Yes, birds do have salivary glands. However, their salivary glands are relatively small compared to mammals and produce a less viscous saliva. Additionally, birds primarily moisten their food with mucus secreted by the walls of their esophagus, rather than relying heavily on saliva for digestion.
Your salivary glands are located in and around your mouth. The major salivary glands are the parotid glands, submandibular glands, and sublingual glands, which produce saliva to help with digestion and protection of the mouth.
Humans have paired salivary glands.
The salivary glands are located in the mouth and secrete saliva into the oral cavity. There are three pairs of major salivary glands: the parotid glands, submandibular glands, and sublingual glands.
Saliva is produced by the salivary glands in the mouth. These glands release saliva to help with digestion, protect the mouth from bacteria, and keep the mouth moist.
The large pairs of salivary glands are the parotid glands, submandibular glands, and sublingual glands. These glands produce saliva to aid in the digestion of food by moistening and breaking down food particles.
