Hi all :)
could you mods please create a specific section for jacarinis? I wrote a profile for them (and african silverbills) a while back.
And also, my male doesn't seem to be colouring up. He has a bit of blue/black on him, but not much... is it not time yet? or is he just really slow?
Thanks!

My jacarinis normally coloured up when it got warmer, wouldnt worry too much jayburd, he'll be fine. Just hope that he is interested in his partner.

The older males colour first, I have young males from last season that are still nowhere near full colour.
Maybe it is built into them,so the breeding males from the previous season have the advantage of setting up their breeding area before the young upstarts are ready to compete.

Thanks! that's a bit of worry of my mind... yes he seems to be interested he has been looking in wicker baskets all morning, competing with the parrot finch - they both like the same basket! put another one close by at the same level and that seemed to sort things out :)

Jay dont panic, males willcolour up when ready and often will nest and breed before attaining full color. We have the first to out for the season and the male is a very blotchy blue/black and brown.

At least you know you have a young bird, old birds stay black.

Jay, yes your right, better color greater vigor means survival of the fitest and esuring your genes are passed on in the wild. As Jacs are best in the avairy as single pairs we generally keep them as single pairs, so in such an altered environment the birds commitment to survival of the fittest is not tested and to a lesser extent seasoanllity (seeds and insect blooms) are not the norm as we feed to optimum levels. As he is one male he is the best available to the hen at this point in time and so colouring up, singing, boasting, fighting all goes out the window and nesting happens.
Remember these birds are in an aviary not in the wild. This of course goes out the window when you have multiple pair species in a an aviary. Even then there can be exceptions to the rule. I have a colony of weavers where 1 set have already paired off and he has built a nest. At present he has one red feather on his chest and really isnt hissing or buzzing, having said that he is definately dominate of all the males in the colony and so has won a heart.


Thanks Buzzrd good to know about old birds staying black.
Cheers

Maybe also try a bunch of brush/tea tree placed low in the aviary. I haven't had Jacs for years but can always remember their distinct preference for nesting in the lower forks of brush provided and insatiable appetite for any moths, spiders, etc they could catch in the aviary as well as any livefood provided for them when feeding young.

Mine use to nest in the crown of a fern about 18" off the ground when I had them.
