HERRERA, J. A et al. HEMATOLOGICAL PARAMETERS OF WILD PARROT CHICKS KEPT IN CAPTIVITY. Rev. Med. Vet. Zoot. [online]. 2013, vol.60, n.2, pp.79-85. ISSN 0120-2952.

The aim of this study, conducted in central Mexico, was to describe the hematological parameters in 69 wild chicks of psittacine kept in captivity, younger than three months of age of four different species: Pionus senilis (n = 18), Amazona albifrons (n = 15), Amazona autumnalis (n = 25) and Amazona oratrix (n = 11). All parrots were sampled to obtaind 500 µl of blood for quantifying hematological parameters. Hematocrit percentage was 56.4 ± 3.36, 51 ± 6.52, 47.6 ± 6.47 and 53.8 ± 9.26; the MCV (fl) was 184.6 ± 13.4, 142.0 ± 25.4, 106.3 ± 11.7 and 162.3 ± 71.9; the erythrocyte count was, 4.7 ± 2.1x10⁶/μl, 6.1 ± 8.2 x10⁶/μl, 6.9 ± 1.2 x10⁶/μl and 5.4 ± 1.1 x10⁶/μl, and leukocyte count was of 3.06 ± 0.15 x10³/µl, 3.62 ± 0.24 x10³/µl, 4.48 ± 0.36 x10³/µl y 3.56 ± 0.71 x10³/µl respectively for P. senilis, A. albifrons, A. autumnalis y A. oratrix. There was a trend to heterophilia in A. oratrix and A. albifrons, which represents a contribution that may be useful for more precise diagnosis in avian clinical practice.
