title: On the pattern of organ growth in the common tern (Sterna hirundo).
abstract: Data are presented on the pattern of organ growth in the Common Tern, a semi-precocial bird species with a high growth rate, and are compared with data from some bird species within the altricial-precocial spectrum. The data show that a high growth rate is linked to a growth pattern characterized by a rapid early development of the digestive organs and a late development of pectoral muscles and feathers. These results suggest that the growth rate is most likely restricted by the capacity to ingest and digest food. It also appears that the organ growth pattern is more closely related to the growth rate than to the degree of precocity.
