The Eastern Spinebill is an extremely common bird in gardens in the Blue Mountains. It has a distinctive call which sounds a bit like "sawing" (it makes sense when you hear it), and a more common call which is a series of "bip bip bip bip bip bip bip bip bip" notes, very fast and all the same.

The Eastern Spinebill never stays in the one place very long, and it buries itself inside the flowery bushes that it eats from so it is harder to get a good photo than it should be for such a common bird.

Some Birdwatching Resources

Tasco Essentials 10x50 Binoculars - Eastern Spinebill - Acanthorhynchus tenuirostrisTasco 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.
