Comparison of growth rates and fledging weights recorded for thick-billed murre chicks (U. lomyia) by previous investigators shows that these parameters vary widely between studies. Growth rates and fledging weights were measured at 4 colonies in the Hudson Strait area to examine the magnitude of variation both within and among colonies. Significant variations among years and among different areas of a single colony were detected but were less important than colony-specific factors in determining overall variation. A negative correlation between colony size and chick fledging weights suggests that colony size may be an important determinant of intercolony differences.
