Red-tailed hawk down
An adult female red-tailed hawk was found on highway 177 in Oklahoma in early November. It was presumed that the bird was hit by a car. The hawk was placed on IV fluids and force fed. CBC revealed immature Leucocytozoon stages. Metronidazole, meloxicam, and baytril were administered, but no response to treatment led to euthanasia. Other parasitological findings are listed below. Can you identify the types of parasites recovered from the red-tailed hawk based on the respective morphological characteristics of each?
