Avian Hematology: Flamingo Blood Cell Morphology

Morphological features of greater flamingo leukocytes and erythrocytes: differentiation of heterophils, eosinophils, and monocytes in avian blood smears.

Flamingo blood smear: heterophil, eosinophil, monocyte, and nucleated erythrocytes

🦩 Blood of a greater flamingo (Phoenicopterus ruber).

The image shows:

  • Heterophil (left) – with a pale basophilic nucleus and brick-red, spindle-shaped cytoplasmic granules.
  • Eosinophil (right) – with a segmented basophilic nucleus and round/oval, brightly eosinophilic granules of various sizes.
  • Monocyte (top) – with a constricted nucleus (reticular chromatin) and agranular basophilic cytoplasm.

Erythrocytes are also visible. Note that the cell shape is distorted due to adjacent elements. (Stain: Modified Wright’s method).
