Well, I've learned something today. The image here is the seal of the state of Louisiana (though the motto has been inexplicably edited down from the official "Union, Justice, & Confidence"). The state bird of Louisiana is the brown pelican, but the image on the seal is the medieval Christian "pelican in her piety," as reiterated by a 2006 resolution in the state legislature requiring the three red drops of blood to always be featured on the mother pelican's bosom.
