We compared levels of DDE contamination in the eggs of burrowing owls (Athene cunicularia) from the Imperial Valley of California in 2002 to levels detected in eggs collected at the same site in 1996. Levels of DDE ranged from 0.10 to 3.01 µg/g and were similar between years, suggesting a persistent, local source of contaminant for this resident population of owls.
