Yesterday, from Bittern Hide we saw an aggressive swamp hen chasing another 
swamp hen, then pushing it under water and trying to hold it's head under water 
as it pecked it's head.  The bird escaped but the chasing continued with more 
swamp hens joining in.  Unfortunately we were not able to stay long enough to 
really sort things out; but there was no doubt about the aggressive behaviour. 
Why such behaviour?
