Graham's comments

as the name suggests, the normal bird has a red head
Sea Green - an attractive mutation where the head mask is orange and the green differs from normal (shown below - right)
Various pied forms exist

the cage size does not matter - but the 600mm depth seems important - particularly for parent-rearing

however, it seems appropriate to give this very active and curious bird as much space as possible
this isn't exactly a colony bird but nor are they overly aggressive towards each other in a large, well planted aviary - even when breeding

they do fine on either of the normal seed mixes described on 'Graham's Overview' page

Sexing

sexing can be quite difficult - signs to look for are:-

firstly, only the cock sings
secondly, the red on the head is stronger on the cock bird
thirdly, the red on the rump is straight on the hen but round on the cock bird

when in condition,  will
nest at any height

nestbox - half-fronted can be
hung either inside or
on the outside of the cage

seem to prefer an 'inside' nest box to
face the bird room entrance
presumably to see who,
or what, enters

clearly we can worry too much

this self-built nest is between
the rafters and a trap cage
nest boxes were available

best described as 'rough and ready'
some coconut fibre and
bamboo leaves
'thrown' together

aggression in this small colony of 6 (plus 5 Tricolors)?
not a bit

this aviary has a flight of 4M x 2.5M and is lightly planted

2 Sea-green pairs nested at the same time
other birds - including Sea-greens - would land on the top of the trap cage - 4" from the nesting pair - nothing happened at all

re Graham's comments on the nest facing the entrance
the self-built nest roughly faced the entrance but the nest box chosen backed onto the wire of the entrance porch
despite others being available with a much better 'view'
