SUMMARY 1. An account is given of observations on three pairs of marked Fulmars. The young were brooded for very irregular periods, and in one pair the female took the greater share. 2. In the first two to three weeks of the chick's life it does not recognize its parents. and treats them as intruders to be repelled. The parent has a characteristic method of approach with which the chick gradually becomes familiar. 3. A small but distinct territory around the nest‐site is defended by the chick and parent birds. 4. Feeding takes place at any time during the day, but the chick is probably not fed daily during the first week or two. During its first two to three weeks the chick does not show any interest in its parent and has to be stimulated before feeding takes place. When older, the chick is able to recognize its parents and also initiates the feeding process. 5. In four case it was shown that the chick was fed on semi‐digested food material, not oil.
