We test the Murray‐Nolan equation for calculating clutch sizes of birds with demographic data from a long‐term study of the Florida Scrub Jay ( Aphelocoma c. coerulescens ). The predicted value, 3.43, is very close to the observed clutch size, 3.33. This result provides further support for the equation's being an adequate description of the relationship among the factors affecting the clutch size of birds.
