Xantus Hummingbird Species. Xantus Hummingbird is a medium-sized hummingbird that can only be found in Baja, California. The bird is deemed to be the most distinctive among the few Baja specialty birds. It grows to a length of 3-3.5 inches, and weighs about 3-4 grams upon maturity. It was named after a Hungarian zoologist, John Xantus de Vesey.
The nasal septum, the division between the left and right airways of the nose, is made of three structures: the vomer bone, perpendicular plate of ethmoid bone, and its cartilage.
The nostrils, which form the external entrance of the nose, lead into the two nasal cavities, which are separated from each other by the nasal septum, a partition formed of cartilage and bone. Three bony ridges project from the outer wall of each nasal cavity and partially divide the cavity into three air passages.
