Polish Investigations on Homing in Birds and Their Orientation in Space

The Factor of Topographical Cues in Bird Homing Experiments

“…Several theories have been advanced to account for the "sense of direction" attributed to homing birds. Among the theories which attracted most attention were · the Coriolis force theory of Ising ( 1946) which was later extended and coupled with the theory of electro-magnetic effects by Yeagley ( 1947) and the infra-red vision theory of Wojtusiak ( 1949). In accordance with many other investigators, e.g.…”

Stimulus control for bird orientation.

“…The coming into home territory seemingly determines the rate of return. In a similar study, Wojtusiak (1949), experimenting with the European tree sparrow Passer montanus, also nonmigratory, found no birds returned home from distances greater than 7 miles. The extraordinary abilities in certain migratory sea birds, have, on the other hand, been demonstrated.…”

“…TRUE NAVIGATION Wojtusiak (1946Wojtusiak ( , 1949, reporting on studies made in Poland, brought forth the theory that birds may be sensitive to the infrared visual spectrum. If the theory holds, birds could see through fog and also at night.…”

Travels and Traditions of Waterfowl

“…This, it is felt, is due largely to the 'puddling' method of feeding which operates probably as much by the sense of touch as by sight." Vanderplank (1934) and Wojtusiak (1949), among others, have presented what they believe to be evidence of avian awareness of infrared.…”

“…With Swallows, Wodzicki and Wojtusiak (Wojtusiak, 1949) found that in many of their experiments "there was noticeable a characteristic behavior of the birds at the moment of their release. The Swallows soared up into the air, described one circle or several, and then started to fly in a direct line toward their nesting site."…”
