Chapter 1. Birds

Pre-existing transect waypoints have been established within the relevant target habitats (see table 1 & attached maps). Along these transects, points will be established from which bird survey data is collected. Duplicate the following procedure to obtain data within the assigned habitat. Bird surveys commence at dawn (known as the dawn chorus) and should be conducted in an orderly and quiet fashion. Good luck and have fun identifying the unique range of Australian avian fauna.

Equipment
  1. Measuring tape (50m)
  2. Flagging tape or equivalent
  3. Clipboard
  4. Field data sheet
  5. Pencil & sharpener
  6. Bird field identification reference
  7. Binoculars
  8. Timer or watch
  1. To establish points, determine a team member that has the most accurate pace measurement. To achieve this, each team member should pace out “what they believe” to be 10 meters. Measure each distance and assign the most accurate measurement as “distance keeper”.
  2. Pace out points along the transect as follows; the first point should be 50 meters along the transect from the origin (this will be the first point count sample location), the second point should be a further 100 meters along the transect (or 150 meters from the origin (see diagram below). Example transect line
    Example shows details for a 500 meter transect, however the principle is the same for any transect length.

  3. Mark each point and assign a code to each point. The codes can be marked on the relevant marking device (flag, stake) and transferred to the relevant data sheet when required.

Chapter 1. Birds (continued)

  1. When conducting a bird survey, data should be recorded from each point along the transect. When recording data keep the following limitation in mind; all birds that fly or are observed within 50 meters of the transect should be recorded. It sometimes helps to imagine a “bullseye” from each point within which data is collected (see diagram below).
Example transect line with data collection 
The above provides an example of how data collection should be carried out. The figure demonstrates how duplication of data can be avoided as there is no overlap of observation. NB: it is very important that duplication of data does not occur.

  1. To commence a bird survey, assign a scribe and record the start and later on, the finish time. The scribe is responsible for the recording of data and should keep time for the rest of the team.
  2. Stand at each point for a period of 10 minutes and record data as observed by all members. NB: Species observed while immobile at any point are not opportunistic observations.
  3. Walk slowly and quietly between points. Any species observed between points should be recorded as opportunistic. All birds observed outside the prescribed “bullseye” must also be recorded as opportunistic.

    NB: When your team comes across a bird that can not be identified in the field, take as many notes as possible on the field data sheet diagram (Birds Data Sheet) for future identification.
