Each spring and fall, hundreds of species of birds migrate up and down throughout the Americas, seeking their preferred climate, food, and nesting locations. To prepare for their long journeys, they must have the right types of food sources available to them at the right times. Mismatches between when birds need food and when food is available can create major problems in ensuring birds have sufficient energy to fly to their destinations.
We know these relationships are changing, but don’t know how—we can’t "see" these changes. The changes within a given year are often subtle and hard to detect. But over time, these small changes add up and can dramatically influence how species interact with each other. We need your help to gather enough data, over enough time, to be able to see these shifts in interactions!
