Using Binoculars

Learn how to watch birds more clearly by understanding the basics of how to use binoculars, from adjusting the focus to scanning the landscape.

Binocular parts

  • Neck strap - The cord for around your neck so you don’t drop them.

  • Eye pieces - Where you look through your binoculars. Many have soft rubber eyecups that can be twisted up or down to reduce glare.

  • Diopter rings – This small adjustment (usually on one eyepiece) helps fine-tune the focus if one eye is stronger than the other.

  • Focus wheel – The central wheel adjusts the sharpness of the image for both eyes. You’ll use this the most while birdwatching.

  • Objective lens – These are the large lenses at the front of the binoculars. They collect light and help create a bright and magnified image.

Setting up your binoculars

1. Put the neck strap around your neck to keep your binoculars safe and accessible.

2. Adjust your eyecups. Glasses on? Fold the eyecups down. No glasses? Keep the eyecups up to block out extra light.

3. Focus each eye by looking at a distant object. Close your right eye, and use the focus wheel to sharpen the image for your left eye. Then close your left eye, and use the diopter ring to focus for your right eye. Once done, both eyes should see clearly with just the focus wheel.

How to look at birds

  • Scan the area with your eyes - Look around with your naked eye. Take note of any trees, river bends or other features. Listen for bird calls too.

  • Keep your eyes fixed on the spot you want to look at. Raise your binoculars to your eyes and line of sight without moving your head.

  • If you don’t see any birds, scan the area with your binoculars. Start by focusing on the horizon, then slowly pan across. Look for movement, colour and shapes.

  • Use the focus wheel to sharpen the image. This is especially helpful if a bird is hiding among leaves or branches - adjusting the focus can help you “see through” the vegetation.
