What you’ll learn

  1. A stopover is a fuel stationExplain why migratory birds need wetlands for food, rest, and timing between flights.A stopover is valuable when birds can recover energy and find safe resting space.
  2. Tidal flats serve different billsConnect tides, sediment, bills, prey, and wetland edges to bird habitat.Changing water and mud create a shifting set of feeding opportunities.
  3. Networks across seasonsDescribe why migrants depend on networks of wetlands across a flyway.A route is only as strong as the connected sites that support it.
  4. Disturbance and climateEvaluate how disturbance, drought, sea-level rise, and restoration alter stopover habitat.Habitat quality changes with weather, people, elevation, and the processes that build wetlands.
  5. Monitor and protectUse counts, behavior, tracking, and habitat measurements to judge conservation actions.Good monitoring links bird behavior to the wetland conditions that make migration possible.

Questions this course answers

What makes a wetland a useful stopover?

A useful stopover provides food and safety during the pause between flights.

Why should conservation protect roosts as well as mudflats?

High tide can cover feeding mud, so birds need safe resting places nearby.

Put the tide-linked sequence in a sensible order.

Tide changes exposure, access to prey, and where birds can go next.

What does habitat diversity allow?

Different sediments, depths, and vegetation support different feeding tools.

Why can several small wetlands matter as a network?

Migrants may need multiple sites separated by long flights.

What is a staging area?

Birds may gather, refuel, and wait for favorable conditions before departure.
