Need help sexing my Red-Browed finches
Posted: 21 Dec 2016, 19:25
Three months ago I purchased three "pair" of red-browed finches. These were all young juveniles, and when I obtained them I thought I indeed had three hen/cock pairs. I placed them all in the same cage hoping that I would see some natural pair-bonding or at least hear cock courtship calls to confirm the cocks. Well time has passed, and to date I have neither observed any pair bonding nor any courtship calls, so I am beginning to wonder whether I actually have three cocks and three hens or something else. This post is thus a call for help from the far-more-experienced-than-me members of the forum.
I'm going to call the 6 specimens by their leg band colours: brown, red, orange, yellow, green, blue; yes, if there are any electrical engineers among you I use the engineers colour code when banding my finches. Here are the six specimens:
(1) Brown ring

(2) Red ring (the middle bird)

(3) Orange ring

(4) Yellow ring

(5) Green ring (bird on the viewer's right)


(6) Blue ring (bird on the viewer's left)


I'm reasonably sure that Brown and Orange are cocks, given the long brow and obvious shoulder stripe. Red originally looked to be a hen due to the very short brow but now looks to be a cock. I am not sure of the sex of the other three, although if I had to guess I would say Yellow is a hen, Green is maybe a hen, and Blue is maybe a cock. You can see multiple images of each specimen using the links below, but be warned that the first several images were taken three months ago, so the bottom-most images are most recent.
(1) Brown (no recent images)

(6) Blue (recent images at the bottom of the webpage)

As a matter of interest these birds were imported from Europe and I had to pay over $700 Aussie dollars for each pair, so I am rather envious of you guys back home paying considerable less. On the other hand imports are not prohibited here (Japan) so I perhaps have access to some species that you don't have in Australia.
As always, thanks in advance for any help you may give.
