Hypothesis

Do eagle owls use faeces and prey feathers as visual signals to indicate their reproductive status?

Conclusion

Eagle owls may use faeces and prey feathers to communicate their reproductive status to other owls.

Supporting Evidence

  • Eagle owls leave visible faeces and feathers near their nests during the breeding season.
  • The presence of these markings may deter intruders from approaching the nest.
  • Non-territorial owls do not mark their territories with faeces or feathers.

Takeaway

Owls might use their poop and feathers to show other owls that they are having babies.

Methodology

The study involved observing the spatial and temporal distribution of faecal marks and plucking sites in 20 breeding territories of eagle owls.

Potential Biases

Potential biases in observing owl behavior and environmental factors affecting marking.

Limitations

The study is speculative and requires further experimental validation.

Participant Demographics

The study focused on eagle owls (Bubo bubo) in the Sierra Norte of Seville, Spain.
