The Macquarie Marshes
The Macquarie Marshes breeding site
The Macquarie Marshes in NSW provide important breeding and foraging habitat for an array of waterbirds. Part of the Marshes is listed as a Ramsar wetland of international importance. 2016 was an exceptional year in the Marshes for waterbird breeding, especially straw-necked ibis (Threskiornis spinicollis).
During our October 2016 visit to Monkeygar Swamp in the Marshes, straw-necked ibis had established nests on phragmites reed beds. Most nests contained at least one chick. A few Australian white ibis (Threskiornis molucca) were seen nesting with the straw-necked ibis, and glossy ibis (Plegadis falcinellus) were repeatedly seen flying in flocks and foraging within Monkeygar Swamp.
Magpie geese (Anseranas semipalmata) with chicks, brolgas (Grus rubicunda), pink-eared ducks (Malacorhynchus membranaceus) with chicks, musk ducks (Biziura lobata), nankeen night-herons (Nycticorax caledonicus) and intermediate egrets (Ardea intermedia) were all seen foraging near the Monkeygar Swamp colony.
Time-lapse and motion-sensing camera nest monitoring
Staff from the NSW OEH (Office of Environment and Heritage) installed 15 cameras on straw-necked ibis nests in early October 2016 within the Monkeygar Swamp colony. We will process these images and extract information about egg and chick mortality, and predation within the Monkeygar colony. Although there was no direct evidence of predation within the Monkeygar colony (eg. smashed eggs) we did observe a fox, feral pig and cat on the fringe of the colony. A swamp harrier (Circus approximans) and whistling kite (Haliastur sphenurus) were seen too.
Satellite tracking of bird movements
We deployed Geotrak GPS satellite transmitters on 5 adult straw-necked ibis (2 females and 3 males) in the Monkeygar Swamp colony. Birds were also fitted with leg bands for later identification. Gracy, Gill, Gough, Galaxy and Gigi are our birds from the Macquarie Marshes. All showed varied movements from Monkeygar Swamp.
Please report any sightings of banded birds or birds with transmitters to Heather McGinness: 0428124689 or the Australian Bird and Bat Banding Scheme (ABBBS) (02) 6274 2407 email@example.com.
