Serum collected from 68 thick-billed parrots (Rhynchopsitta pachyrhyncha) from 15 institutions was analyzed for ionized Ca (iCa), total Ca (tCa), P, total protein (TP), albumin (Alb), parathyroid hormone (PTH), and vitamin D3. Values were not distributed normally; 95% frequency intervals were as follows: iCa (0.82–1.3 mmol/L), tCa (1.37–2.09 mmol/L,), P (0.35–1.75 mmol/L), TP (21–39 g/L), Alb (9–13 g/L), PTH (0–65.68 pmol/L), and vitamin D3 (5.2–51 nmol/L). Sixty percent (±7.5%) of tCa was ionized. Female thick-billed parrots had significantly higher mean iCa (1.11 mmol/L, n = 22) than male thick-billed parrots (1.05 mmol/L, n = 32). tCa and iCa values in thick-billed parrots were lower than the reported values for other psittacine species. A significant positive linear relationship existed between Alb–TP and iCa–tCa ratios. A significant inverse linear relationship was also identified between the tCa–P ratio and PTH. These findings are consistent with known domestic avian Ca physiology.
