I think they maybe juveniles or crosses of two species.
No interactions present.
I would like to know what species these birds are, and have found no information on them since i took these photo's back on the 18th Sept 2009.
I have looked in countless books in the libraries, and nothing.
Do you think these birds are the cross breed of those white domestic ducks & a mallard, as they followed these white ducks where ever they went, Mmmm thanks for your input.
The fact that 3 inyour photo' look exteremly similar strongly suggests that they are very closely related - probably brothers. Beyond that, most people's guess would be as good as the next person's.
