The binocular is the traditional heart of the birder’s optical kit. However, the popularity of the spotting scope is growing for birders who are serious about getting closer to the action. At first glance, the spotting scope may look like a telescope, but it is more closely related to a monocular due to its image-
While some telescopes can be used to make terrestrial observations with the addition of specialized accessories, most will have optics and coatings specially designed for celestial viewing, so the viewing experience has the potential to be slightly off—especially where colors and resolution are concerned. The spotting scope—its optics, optical coatings, and housing—is designed, from the start, to be a terrestrial viewing instrument.
This does not mean that you cannot admire the moon, stars, or planets with a spotting scope; it just may not present an image quite as good as a purpose-
Details are the key for Walker Golder, Deputy Director of Audubon North Carolina, who uses the office’s Swarovski, Vortex, Kowa, and Nikon spotting scopes to read “bands on tiny shore birds and terns.” These coastal birds may only be three or four inches tall, and the leg bands, placed on the bird’s tarsus, might measure only half an inch.
All that magnification means that handholding the device is nearly impossible, so taking a spotting scope into the field means taking a tripod and tripod head (or alternative support) into the field with you—a big consideration when it comes to how far from home, or your vehicle, you will be setting up. Also, binoculars may be lifted a few inches from your chest to your face for a quick observation. The spotting scope needs to be set up.
Spotting scopes are not often very heavy and, therefore, do not require large tripods. But, you do want to get a tripod that reaches a comfortable height for extended viewing while being heavy enough to provide needed stability for your scope. For birding, a fluid tripod head, popular for use with video cameras, works fantastically with a birding scope. When asked for spotting scope advice for beginning birders, Patrick Comins, Director of Bird Conservation at the Audubon Society’s Connecticut office, and President of the Friends of the Silvio O. Conte National Fish and Wildlife Refuge, says simply, “Get a good tripod.”
Straight versus Angled
Spotting scopes come in two general configurations—straight viewing and angled viewing. The difference is at the rear of the scope, where the erecting prism directs the light path straight in line with the body, or at an angle, typically 45 degrees, to the body. The straight or angled configuration is one of the first considerations that a birder must evaluate when buying a spotting scope. In general, users, especially beginner birders, find it is easier to acquire and track birds with a straight scope, but the angled scope offers more viewing comfort.
Chris Wood, experienced birder and Project Leader at Cornell Lab of Ornithology’s eBird program, spoke to us about considerations when choosing one configuration over another: “Passion can abound on the question of straight versus angled scopes. The best reason for straight is usually that it’s more intuitive to find the bird. If you bird from your car and want to use a scope, straight scopes are also easier to use.
“If you are birding with others, you almost certainly want to use an angled scope, which makes it much easier for people of different heights to use the same scope. The other advantage is that you don’t need to raise the scope as high, which means that the wind isn’t as likely to shake the scope. In most cases, people are more pleased with an angled scope after a week or two of use. It may take a little longer to get started, particularly if you have used a straight scope for your entire life. But your short friends will thank you.
“With practice, anyone should be able to find birds just as easily with either straight or angled scope.”
Bill Stewart, adds, “The only people I know [who] use straight [spotting scopes] owned them before the popularity of angled [scopes].” He uses an angled-
To give the best of both worlds, Swarovski’s latest modular spotting scopes can adapt an angled or straight-
Walker Golder notes that, with an angled scope, the tripod can set lower than when using a straight viewing scope. As he is often “getting in and out of boats,” this has time-
