The Mauritius kestrel (Falco punctatus) is a bird of prey in the family Falconidae endemic to the forests of Mauritius, where it is restricted to the southwestern plateau's forests, cliffs, and ravines. It colonized the island and evolved into a distinct species from other Indian Ocean kestrels, probably during the Gelasian or Early Pleistocene periods. The Mauritius kestrel can reach a size between 26 and 30.5 centimetres (10.2 and 12.0 inches), with a mass of up to 250 grams (8.8 ounces) and rounded wings with a span of approximately 45 centimetres (18 inches). Males are slightly smaller than the females. It is a carnivorous bird, eating geckos, dragonflies, cicadas, cockroaches, crickets, and small birds. It hunts by means of short, swift flights through the forests. In 2022, it was proclaimed the Mauritian national bird to mark the 30th anniversary of the Republic of Mauritius. This Mauritius kestrel was photographed in the Ebony Forest near the village of Chamarel.

MLS play returned with a special tournament in July hosted at a bubble site; Seattle then hosted matches at CenturyLink Field (pictured), their home stadium, behind closed doors. The Sounders only played 22 regular season matches after several were canceled; the 2020 U.S. Open Cup was also canceled. Seattle qualified for the playoffs as the second-placed team in the Western Conference and won a second consecutive conference championship. They lost 3–0 in MLS Cup 2020 against the Columbus Crew SC. (Full article...)
