dove, pigeon

Definition:

Doves and pigeons are two kinds of small, gray-brown birds that look similar. A dove is often thought of as being lighter in color, almost white.

Some languages have two different names for them, while others use the same name for both.
Doves and pigeons were used in sacrifices to God, especially for people who could not afford to buy a larger animal.
A dove brought the leaf of an olive tree to Noah when the flood waters were going down.
Doves sometimes symbolize purity, innocence, or peace.
If doves or pigeons are not known in the language area where the translation is being done, this term could be translated as "a small grayish brown bird called a dove" or "a small gray or brown bird, similar to a (name of local bird)".
If both a dove and a pigeon are referred to in the same verse, it is best to use two different words for these birds, if possible.
