Body masses of 3,739 birds representing immature and adult males and females of 15 species of passeriforms (both uninfected and infected with Haemoproteus spp. and Leucocytozoon spp.) were compared. There was some interaction among year, month and area of capture for several host species, but there was no discernible effect of either parasite genus on body mass. There were no effects due to high intensity parasitemia for eight host species examined. Either parasitism does not cause loss of body mass, or the techniques used were too insensitive to separate effects of parasitism from other natural causes.
对代表15种雀形目未成熟及成年雄性和雌性鸟类（包括未感染以及感染血变原虫属和白细胞虫属的鸟类）的3739只鸟的体重进行了比较。对于几种宿主物种，捕获年份、月份和地点之间存在一些相互作用，但两种寄生虫属对体重均无明显影响。在所检查的8种宿主物种中，高强度寄生虫血症没有产生影响。要么是寄生虫感染不会导致体重减轻，要么是所使用的技术过于不敏感，无法区分寄生虫感染与其他自然原因的影响。
