Shiluach Haken

Is the attached picture a kosher bird for שילוח הקן

Shalom!

Thank you for your question.

It does indeed appear to be dove and is a bird that is eligible for the mitzva of shiluach haken.

As you allude to in your question, allow me to emphasize that only kosher birds are eligible for the mitzvah of shiluach hakan. Nevertheless, even birds that are not eaten are still eligible for the mitzva as long as they have the physical signs of a kosher bird. As such, the mitzva may be performed on pigeons, doves, geese, ducks, sparrows, robins, cardinals, and orioles. The mitzva is not performed with clearly non-kosher species of birds like eagles and ravens.
