   INTRODUCTION
 
The capacity to mount a cell-mediated immune response in birds is often quantified as the swelling following an injection of phytohaemagglutinin (PHA) into the wing-web. Most studies have found the repeatability of consecutive measurements of the same swelling to be high (e.g., Alonso-Alvarez and Tella, 2001Go; Fargallo et al., 2002Go; Saino et al., 1997Go; Smits et al., 1999Go; Tella et al., 2000Go). However, as pointed out by Siva-Jothy and Ryder (2001)Go, repeatability calculated this way only estimates the precision with which an experimenter measures the size of a particular swelling; it does not encompass other components of measurement error. Furthermore, such estimates of repeatability do not capture temporal variation in individuals' PHA-responses. To our knowledge, no study has reported the latter types . . .
