notorious Herbert Axelrod (1927-2017) under his TFH company, was said to contain new material as well more photographs, i.e  in the TFH house style.

Father, Helmut, and daughter, Elke, kept an array of animals at home. She became particularly interested in the vocal communication of dart frogs during their complex breeding behaviour. She continued through university and developed her interest in this field, particularly in primates. She went on to work extensively in Madagascar, particularly on the small lemurs, where her father was a leading light in conservation, but had wide interests and established breeding colonies of several species back in Germany, thereby combining field and laboratory studies


From 1996 until her death Elke Zimmermann was Professor in the Institute of Zoology in the University of Veterinary Medicine, Hannover.

To commemorate her life colleagues in primatology contributed to a special issue of International Journal of Primatology which covered her main interests. That volume also offers a glimpse of her early life (references omitted): 

Encouraged by her father, Elke became interested in zoology very early in life. She published her first article when she was 16 years old on an inventory of reptiles, which she had observed during an excursion with her family in Southern Spain. Her first article on primates followed 2 years later, in which, together with her father, she assembled recommendations for the housing of lorises (Nycticebus spp.), squirrel monkeys (Saimiri spp.), and talapoin monkeys (Miopithecus spp. At that time, all these species were housed in her family’s house and garden. She continued to publish on the biology of primates, amphibians, and reptiles while she studied biology at the University of Hohenheim. Although she wrote her dissertation on the neurobiological basis of acoustic communication in frogs and regularly published on amphibians until 1994, primates became her main interest after her PhD and during her career. She was interested in the evolution of primates, but in contrast to most researchers who focused on haplorrhine primates, Elke investigated the roots of the primate order and specialized on strepsirrhine primates…

I only realised years after the event  that in 2003 we had stayed in the accommodation Elke and her colleagues used at Ampijoroa in Madagascar. Then, there was no tourist accommodation (there is now) serving the Ankarafantsika National Park and groups picked up camping equipment at Mahajanga before driving the 70-odd miles to Ampijoroa. When it was discovered that two double rooms at the field station were unoccupied, the two oldest couples were allocated those. Initially thankful for being war babies, we had two uncomfortable nights, not helped by the swarms of mosquitos that danced above the open drains which ran round the entire block. Ampijoroa is an amazing site. A plethora of lemurs, other mammals, birds and reptiles was around every corner. But one species in particular is relevant to this discussion.

One evening on a walk on the lake side of the field station we had definite sightings of a species of mouse lemur only described a few years earlier.  It was the Golden-brown Mouse Lemur, Microcebus ravelobensis, named for Lake Ravelobe at Ampijoroa. Elke Zimmermann was first author of paper which described and named the new species in 1998. Notices warning of crocodiles in Lake Ravelobe have to be taken very seriously. Before our visit the local bird guide had been killed by the Nile Crocodiles found there—a fact not mentioned by the tour companies these days. When we walked along the shore, we saw the screens in the water behind which the local women could still wash the clothes. The danger was so great, we were told, even the men had started to do the washing.

While Elke Zimmermann is remembered by her scientific colleagues for her more recent research on primates, herpetologists will remember her earlier studies on, and breeding of, amphibians and reptiles with fondness and great admiration.

Pallas’s Squirrel on the Peak, Hong Kong

AJP photographed this squirrel on the Peak, Hong Kong island last week. I have written about Pallas’s Squirrel (Callosciurus erythraeus) in Hong Kong before, including its origins as an escapee from the pet trade, and the possibility that some are natural re-introductions from across the border. This one, with the light tip to the tail is typical of the ones found on Hong Kong island. Compare this with one he photographed in the New Territories (here) with the black ‘spot’ in the tip of the tail. The red belly—often not that easy to see from the side—which is not a constant feature, can be seen in this one.

It has been argued that those in the New Territories are the subspecies C. e. styani and those on Hong Kong island are C. e. thai.

Günther's Frogs in Hong Kong. Start of the breeding season

 I have shown photographs of Günther's Frogs (Sylvirana guentheri) before but I could not resist these AJP photographed a few days ago at Tai Po Kau. I do not know why some individuals have the reddish back.

Australian Grass Parakeets: a colour plate from 1952

In the days when colour printing was extremely expensive, the Avicultural Society had special appeals for funds to support the appearance in Avicultural Magazine of the occasional colour plate. A well-known bird artist was then commissioned. Although the whole run of the Society’s magazines can be found online, the plates rarely see the light of day. Therefore I decided to show one, now and again, on this site. This is the 18th in the series.

– – – – – – – – – –



The artist of this plate was Neville William Cayley (1886–1950) well known in Australia for having produced the first full field guide to the birds of that country, What Bird is That ?, in 1931.

