I took this photo in the Humbug Scrub area which is part of the Adelaide Hills about 40Km north of Adelaide. The terrain was quite hilly, near water and a few open area patches amongst some low lying scrub and occasional gum trees. The bird flew quickly from some low lying scrub, briefly landed on this branch (got this photo in as luckily I was pre focused on this branch) then in a split second flew away never to be seen or heard again. This was the only photo I got. My original thought (and this is how I have filed it) was that this was a White-browed Scrubwren, but its eyes are grey not yellow as with Scrubwrens. My next thought was a Chestnut-rumped Heathwren (CRHW) because of the colouring of the rump and the large feet, but I am not certain. CRHW are known to be in the Adelaide Hills area although I am not sure if they are this far north. Another alternative could be a Shy Heathwren, of which I have plenty of photos and I don't believe this is one. The area this was in would not suit a Shy Heathwren. Can anybody help with the ID of this bird.

I think this is a white browed scrubwren. Ssp frontalis. There is strange red coloration on the branch that the bird is perched on and on the feathers of bird. Perhaps this is a processing artefact.

Thanks Sandy, I tend to agree that it's a Scrubwren. The magenta colouring throughout the picture is only when I view it on BLP website, it is not on my original. I will check my monitor again using my Spyda 5. The monitor is new so there could be a problem with not showing magenta properly.

It does look a lot like a White-browed Scrubwren but I'm certainly no ID expert. Maybe a young or immature bird?

The main reason for responding though is to reinforce Sandy's comments that something odd is going on with the colour in this shot. I don't know what the issue is but you say it only appears when on the BLP website. It may be that you are not converting your image to sRGB colour space? This is the default for almost all web display. If you are using a different colour space and saving your image in that different colour space, it can have a significant effect on how the colour looks when mapped to sRGB as the browser assumes the photo is being presented as sRGB. It may also be that you've added saturation or a camera picture style that adds significant saturation. This will likely exaggerate any issue with incorrect colour space.

Thanks heaps Glenn, I grabbed the original PSD file and exported it as a JPEG sRGB and it recreated the same colour cast that I see on the image in BLP. I believe you are correct and in future I will convert all my photos that I send to BLP into sRGB colour format. I use Adobe RCG 1998 in photoshop as that was recommended by most users. As over 50 percent of my photos are of birds, should I be changing from Adobe RGB1998?

Hi Gunther, as I said if you post anything to BLP or anywhere else on the web (so the image is viewed from the internet via a web browser), it's almost essential to convert to sRGB as just about every browser out there assumes that's what's being used. Adobe RGB is a wider colour space and useful for editing or viewing in software that supports that colour space. By all means, keep all your files as Adobe RGB but whenever it leaves your computer for the internet, make sure it's in sRGB colour space. Also, watch out if you ever get your photos printed. Professional printing labs will tell you what colour space to provide your photo in. If you don't use that, it's likely your photo's colours won't print correctly. The default, again, is sRGB and it's likely most consumer-level printing services will expect a file to be in that colour space.

One thing that should not happen though is that the photo will look different when converted to sRGB (except in quite subtle ways). If you are using Photoshop or any other reputable image editing software, the software will look at the colour space metadata tag of your image and render it correctly no matter what colour space you use. So a photo in Adobe RGB should look pretty well the same when converted to sRGB in your image software. You indicate you converted to sRGB then the colour cast appeared; well, that should not happen. The problem only happens when the viewing application (like a web browser) thinks the colour space is sRGB when it's actually something else like Adobe RGB since the individual RGB values of each pixel map to somewhat different colours in the two different colour spaces.. So I'm not sure why you are seeing what you are seeing.
