title: Haematological findings in healthy and sick captive rosy flamingos (Phoenicopterus ruber ruber).
abstract: Full blood counts and fibrinogen estimations were carried out on 36 clinically normal adult Rosy flamingos (21 males, 15 females) and six juveniles (sex uncertain). No significant sex differences were found but the haemoglobin levels, red cell counts, packed cell volumes and mean cell haemoglobin concentrations were lower and the white cell counts higher in juveniles than in adults. Reference values obtained from the normal birds were used as a basis for assessing the results of blood counts on nine birds showing a variety of abnormal clinical conditions. Heterophilia occurred in individuals with infections, chronic renal lesions, haemorrhage and suspected thrombosis. In one case, morphologically abnormal heterophils were present. A bird with carcinoma and peritonitis showed heteropenia. Several birds had hypochromic, microcytic red cells and severe hypochromic microcytic anaemia was found in a bird with an organising abdominal haematoma associated with chronic renal pathology. Several of the cases also had thrombocytosis and raised fibrinogen levels.
