Birdwatching, or "birding" is one of the most popular hobbies to enjoy outdoors. Millions of people all over the world participate in some form of birding. One of the main reasons for birding's popularity is that it's inexpensive - all you need is a field guide or birding app for your smartphone and a good pair of binoculars. Whether you're a dedicated birdwatcher or you just like seeing what shows up at the backyard feeder, the most vital tool for appreciating the natural beauty of birds is a binocular optimized for daytime use.
So what makes a binocular good for birding?
Quality optics, for starters. Image sharpness and brightness are vital for a pleasing birdwatching experience. Anti-reflection coatings on binocular optical elements help to maximize the amount of light that passes through a binocular. Binoculars with quality, fully coated, or better yet "fully multicoated optics" are ideal for bright, sharp views, since they allow a maximum amount of light to be transmitted through the binocular to reach your eyes.
Another important factor to consider when comparing binoculars for birding is power, or magnification. While it's tempting to assume that more power is always better, it's just not true. Binoculars with magnifying power of 7x or 8x are arguably the best for all-around birding. Such moderate magnifications make it easy to hold binoculars steady for stable, shake-free observations and usually provide a wider field of view to explore. While more powerful 10x or higher binoculars may come in handy for viewing over longer distances, they are more difficult to hold steady and usually also have a narrower field of view.
You should also pay special attention to the size of a binocular's front lenses (also called "objective lenses") when shopping for a good birdwatching binocular. Objective lenses (the front lenses of a binocular) measuring 35mm to 42mm in diameter are preferred for birding binoculars, and many quality compact models with 26mm lenses also perform admirably during the day. You don't really need larger lenses unless most of your observations will occur at dawn or dusk. Binoculars with 42mm lenses gather ample light for bright, clear daytime views of birds and wildlife. Binoculars with 42mm and smaller objective lenses are usually more portable and compact than binos with larger lenses, and you'll appreciate their relatively smaller sizes when you take a birding binocular along with you on a hike, camping trip, or birdwatching expedition.
Another specification to be aware of is a binocular's close focus or near focus distance. This defines how close you can be to an object while obtaining a focusable view in the binocular. A short close-focus distance of 10 to 20 feet or less is a plus for studying birds at close range.
Would you like to take part in the fastest growing recreational activity in the United States? Just pick up a pair of binoculars and point them at the nearest ball of feathers. Yes, bird watching (birding) flies highest among the flock of fastest growing recreational activities in the US. "Why bird watching?", you may ask. Here are a few of its allures: beautiful scenery, tranquility, a chance to get away by yourself or a reason to get together with a few friends, a little exercise, a chance to visit new places, a motivating focus for your outings, a chance to learn a lot or a little, a large established and (usually) friendly community of birders, and finally the great aesthetic pleasures given by the birds themselves. Whether you become a birding fanatic or just dabble around the edges of the avian community, once you take that first bird hike, you will be smitten.
One of the best things about becoming a birder is how easy it is. Many people start in their own backyards. Bird-friendly landscaping and a bird feeder or two often result in attracting several different kinds or species of birds. Every outdoor environment hosts a least a few birds. The local, state, or national parks host dozens or hundreds of different species.
You will need a pair of binoculars. Binoculars enable a person to see the brilliant red cheek stripe of the red-shafted flicker, or the crest of feathers at the top of the head of the oak titmouse. Binoculars bring forth the exquisite streaked and scalloped patterning of the California quail, which can otherwise appear as a comical brown tufted orb skittering between the bushes.
Purchasing binoculars might seem a bit daunting-there are so many to chose from. Do not despair. First, take an honest look at your budget. The price range of binoculars is from twenty-five dollars to several thousand dollars. Most of that price difference comes from the quality of the optics (glass)-its light gathering ability and precision at transmitting the light. It is a good idea to have the optics multi-coated. The coatings reduce glare on the subject and eliminate the "halo effect" that can occur without the coatings. A serviceable pair of binoculars can be had for between $40 and $300.
Binoculars are labeled with two numbers. For example, they may read 8x40 or 10x50. The first number refers to the magnifying power (the object viewed looks 8 or 10 times closer than it actually is). The second number refers to the front objective lens size in millimeters. A ratio of 1 to 5 between the two numbers (the magnification and the lens diameter) allows in the optimal amount of light for a given magnification. The 8x40 binocular is probably the most popular variety, but 7x35 or 10x50 also work for birders.
When choosing binoculars, make sure that they are comfortable for you. You will spend much time with your arms up, holding the binocular to your face. The weight of your binocular is an important consideration. If the binocular is too heavy, not only will your shoulders get sore, but also your trembling will destabilize the image you see. Also, check the minimum focusing distance of the binocular. Some models won't focus on an object 10 to 15 feet away, which may be desirable as some birds allow close approach.
A field guide to the birds of your area is indispensable in sorting out the different bird species. There are many field guides to choose from. Some guides just list the more common species of the area or specialize in certain bird groups, e.g., waterbirds or raptors. Guides with fewer species of birds have the advantage of not overwhelming the novice with large numbers of birds, but there is nothing more frustrating than getting a good look at a beautiful bird and not being able to find it in the guide book. A comprehensive field guide such as National Geographic Society?s Field Guide to the Birds of North America (4th ed.) or The Sibley Guide to Birds (North America) may seem a bit complex at first but all the birds are there. This, of course, doesn?t mean that you will be able to identify every bird that you see.
There is a steep learning curve when identifying birds. Don't let this frustrate you. Even the expert birders can't identify every bird they see. It is a good idea to start by becoming familiar with the most common birds in your area and slowly expanding your range of bird familiarity. You will slowly learn to identify more and more birds. Begin with noting the overall size and shape of the bird, its beak shape, plumage coloration (it is important to learn the parts of the bird and locate these colors). You will also start to notice where you find them (habitat), the seasons or months that they are present, their behaviors, their sounds, and much more. These observations in turn may spark a curiosity about where they come from or are going to (migratory patterns) or if they nest in your area. Now your field guide becomes a resource for more than just identification.
The reason that most of us watch birds is because we get great pleasure from them. Nothing can drain the pleasure from a bird hike more than being lost, cold, hungry or injured. Know where you are going and plan your hike. Trail maps are very helpful. Always bring enough water and a few snacks to tide you over in case the birding is so good that you decide to stay on the trail a little longer than you expected. Always expect the unexpected when it comes to weather. Dress in layers and wear comfortable, supportive shoes. It is definitely true that a few minutes of planning and forethought can go a long way in assuring a safe and enjoyable birding experience.
A benefit of bird watching is that it tends to slow people down. Although many birds are in plain sight, there are many more that are tucked away in bushes and trees. The pace that you might set for a "normal" early morning or late afternoon (the best times to see many birds) hike would result in a dismally low bird count. A birder is quiet, slows his/her pace and focuses his/her senses. The first hint of a bird?s presence may be a sound or a slight movement at the edge of vision. And birds aren?t the whole of a birder?s experience. Heightened senses often result in our becoming aware of the natural beauty we often overlook. It would not be unusual for a birder to spend an entire morning covering a mile-long stretch of a rich habitat.
With experience you will automatically lift your binoculars into exactly the right place to spot that chickadee in the pine tree across the trail. And there will be fewer and fewer times that you will need to pull out that guidebook to make an identification of a bird. But more importantly, you will be eagerly planning your next bird adventure even before returning home from your present one. You are hooked.