The accompanying note was written by Edward Jeffrey Boosey (1902-1969) who proceeded to tear the plate apart:

As is often the case with very prolific painters, however, his work as a bird artist tended to be of uneven quality, and I personally consider the accompanying colour plate one of his less successful efforts, as it cannot be called an accurate portrayal of either of the birds it depicts.

While I should hate to appear in the role of a carping critic, I do think the mistakes in the plate should be pointed out, as there has always appeared to exist a certain amount of confusion in people's minds when it comes to identifying the various species of Grass Parrakeets*….

Edward Jeffrey Boosey (a Boosey of the Boosey & Hawkes, music publishers) was a well known aviculturist. He and Alec Grantham Sagar-Musgrave-Brooksbank MC (1898-1967), known as Alec G. Brooksbank, had established Keston Foreign Bird Farm in Kent in 1927. Parakeets (stupidly now often called just ‘parrots’ by those who decide the common names of birds) and their breeding were a major interest.

Boosey described his experience of the Elegant Parakeet (Neophema elegans):

Elegants are among the most satisfactory of the Grass Parrakeets in confinement. I have kept and bred them regularly for the last sixteen years or so, and they were the only species of Grass Parrakeet we managed to keep going at Keston all through the war. They are also the only member of the Grass Parrakeet family to have become sufficiently well-established in a few people’s aviaries in this country for one to see young ones offered for sale at fairly regular intervals.

He had kept only one pair of Rock Parakeets (Neophila petrophila). Both became obese and produced only infertile eggs.

Judging by photographs online (I have seen neither species in the wild), Boosey was right. But then why did the Avicultural Magazine use the scarce resources available for printing colour plates  publish this plate?

Avicultural Magazine 58, 1952

*’Parrakeet’ was used by Avicultural Magazine but at some time must have changed to the now much more familiar ‘parakeet’.

Miss Waldron's Red Colobus: Any photographs or further information on Fannie Waldron?

 Having started this series with finding out who Miss Waldron was, I shall end it with a request.

I have come across no photographs of Fannie Waldron nor of any that she took, other than the few shown in Willoughby Lowe’s book. Does anybody have photographs or know if they still exist?

Robert William Hayman in his paper which named the monkey for Miss Waldron, states that she retained two skins of the African Golden Cat (now Caracal aurata), one of the grey (from Mampong) and one of the red (from Goaso) colour morphs. I winder what happened to them.

Hayman also saw a Gambian Sun Squirrel (Heliosciurus gambianus) from Pong, Tamale, in the north of what is now Ghana. That was brought back alive and kept by Fannie Waldron. I wonder if anybody who worked for Fannie Waldron left tales of her keeping animals that she brought back?

Finally, having done two collecting trips with Willoughby Lowe why did she not carry on, perhaps attached to another collector? Lowe, as the last chapter covering the 1933-34 and 1934-35 expeditions in his book, The End of the Trail, shows had really reached the end of the trail. Did she try? Or was two a sufficiency?

I just end this series of articles, as so many others, with many unanswered questions.

Miss Waldron’s Red Colobus. Herbert George Flaxman Spurrell: Doctor, Collector, Author, Soldier, Secret Agent

As I showed in a previous article in this series, it was not Willoughby Lowe and Fannie Waldron who brought the first specimens of Miss Waldron’s Red Colobus to the Natural History Museum in London. The two specimens Herbert George Flaxman Spurrell (1877-1918) brought or sent to London in 1912 were recognised as belonging to the same taxon after or while those from the Lowe-Waldron expeditions of 1933-34 and 1934-35 were being examined.

Herbert Spurrell

Spurrell was an interesting character. I get the impression that he was another of those individuals who qualified in medicine but was not that committed to clinical practice, using the profession instead as a passport to being a naturalist in interesting places as well as to cogitate and write on evolution and human behaviour..

Herbert George Flaxman Spurrell was born on 20 June 1877 in Eastbourne, Sussex. His father was an architect in practice in the town. He was educated at Merton College, Oxford, with clinical studies at the London Hospital. He qualified in 1907 with the Oxford MB BCh degrees having already become an Oxford MA. The age of 30 seems very late to qualify, creating the impression that he was not that eager and very much fitting the image of the ‘perpetual student’ doing other things of greater interest. Indeed he wrote two novels (as Herbert Spurrell) after writing one work of non-fiction (see below).

Out of the Past was published Greening & Co in 1903. One reviewer from Eastbourne, the author’s home town was gushing:

The volume consists of three tales of a character so baffling, and dealing with an atmosphere of romance se archaic, that it is difficult—almost impossible—to assign to them a definite classification under any of the ordinary heads of fiction. Yet they are all vivid, full of stirring action, and palpitating with the passions of humanity—which, whether now, or in the neolithic period, have always been, and, we may take it, will alway be, the same…It is impossible to analyse these stories; they must be read and accepted for what they are—paleological romances of a buried age. They are unique, masterly and dramatic; and to fiction readers in search of novelty and excitement we can recommend them with the fullest confidence.

