Bird research: Sulphur-crested Cockatoo and Australian White Ibis

John Martin, Wildlife Officer

Sulphur-crested Cockatoo research with social media

Research is currently under way that involves wing-tagging sulphur-crested cockatoos (Cacatua galerita) within the Sydney region. The aim is to monitor cockatoo movements, breeding and habitat preferences.

Report your cockatoo sighting

If you see a wing-tagged cockatoo please report the tag number and colour (e.g. 142-green or 011-yellow) and location in one of these ways:

Donated funds will be used to conduct GPS tracking and to maintain the iApp and database. The GPS tracking aims to learn more about the cockatoos' foraging behaviour. From the resighting data of wing-tagged birds we have learnt a lot about the birds' movements and in particular their foraging movements within urban areas. However, we have recorded few records of the birds using natural areas; for the obvious reason that few people are in these areas to record the birds' presence. With the GPS transmitters we will quantify if the birds use urban areas more frequently than natural areas. The transmitters we are using weigh 20 g (this equates to ~2.5% of the mass of a 800 g cockatoo), are solar powered and recorded a GPS position up to every 15 minutes. The data collected is transmitted via the GSM mobile phone network each day so we can see in almost real-time the birds movements. We plan to track existing tagged birds to compare their known movements from reported sightings with the GPS movement data. We plan to track individual birds for a short period (e.g. 1-3 months) and then recapture the bird and remove the transmitter.

Australian White Ibis research needs your help

Research is currently under way that involves banding and wing-tagging Australian white ibis (Threskiornis molucca) within the Sydney region. The aim is to monitor ibisí movements, breeding and habitat preferences. Colour-banding and numbered wing-tags allow identification of individual ibis; observations have been received from across the Sydney region and as far away as Shepparton (Vic), Coffs Harbour (NSW), Brisbane and Townsville (Qld).

Each ibis is fitted with an individually numbered metal band (e.g. 121-53662). Birds may additionally be fitted with a site-specific colour band or tag (e.g. green or blue band or black tag (see pictures), which allows the banding location of a bird to be easily determined. If an ibis is not wing-tagged it may be banded with two additional colour bands (e.g. pink/pink or yellow/pink) from the eleven colours, this allows easy identification of individual birds without having to read the numbers on the metal band.

Please report all observations of banded white ibis to ibis.sightings@gmail.com wherever they are observed (across Sydney, throughout Australia and as far as Papua New Guinea and the Moluccas Islands). The critical information to report is the tag number and colour or the position of the bands and their colours. An easy way to do this is to note each part of the birdís leg. For example:

  • Left Upper (thigh) - Nothing
  • Left Lower (shin) - Yellow/Pink (top to bottom)
  • Right Upper - Metal
  • Right Lower - Green

Solar-powered Ibis

Ibis just entered the 21st century with GPS solar powered transmitters to track their movements. The adult ibis were originally colour-banded as adults (> 3yrs) in 2007 and 2008. Through monthly surveys over the last seven years we have recorded that ~80% of the study birds show high site loyalty to Hyde Park, the Domain and the Royal Botanic Garden; located within the City of Sydney. But we know very little about the movement behaviour of these birds.

As the transmitters are solar powered they can operate for multiple years, however our plan is to retrieve the transmitters after 1-2 months and redeploy them on additional colour-banded birds. The transmitters will record highly accurate (± 5-15 m) GPS fixes each hour. The location data will be relayed to the research team via satellite (www.geotrakinc.com) and through the mobile phone network (www.ecotone-telemetry.com); we would like to say a BIG thanks to both of these companies for their generous support! Click here to view blog.
