Remove/treat endoparasites and diseases
A randomised, replicated and controlled experiment in wetlands in Manitoba, Canada (Amundson & Arnold 2010) found that survival of 322 American coot Fulica americana chicks was higher in 2004, when they were treated with fenbendazole (an anthelmintic drug), compared to untreated chicks (51% survival to 40 days for treated chicks vs. 39% for untreated chicks). In 2005, survival of 340 chicks was again increased by treatment, but chicks with parents that were treated whilst incubating also had higher survival rates, despite there being no detectable change in parasite burden in adult birds (58% if both parents and chicks treated; 46% if only chicks treated; 45% if only parents treated vs. 33% if neither treated).
