Claës Christian Olrog

Claës Christian Olrog (born November 25, 1912 in Danderyd , † November 29, 1985 in San Miguel de Tucumán , Argentina ) was a Swedish ornithologist and zoologist who later lived in Argentina. His specialty was ornithology of the Neotropics .

Live and act

His career as a biologist began at Uppsala and Stockholm Universities . Here he studied from 1935 to 1945. At a young age he took part in expeditions to the bird ringing of the Naturhistoriska riksmuseet . His travels took him to northern Scandinavia , Lapland , the Danube Delta , Iceland and Greenland . During his PhD in Stockholm he became interested in South America . A two-year expedition took him from 1939 to 1941 to Tierra del Fuego , the Shetland Islands and Orkney . In 1945 he achieved the degree of doctor. From 1946 to 1947, he and his wife Gunilla Bengt de Olrog went on an ornithological trip to northern and central Paraguay . Here he studied the avifauna of Gran Chaco . On this trip he only moved with the help of very modest means of transport, which included rides on lorries and ox wagons. His wife Gunilla died in Buenos Aires in April 2006 , several years later as Olrog.

Finally, in 1948, he took a position at the Insituto Miguel Lillo of the Universidad Nacional de Tucumánin . Here began a long and arduous struggle for means of developing and researching ornithology on this continent. During the entire time at the Instituto, he maintained contacts with people and organizations outside of South America. He regularly attended international conferences and congresses. In 1983, when he was still old, he attended the Congress of Neotropical Ornithology in Xalapa . One of his friends became François Vuilleumier , who met him in 1965. Vuilleumier called his first major work a funny bird identification book . This comment referred to the relatively poor quality of his drawings. That didn't stop Olrog from criticizing other people's drawings. When Jorge Rodríguez Mata presented him with a picture of the coots for his book Birds of South America for review, Olrog commented on the drawing of the yellow-billed coot ( Fulica armillata ) with the words: The yellow- billed coot of the lakes of Monte y Chascomús consists of one population of mutants .

Another friend became Abraham Willink (1920–1998), who was a curator in the Entomology Department at the Insituto Miguel Lillo . Often under very difficult conditions, he organized field research programs in little-explored areas of Argentina, Bolivia and Brazil . Bird ringing was one of his most important projects. Through his initiative, at least 50,000 birds were ringed with the inscription Deyuelva Instituto Lillo, Tucumán, Argentina so that he could study the migration paths of ducks, geese, herons and other birds. Up until old age he invested a lot of energy in teaching field research and motivated his students to actively practice it. Since the bird ringing was hardly known in Latin America, one can rightly call him a pioneer of field research in this region. For example, in 1975 he visited the province of Formosa with his students Rubén Marcos Barquez , Ricardo Alberto Ojeda and his friend Francisco Contino , a passionate hobby ornithologist and bird artist from San Salvador de Jujuy , to introduce them to research in the great outdoors.

As a result of his in-depth knowledge, over a hundred publications and books in six different languages ​​were created. In some of his publications he collaborated with other authors such as Francisco Contino, Elba Alicia Pescetti , María Magdalena Lucero and Patricia Capllonch . His subjects ranged from general biology, morphology , biogeography , ecology to the systematics of birds, animals and reptiles. In 1959 his first book on the identification of Argentine birds appeared under the name Las Aves Argentinas: una guía de campo . As often in his life, this book could only be published under difficult conditions and through self-financing. In 1984 a modified new edition of the work was published. Other important works by Olrog were Lista y distribución de las aves argentinas from 1963, Nueva lista de la avifauna argentina from 1979 and Guía de los mamíferos argentinos from 1981. In addition to his publications, he wrote on unpublished manuscripts on the birds of Bolivia and a two-volume work on the passerine birds of South America.

Dedication names

In 1978 Daniel Frank Williams (* 1942) and Michael Allen Mares published an article in the Annals of Carnegie Museum with the title A new genus and species of phyllotine rodent (Mammalia: Muridae) from northwestern Argentina , in which they found the Olrogs Chaco mouse ( Andalgalomys olrogi ). In their acknowledgment they write:

“Dr. CC Olrog provided much food for thought on South America's fauna. "

"Dr. CC Olrog gave us a lot of food for thought about the fauna of South America. "

- Daniel F. Williams, Michael Allen Mares : Annals of Carnegie Museum

Manuel Nores and Darío Yzurieta awarded in 1979 in the first description of the two-color bank rocker in their article Una nueva especie y dos nuevas subespecies de aves (passeriformes). / Nidificación del gaviotin Pico Grueso (Gelochelidon Nilotica Gronvoldi Mathews) en Córdoba - Argentina for the Academia Nacional de Ciencias the scientific name Cinclodes olrogi in honor of Olrog. In English, his name can even be found in the common name Olrog's Cinclodes .

The name Olrog also found its way into the common name Olrogmöwe, which he himself was the first to describe in 1958. He described this gull in Acta Zoologica Lilloana in his article Notas ornitotogicas sobre la coleccion del Instituto Muguel Lillo . His name can also be found in other languages ​​in the common name z. B. Olrog's Gull (English), Gaviota de Olrog (Spanish), Goéland d'Olrog (French), Gabbiano di Olrog (Italian), Olrogs Meeuw (Dutch) and Gaivota-de-Olorg ( Portuguese ) .

The Administration of Protected Areas in Buenos Aires was renamed Instituto Claes Olrog in memory of him .
