Clean birds following oil spills
A replicated study in Tasmania, Australia (Giese et al. 2000), in the 1995-6 and 1996-7 breeding seasons found that pre-fledging masses of chicks from rehabilitated oiled little penguins Eudyptula minor were significantly lower than those from non-oiled birds (approximately 700-800 g for chicks from 65 pairs with rehabilitated birds vs. 850-900 g for 167 un-oiled pairs). Hatching success did not differ between groups but the number of chicks produced/egg and fledging success were significantly lower among rehabilitated birds in 1995-6, especially for nests that had a rehabilitated female (with 22% lower fledging success), and laying date was also delayed (eggs in nests from early October for un-oiled birds, but first appeared on the 4 November for rehabilitated birds). These differences were not apparent in 1996-7.
