Japanese quail
Normally, the Japanese quail has been considered to possess an underdeveloped sense of taste, this being evidenced by their inability to distinguish different kinds of carbohydrates presented to them. However, studies have shown that a limited ability to taste is indeed present. Evidence for this includes quail individuals exhibiting preferential choice of sucrose-containing solutions over simple distilled water and the avoidance of salty solutions. Though the Japanese quail possesses an olfactory epithelium, little is known about its ability to sense smell. Despite this, certain studies have revealed that these birds are able to detect certain substances using only their sense of smell. For example, they have been reported to be able to detect the presence of certain pesticides, as well as avoid food containing a toxic chemical called lectin, using only the sense of smell. Through nasolateral conversion of the eyes, the Japanese quail is able to achieve frontal overlap of the eye fields. Long distance perception occurs with a binocular field accommodation. In order to maintain focus on a certain object while walking, the quail will exhibit corresponding head movements. The Japanese quail has also been shown to possess color vision, its perception of color being greater than that of form or shape. Not much is known about "Coturnix japonica" hearing; however, it has been shown to be able to distinguish between various human phonetic categories.
