Oskar Heinroth — German biologist and pioneer of animal behaviour studies
Oskar Heinroth (1871–1945) was a German biologist whose observations of ducks and geese established species-specific behaviour and helped found ethology; he mentored Konrad Lorenz.
Overview
Oskar Heinroth (born 1 March 1871 in Mainz-Kastel, died 31 May 1945 in Berlin) was a German zoologist and one of the early figures to treat animal behaviour as a subject of systematic scientific study. Working largely with waterfowl, he demonstrated that many patterns of action are characteristic of a species and can be observed reliably under natural and captive conditions. His work helped shift attention from purely anatomical classification to behaviour as a biological trait.

Research and methods
Heinroth combined long-term observation with careful rearing experiments. By raising ducks, geese and related birds from hatching and recording their development, he distinguished innate sequences of behaviour from learned responses. His approach emphasized field-like observation even when animals were kept in captivity, and he paid special attention to the repeatability and species-specific form of actions such as courting, feeding, and parental care.
Imprinting and species-specific behaviour
Among Heinroth's notable contributions was renewed attention to early attachment and learning phenomena in birds. He re-examined earlier accounts of rapid early learning reported in the 19th century and provided systematic evidence that young waterfowl can form strong, lasting attachments shortly after hatching. These findings helped revive study of what later became known as imprinting and clarified that many behavioural patterns are reliably linked to species identity.
Career, influence and legacy
Heinroth served for decades as director of the Berlin zoo and aquarium, where his access to captive animals supported prolonged study. He taught and influenced a new generation of researchers; most notably, Konrad Lorenz regarded Heinroth as a formative mentor and popularised many of the ideas that Heinroth had developed. The emphasis on naturalistic observation and species-specific behaviour contributed directly to the emergence of modern ethology in the 20th century.
Personal life and notable facts
Heinroth's career combined practical animal management with scholarly inquiry. He married twice, both times to colleagues active in zoology: first to Magdalena (née Wiebe) and after her death to Katharina (née Berger). His combination of zoological stewardship at a major European collection and careful behavioural documentation left a lasting impression on how scientists study animal behaviour.

Q: What was Heinroth's contribution to the study of behaviour in ducks and geese?
A: Heinroth's studies of behaviour in the Anatidae (ducks and geese) showed their instinctive behaviour patterns.
Q: What discovery did Heinroth make regarding the behaviour of birds?
A: Heinroth rediscovered the phenomenon of imprinting, which was first reported in the 19th century by Douglas Spalding but not followed up at the time.
