You do not need expensive equipment to start watching birds. A pair of binoculars you can hold steadily, a free app, and an early start will take you further than most gear lists suggest. Here is how to choose each one.
Binoculars: read the two numbers
Most binoculars carry two numbers, for example 8x42. The first is magnification: 8x makes a bird look eight times closer. The second is the diameter of the front lenses in millimeters. Larger front lenses gather more light, which helps in dim forest, but they also make the binoculars heavier.
For birding, 8x32 and 8x42 are popular choices. As a rough guide, compact models have front lenses under 30 mm, midsize models 30 to 40 mm, and full-size models above 40 mm. Birding guides commonly recommend 7x to 10x, with 8x the most common. Stronger magnification narrows the view and shows every shake of your hands, so it is usually paired with a tripod and a spotting scope.
If you can, try several pairs in person, with your glasses on if you wear them, and practice finding a moving target before you buy.
A free app that listens
Merlin Bird ID, from the Cornell Lab of Ornithology, is free. It offers four ways to identify a bird: by sound, by photo, by answering five questions about what you saw, or by exploring species in the app. Sound identification was added in 2021.
Merlin works from regional downloads called bird packs, so before a trip, check that the pack for your destination is installed and see which species it covers. The app does not always get the answer right. Treat a suggestion as a lead to confirm with your own eyes or with your guide, not as a final verdict.
Keep a list with eBird
eBird is a global database, run by the Cornell Lab, where birders log what they see and share it with scientists. It is also the data behind Merlin: the Lab has said that the app learns from recordings and observations contributed by birders. Writing down what you saw, where and when turns an ordinary walk into useful data, and gives you a record to look back on.
Go early, and listen first
In a 2025 Cornell Lab study of tropical forests, most birds were far more vocal at dawn. The researchers found that territorial behavior and diet help explain why some species sing more at dawn. They found little support for the popular idea that morning air simply carries sound farther. Each species also tends to start at its own time before sunrise.
For you, the practical lesson is simple. Be on the trail before first light, stand still, and listen before you look. Many birds are heard long before they are seen.
A simple starter checklist
- Binoculars you can hold steady for a long time
- Merlin installed, with the right bird pack for your region
- A notebook or the eBird app
- An early start, comfortable shoes and water
- Patience