At Sunrise: A story of the Beltane, from the same publisher in 1904. Reviews were mixed:

The author has taken for the scene of his story the wilds of Dartmoor and for period the first century of the Christian era, when England was in the hands of the Romans. The hero is a Britain [sic] prince, who, carried a prisoner to Rome, and has there imbibed some of the civilization of the empire. He contrives to escape, and is brought by a merchant back to his native land. The plot is slight and unostentatious, and turns in the main on the love affairs of a Roman general and a native princess…The author writes in a pleasant and easy manner, knows well how to retain the interest of the reader, and shows considerable descriptive power.


There were no further novels.

In 1901, by which time he had the Oxford BA degree, he was clearly interested in the animal world. The National Archives has a copyright application form from him for a photograph of an Aesculapian Snake—a fitting species for someone pursuing medicine as a career.

The 1909 Medical Register (which would have been compiled in 1908) shows his address as 285 Corfield Street, Bethnal Green in London. Shipping records show he arrived in New Orleans on 24 October 1908 on a ship from Barbados, on which he had earned as passage as the ship’s doctor. He was going to Tulane University where he spent a year as Assistant Professor of Physiology. He was joining the former Oxford don Gustav Mann (1864-1921) who had moved there in the same year as Professor of Physiology. Mann was born in Darjeeling and graduated in medicine from Edinburgh. He moved to Oxford and was remembered thus:

McNalty…says that Mann was a German who lectured in a Teutonic accent, was dark, of middle height with a bushy moustache and thick-lensed spectacles. He was regarded as a wayward genius with an astonishing capacity for work. Mann reduced his diet to maintain his weight at seven stones, allowed himself only four hours of sleep per day and his mattress in the laboratory was an Oxford legend. But as a practical histologist he was regarded as the best of his time.

Mann also worked as an analyst for oil companies but in 1916 resigned from Tulane and went to work as an analyst and doctor in Tampico. Nature published a short obituary after his death in 1921 described his departure from Oxford as a ‘grievous loss to the progress of histology in this country’ but ended with the possible reason:

 …Too volatile to be largely productive in the ordinary way, his "Physiological Histology" is often the most thumbed book in laboratories where section cutting is taken seriously, and many grateful pupils will lament a real master whose determination to get himself disliked led him into so many troublous adventures.

It is not surprising that Spurrell followed Mann to New Orleans. In 1901 Spurrell  had written iwhile still a medical student, his first book, The Commonwealth of Cells, which he dedicated to ‘My esteemed friend and tutor, Gustav Mann MD etc’.

I cannot help but wonder why he did not stay in medical research. Whatever the reason we then find him travelling to and from the Gold Coast (Ghana) from 1909 relatively frequently. He was with his parents, by then living in Exeter, for the 1911 Census on 2 April. It was also in 1911 that his fourth book, Patriotism: A Biological Study (George Bell & Sons, London), was published.

 It was from the Gold Coast that he began taking or possibly sending live animals to London Zoo and dead ones to the Natural History Museum. He was already a Fellow of the Zoological Society. Spurrell’s medical obituarists (and those copying them for Wikipedia) clearly did not understand that such a fellowship was not bestowed by a Society for some worthy deed. The use of the term ‘Fellow’ for ordinary membership has given endless trouble over the years but which probably resulted in subscriptions from London’s wealthy wishing to indulge themselves in the supposed cachet of a postnominal combined with—until the middle of the 20th century—exclusive access to the Zoo on Sundays.

From 1910 until his death, Spurrell recorded his address as the Royal Societies Club, a gentlemen’s club in St James’s, with ‘travelling’ in parentheses. That club continues to be confused online with the Royal Society Club, an entirely different kettle of fish of which this writer happens to be one of the fish. I have not been able to find what sort of medical work Spurrell was doing in the Gold Coast. From the place of collection of animals for the Zoo it would seem that he must have been in Dunkwa for much of the time. In view of his later employment in Colombia, it is possible he worked as a doctor for one of the mining companies. Whatever the nature, Spurrell was awarded the Diploma of the London School of Hygiene and Tropical Medicine in 1912.

Lists of the animals brought back by Spurrell for the Zoo are contained in ZSL’s Annual Reports for 1909, 1910, 1911 and 1912 (see below). For those ‘donations to the collection’ he was awarded the Society’s Silver Medal in 1914, along with three others.

