Nesting & Hollow Watch is a citizen science project that monitors natural tree hollows, nest boxes and breeding activity of local birds and possums. The project helps track which species are using hollows, how often they breed and where additional habitat support may be needed across the local corridor network.

Project description

Volunteers visit assigned hollows or nest boxes and record signs of use such as feathers, scratches, droppings, nesting material or direct sightings. Regular monitoring builds a picture of hollow availability, competition between species and the success of installed nest boxes. This information supports long term habitat planning and restoration work.

What volunteers do

• Visit a designated hollow or nest box on a regular schedule.
• Observe from a safe distance without disturbing wildlife.
• Record any signs of use such as nesting material, feathers or droppings.
• Note species seen entering or leaving the hollow.
• Photograph the hollow opening and any visible activity.
• Submit observations with date, time and location.

How to do it

1. Select or receive a site: Volunteers are assigned a natural hollow or nest box. Each site has a unique ID and coordinates to ensure consistent monitoring.
2. Approach quietly: Move slowly and avoid sudden noise. Wildlife may be resting or feeding inside the hollow.
3. Observe from below: Stand back and look for movement, sounds, feathers, scratches or fresh droppings. Do not tap the tree or attempt to look inside.
4. Record evidence: Photograph the hollow entrance and any signs of activity. Note species if confidently identified, or describe colours and size if unsure.
5. Check nest boxes safely: If monitoring a nest box with a viewing lid, only open it if trained and authorised. Otherwise, observe from the ground.
6. Submit data: Enter the date, time, species, signs of use, photos and any notes about behaviour or threats such as bees or feral species.

What the results will be used for

• Tracking breeding activity of parrots, owls, kookaburras and possums.
• Identifying hollow shortages in key parts of the corridor network.
• Planning where new nest boxes should be installed.
• Monitoring competition between native species and feral species.
• Assessing the success of revegetation and habitat restoration projects.
• Supporting conservation planning and funding applications.

Equipment needed

• Smartphone or camera for photos.
• Notebook or digital log for observations.
• Binoculars for safe distance viewing.
• Site map or GPS coordinates.
• Optional: small torch for low light conditions, used only from the ground.
