Waterbird use of farm dams in south-eastern Australia: abundance and influence of biophysical and landscape characteristics

Table 4 Mean density of birds (birds/ha) by functional groups and species (species/pond) on farm dams, billabongs, and the single dairy waste stabilisation pond (WSP)

	Shorebirds (Charadriiformes)	Long-legged wading birds	Swamphens and coot (Rallidae)	Pursuit predators	Diving	Dabbling	Filtering	Herbivorous	Total abundance (birds/ha)	Species richness (species/pond)

Note that these data are included purely for descriptive purposes, not comparative purposes. There is only one WSP and all the billabongs are located in the same area, so it is not possible to infer differences between the types of ponds (Numbers in parentheses represent 1 standard deviation. Not shown for WSP because there is only one pond)
