The Brown Thornbill is a very common bird in the Blue Mountains of NSW. They almost always appear in flocks of several birds up to dozens of them. They are hard to get good photos of since they move around so often so I was stoked when I got these ones.

I am fairly sure these photos are Brown Thornbills rather than Striated Thornbills (or another Thornbill) due to the rufous (reddish-brown) around the rump and inner tail, and especially due to the reddish coloured eye. According to Simpson and Day there is no other Thornbill or related bird with a reddish brown eye in the East of New South Wales. The Striated Thornbill is also common in the Blue Mountains and I find it hard to tell the difference, without a close up of the eye like in the photo below.

Some Birdwatching Resources

Tasco Essentials 10x50 Binoculars - Brown Thornbill - Acanthiza pusillaTasco Essentials 10x50 Binoculars

I have the 8x40 of this series, which I bought because I saw them on special, and they had a much clearer image than the cheap no-name brand binoculars I had before. I would have got 10x50 instead if they had been on special also. These are great basic binoculars which can be used for birdwatching, stargazing, etc.

The first number (like 8 or 10) refers to the magnification, so bigger numbers mean you can see closer up, but the image will shake around more. The second number (like 40 or 50) is the diameter of the large lenses in millimetres. Bigger numbers mean more light gets in, so the image is clearer and better, at the expense of being larger and heavier to carry around.

With binoculars, once you get above the really cheap models (like $30-50), the image quality is pretty good. You can pay a lot more, like a few hundred dollars, or $1000 or $2000 even — but most of what you get isn't so much raw image quality but other features like durability, being waterproof, better lens coatings, image stabilisation, etc. Cheaper binoculars are more delicate and if not treated gently the two sides can go out of alignment with each other.

The product information says, "Tasco has been America's popular choice in sports optics for over 50 years. For half a century we've made it our mission to design and manufacture quality optics at prices that will fit any family's budget.
