The parasitemias are significantly lower in adult compared with juvenile house sparrows. The infection intensity (log 10 parasitemia, box plot where the bottom and top of the box indicates the first and third quartiles, the central line corresponds to the median, the whiskers represent the highest and lowest value within 1.5 * the interquartile range respectively) in adult and juvenile house sparrows blood positive with H. passeris (green) and P. relictum (blue) from July until October 2016 (week 30–43, N = 19 adult and N = 11 juvenile house sparrows)