Donations to the Zoo continued when he moved to Colombia in 1912 or 1913 (described in the Annual Reports of 1913 and 1914). There we can find what he was doing. He was based in Andagoya in the Chocó region. He was clearly working as the medical officer for a mining company since that area is a major source of platinum and gold. In a ship’s passenger list he gives as his contact a fried, F. W. Leighton. Frederic William Leighton (1893-1943) can be found in genealogical searches. He was a mining engineer, trained in metallurgy and assaying who was born in Lydiard Tregoze in Wiltshire. He died in Medellín, Colombia but was living in Port of Spain, Trinidad. Leighton had married Bertha Eraerts in 1916.

While in the Gold Cost and Colombia, Spurrell brought or sent hundreds of specimens to the Natural History Museum, concentrating in Colombia on reptiles, amphibians and fish. George Albert Boulenger who worked through the collections and described the new species had a field day.

In October 1913 Boulenger wrote a paper in Proceedings of the Zoological Society describing the first collection brought back from Colombia:

Dr. Spurrell, to whom the Zoological Society is indebted for so many interesting additions to its collection of Reptiles, has now transferred his activity as a collector from West Africa to South America. The series of beautifully preserved Batrachians and Reptiles brought together by him during the first few months of his stay in the Choco, Colombia, and presented by him to the British Museum, is one of great interest and shows how much remains to be done in the exploration of that part of South America.

His job in South America seems to have ended around the end of 1915. He can be found in shipping records leaving Cartagena, Colombia on board the SS Carrillo bound for New York, where he arrived on 4 February 1916. On this manifest are particulars of his height (6’ 1”) complexion (fair), hair (brown) and eyes (grey). He is also recorded as being en route to London.

This is where the story gets more interesting. In his profile for the Royal Army Medical Corps appears the following: 

On his return from Colombia in 1915, Herbert was sent abroad by the Government on a secret mission…

Apart from the fact that his return was in early 1916 and not 1915, I have found no indication of what this secret mission was. However, shipping records show that he returned to New York very quickly after returning to UK on 4 February. He left Liverpool on 18 March 1916 on the Cunard’s Glasgow subsidiary company’s Anchor Line’s SS Tuscania (torpedoed in 1918 by a German submarine with the loss of American troops bound for Europe). This must have been the secret mission but what was he doing? Was it something to do with gold or platinum? Who sent him? What did he achieve?

Because he brought two reptiles back from the USA we know that he must have reached London Zoo by 3 May. Therefore, whatever he did for the government in the USA it happened in April 1916. He may have bought the two reptiles for the Zoo but if he found them, they both occur in and around Texas. Was his mission there? 

On 23 August 1916 he left for Sekondi and the familiar territory of the Gold Coast. His RAMC profile says he was Temporary Medical Officer at Obussi [Obuasi], another major gold mining town. On 1 June 1917 he was commissioned as a Lieutenant in the Royal Army Medical Corps. Spurrell’s final book, back to non-fiction, Modern Man and his Forerunners was published by G. Bell & Sons of London in 1917, a couple of months after joining the RAMC; he had written the book between 1912 and 1916. It was well received in a review in Nature of 6 September but less so, despite agreement with the author on some important points, by the anthropologist, Alfred Cort Haddon, in Eugenics Review who considered some of the arguments on the development of social systems ‘facile’.

Spurrell arrived in Egypt on 23 November 1917. The Royal Air Force was founded on 1 April 1918 and Spurrell is shown as being attached to the RAF, serving on its medical board in Egypt, a function he had presumably undertaken for the Royal Flying Corps. He was promoted to Captain in June 1918 but then died of pneumonia at No 19 General Hospital, Alexandria on 8 November, three days before the Armistice. He was 41. He is buried at Alexandria (Hadra) War Memorial Cemetery.

Herbert Spurrell’s name lives on in a number of eponymous species. The list is shorter than it was in the 1910s and 20s as some have been lumped into other species with priority over the specific name. Examples are Scops spurrelli lumped into Otus icterorhynchus, the Sandy Scops Owl; Graphiurus spurrelli into Graphiurus lorraineus, Lorraine's African Dormouse;  Kinosternon spurrelli into K. leucostomum, the White-lipped Mud Turtle

A number of eponym’s have survived these taxonomic revisions either in the scientific name or the common name. Examples are in the Eponym Dictionary of Mammals, of Reptiles and of Amphibians. Examples are: Spurrell’s Free-tailed Bat, Mops spurrelli; Spurrell’s Woolly Bat, Kerivoula phalaena; Chestnut Long-tongued Bat, Lionycteris spurrelli; Colombian (Butterfly-head) Coral Snake, Micrurus spurrelli; Spurrell’s Worm Lizard, Amphisbaena spurrelli; Spurrell’s Leaf Frog, Agalychnis spurrelli;  Condoto Stubfoot Toad, Atelopus spurrelli.

A fish named for him from West Africa, Fundulopanchax spurrelli (now, it seems, F. walkeri spurrelli), as well as insects, represent some of other specimens Spurrell donated to the Natural History Museum.
