Participate in this fun, interactive lesson that allows students to think like a USGS Wildlife Biologist! This lesson explores how disturbances in the natural environment could impact the nesting habits of geese in the wild. In this activity, students analyze camera shots of different nests and evaluate how the length of incubation breaks taken by geese can vary due to local disturbances.
Past research has shown that a typical length of time for geese to incubate their eggs on a nest is about 30 days. During this 30-day period, the geese will regularly take breaks to eat and drink throughout the day. However, human activity and other disturbances in the area may force a goose to leave her nest for additional and extended periods of time. Whenever a goose leaves her nest, the eggs are unprotected from predators in the area. Increased predation of eggs could have an impact on local goose populations.
To gain a better understanding of the length of frequency of natural incubation breaks and if human and predators cause additional and longer breaks from the nest, the USGS Alaska Science Center used small cameras at nest sites in northern Alaska. Wildlife Biologists set up cameras at different nesting locations and recorded the geese during their incubation period. Camera shots were captured before, during, and after a goose left their nest.

Using photos from this research, we’ve developed a fun, interactive activity for students to practice analyzing research data like a Wildlife Biologist. This lesson is meant to help students learn about data collection, testing hypotheses, and evaluating results by looking through the camera image data collected by our wildlife biologist team. In this activity, students can split into groups and are assigned a different nest location. Students analyze their group photos, complete a data sheet, and then evaluate local disturbances and the length of time the geese were away from their nest.

Goose ResearchThe USGS Alaska Science Center has had a focus on addressing science questions related to geese in Alaska for decades. Information on these species is critical because all are important resources for subsistence and sport hunters in the state and outside of Alaska where these birds spend the winter. The large majority of goose populations in Alaska breed on national wildlife refuges (managed by...
