1. Femurs taken from Japanese quail (Coturnix coturnix japonica) genetically selected for either exaggerated (HS; high-stress) or reduced (LS; low-stress) blood corticosterone (B) response to unfamiliar environments were examined to determine their cortical bone porosity (CBP; degree of osteoporosis) and medullary bone (MB) status following treatment with or without stress. 2. Femur CBP was elevated in both sexes of stressed, HS-line quail and was attributed directly to the presumably exaggerated blood B responses known to occur in this line as a consequence of the stress treatments used. 3. The increase in CBP in stressed, HS-line birds occurred independently of changes in the numbers of osteoclast cells (CLASTS) associated with cortical bone. 4. Stress treatment was associated with lower CLAST numbers/mm2 of MB and with increased MB accretion. 5. These stress-induced effects were considered to be the consequence of a reduced rate of lay found in stressed quail hens. 6. There was only marginal evidence for a direct effect of B in stimulating MB resorption.
