Meet Mr. and Mrs. Jacobin. Yes, another hummingbird in Costa Rica does not have “hummingbird” as a part of its common name. There are hummingbirds that are mangoes and woodnymphs and coquettes and thorntails. This is the White-necked Jacobin, one of the most frequent visitors to the feeders at Costa Rica’s Rancho Naturalista. I got to wondering about its name. I know the word Jacobin as it relates to Dominican monks who were nicknamed Jacobins in the Middle Ages when their first convent was located on the Rue Sainte-Jacques (Jacobus in Latin). As it turns out, the White-necked Jacobin was given that name because of the similarity of his deep blue/black head and neck feathers to the black hooded cape that the Jacobins wore over their white robes. Of course the females don’t have that distinction but are beautiful just the same.
