- Abstract
The biometric parameters of the internal guts that make up the respiratory system of eight Southern Caracara of both sexes, with different weights and ages were studied. The birds were sacrificed, dissected and the visceral components of the respiratory system were exposed into a plane surface. The length was measured with the support of a millimeter based measuring gauge, and the weight was obtained via electronic precision scale. For the purpose of statistical analysis the T Student test was used with a significance level of P=0.05. The female Southern Caracara, larynx was significantly larger than in males. The trachea is small length than in chickens and that, the relationship between the corporal weight and the trachea and the lung's weight of the caracara are greater than the Gallus gallus domesticus.
