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.
Describe the bony features of the nasal cavity. The nasal cavity is mostly formed by the union of the maxillae. The ethmoid bone is at the rood of the nasal cavity. The perpendicular plate of the ethmoid and the vomer make the bony septum dividing the nasal activity into right and left sides. On the lateral walls of the maxillae are the inferior nasal conchae.
