Changes in the blood and plasma volume of Harris' sparrows during postnuptial molt. 1985

W A deGraw, and M D Kern

In captive Harris' sparrows (Zonotrichia querula), plasma and blood volume increased significantly during stages 2 and 3 of postnuptial molt, when extensive feather replacement was taking place in the wings, tail and body tracts. Erythrocyte number did not increase significantly until molt was essentially complete. Consequently the 6% mean maximum reduction in hematocrit that was observed during molt appeared to be largely the result of plasma volume expansion. This plasma volume expansion was not due to changes in the osmolality or concentration of proteins within the blood plasma since both decreased significantly during intense molt.

D006400	Hematocrit	The volume of packed RED BLOOD CELLS in a blood specimen. The volume is measured by centrifugation in a tube with graduated markings, or with automated blood cell counters. It is an indicator of erythrocyte status in disease. For example, ANEMIA shows a low value; POLYCYTHEMIA, a high value.
