Using microsurgical techniques spinal "gaps" were made in the thoracic level of chick embryos at two days of incubation by removing small lengths of neural tissue. These same embryos were then examined in detail between 17 days and hatching for any behavioral modifications. The frequency and patter

โฆ Synopsis
The right wing of chick embryos, stages 17-18, was extirpated with a view to study the effect of the absence of the right wing on prehatching motility and hatching behavior. Half of the embryos which survived, hatched normally. Detailed observations on these embryos showed that they followed the typical sequence of behaviorial events from day 17 until hatching. The types of behavior patterns were strikingly similar to embryos with both wings intact. A comparison of the qualitative aspects of prehatching behavior showed an increase of head movements in embryos without the right wing.
