Comb-crested	jacana	
                   Kakadu	is	home	to	approximately	280	different	
                   types	of	birds,	including	the	comb-crested	
                   jacana.		
                   	
                   These	birds	are	unique	due	to	the	bright	red	
                   combs	on	their	foreheads	as	well	as	their	
                   enormous	splayed	feet	which	creates	the	illusion	
                   that	they	are	‘walking	on	water’.		
                   	
                   The	birds	range	from	20-24cm	in	size		
                   	
                   	
                   	
                   Plants:		
                   	
                   The	types	of	plants	found	in	a	wetland	depend	on:	
                       •  Whether	a	wetland	has	mostly	fresh,	saline	or	brackish	water	
                       •  Surface	and	underground	drainage	
                       •  Frequency	of	flooding	
                       •  Other	factors	such	as	soil,	temperature,	rainfall	and	topography.		
                   	
                   	
                   Kakadu	wetlands	are	home	to	over	2000	
                   plant	species.		
                   	
                   One	of	the	most	common	plant	species	
                   found	are	water	lilies.	The	roots	of	the	lilies	
                   can	be	dug	up	and	used	as	a	source	of	food.	
                   They	contain	starchy	seeds	that	can	be	
                   ground	into	a	paste	and	made	into	small	
                   cakes.	
                   	
                   	
                   	
                   Biophysical	interactions:		
                   •  Located	in	the	tropics,	between	12	and	14	degrees	south	of	the	Equator.		
                   	
                   •  Climate	is	monsoonal,	with	two	main	seasons:	the	dry	season	and	the	wet	
                       season.		
                          à	Dry	season:	low	humidity	and	low	levels	of	rain	
                          à	Wet	season:	warm	temperatures,	higher	levels	of	rain	
                   	
                   •  Annual	rainfall	is	from	approximately	1,300-	1,500mm	of	rain.		
                   	
                   •  Temperatures	in	the	region	range	from	19	to	33	degrees,	with	the	coldest	
                       temperatures	recorded	in	June,	July	and	August.
