Between March 1989 and February 1994, 4 bald eagles ( Haliaeetus leucocephalus ) from various localities in Kansas were examined for coccidia. One (25%) of the bald eagles was found to be passing an undescribed species of Caryospora in its feces. Oocysts of Caryospora hanebrinki n. sp. are ellipsoidal to ovoidal with a bilayered wall and measure 48.1 × 42.1 μm with a shape index of 1.2. A micropyle, oocyst residuum, and polar granule were absent. Sporocysts are spheroidal, 24.8 μm wide. Stieda, substieda, and parastieda bodies were absent; a spheroidal sporocyst residuum is present; it measures 17.5 μm and is composed of many intact homogenous globules with a few dispersed in a loose spiral around the sporocysts. This is the first caryosporan documented from the bald eagle and is the largest known Caryospora from raptors.
1989年3月至1994年2月期间，对来自堪萨斯州不同地区的4只白头海雕（Haliaeetus leucocephalus）进行了球虫检查。发现其中1只（25%）白头海雕粪便中排出一种未描述过的卡氏孢子虫物种。新种哈内布林基卡氏孢子虫（Caryospora hanebrinki n. sp.）的卵囊呈椭圆形至卵圆形，具双层壁，大小为48.1×42.1μm，形状指数为1.2。无微孔、卵囊残体和极粒。孢子囊呈球形，宽24.8μm。无斯氏体、亚斯氏体和副斯氏体；有球形孢子囊残体；其大小为17.5μm，由许多完整的同质小球组成，少数分散在孢子囊周围呈松散螺旋状。这是首次在白头海雕中记录到的卡氏孢子虫，也是已知来自猛禽的最大的卡氏孢子虫。
