World Migratory Bird Day 2023 is here, focusing on the theme "Water: Sustaining Bird Life." On October 14th, people and organizations all over the world will come together to raise awareness and take action. Water is essential to the survival of migratory birds. From breeding to resting, and refueling during migration and wintering, migratory birds rely on lakes, rivers, ponds, coastal wetlands, and even moisture found in seeds, flowers, and mist.
