Le pluvian fluviatile ou Pluvianus aegyptius (en latin) est un oiseau appartenant à la race des limicoles trapus. On le reconnait par ses couleurs  grise, blanche, noire au-dessus, un ventre chamois avec une bande pectorale noir. Cet oiseau possède  des pattes courtes, un bec  court, pointu et de couleur noire. Il possède un capuchon, un masque oculaire et un manteau noir. Son vol est rapide et bas. Il vit au bord de l’eau et se nourrit principalement d’insectes, de coquillages et de lézards. C’est une espèce sédentaire. Il faut noter qu’il n’existe aucune différence entre le mâle et la femelle.

L’espèce est de l’ordre des charadriiformes et elle est monotypique. Le Pluvianus aegyptius est le seul représentant de la famille des Pluvianidae. Il existe une relation de symbiose entre le Pluvianus aegyptius et le crocodile. Il joue le rôle de « brosse à dent » chez le crocodile en le débarrassant des restes de sa nourriture. En Côte d’Ivoire il a été aperçu à la volta noire, c’est une espèce assez rare. Selon l’Union Internationale pour la Conservation de la Nature (UICN) l’espèce est de préoccupation mineure. Son cri est « tchirk-tchirk-tchirk ».

  4. — Attorney General Merrick Garland on Wednesday defended a memo aimed at combating threats against school officials nationwide while Republicans insisted he rescind the directive. He signaled he had no plans to do so despite their criticism.

  5. Republicans say Garland went too far in instructing Justice Department divisions to coordinate with local law enforcement. In his memo Garland said there had been “a disturbing spike in harassment, intimidation, and threats of violence against school administrators, board members, teachers, and staff who participate in the vital work of running our nation’s public schools.”

  6. Republicans on the Senate committee also seized on a memo from Leif Johnson, the acting U.S. attorney in Montana, to the state attorney general, county attorneys, sheriffs and school officials in the state. The memo spells out federal crimes that could be used in prosecutions for violence, harassment or intimidation of school board officials.

  7. The Montana memo, obtained by The Associated Press, cites about a dozen federal statues from conspiracy to deprive someone of civil rights to stalking and “anonymous telephone harassment.” It instructs the recipients to contact the FBI “if you believe that a person has violated one of these statutes.”

  8. The original letter asked for the federal government to investigate cases where threats or violence could be handled as violations of federal laws protecting civil rights. The association asked for the Justice Department, FBI, Homeland Security and Secret Service to help monitor threat levels and assess risks to students, educators, board members and school buildings.
