Hypothesis

Deer mice have a strong navigational instinct that allows them to return to their homes from significant distances.

Conclusion

The study found that deer mice can return to their homes from distances of up to 1,200 meters, suggesting a strong homing ability.

Supporting Evidence

  • Deer mice returned to their homes within 24 hours of being released.
  • Some mice traveled distances of up to 1,200 meters to return home.
  • Nine mice were captured once, and six of eight captured twice returned multiple times.

Takeaway

Deer mice are really good at finding their way back home, even if they are let go far away.

Methodology

The researchers live trapped and released deer mice at increasing distances from a bunkhouse to study their return behavior.

Limitations

The study was conducted in a specific location and may not represent all deer mice populations.

Participant Demographics

Equal numbers of male and female, adult and juvenile mice were captured.
