Figure 4. Seasonal changes in the isotopic composition of carbon and deuterium in the tissues and body water of white-winged doves. Note that deuterium and d13C increase concurrently at the peak of saguaro fruit use. Doves use saguaro as a source of both nutrients (as revealed by d13C) and water (as revealed by dD). Points are means and bars are standard errors. Numbers in parentheses are sample sizes.
