List of Suggested Field Gear

All-season personal equipment:

  • FULL RAIN GEAR (I recommend PVC pants/jacket rather than Gore-tex type rain gear, although Gore-tex is great for warmer weather outings)
  • Knee-high rubber boots (Muck-type boots or LaCrosse-type boots)
  • Hiking boots with ankle support
  • Field pants (e.g., canvas type pants, students enjoy Carhart-type pants)

 General supplies:

  • Day pack
  • A field notebook (preferably a Rite-in-the-Rain type of notebook)
  • Water bottle
  • Small knife/multi-tool (Leatherman-type)
  • Clipboard
  • Flashlight/headlamp
  • Binoculars (8×40 are preferred for wildlife observations)
  • Sighting compass with declination adjustment
  • Camera

 For winter months:

  • Warm clothes (e.g., field pants, wool sweater, fleece jacket, hat)
  • Winter parka
  • Insulated boots (e.g., Sorel type)
  • Thermal underwear
  • Gloves or mittens (mittens will keep your hands warmer)
  • Small first aid kit (band-aids, etc.)
  • Ski pants or wind-breaking shell-type pants or wool pants
  • Heavy socks (preferably synthetic)
  • Synthetic or wool thermal underwear (pants and shirt)
  • Face mask or scarf
  • Hand/toe warmer

Binocular Basics

by Matt Pelikan

[from A Bird’s-Eye View, August 1998 Beginning Birding Special Issue]

Along with a field guide, a binocular is about the only piece of equipment a birder needs. Any binocular is better than no binocular — but some models are better for birding than others.

Power and size: Binoculars are usually described with two numbers: “8 x 40, 10 x 42.� The first number is how many times the binocular magnifies what you’re looking at. The second number is the diameter, in millimeters, of the large “objective� lenses through which light enters the binocular. Most birders use 7x, 8x, or 10x binoculars; which you choose is a matter of personal preference. Higher-power pairs are hard to use in the field, and lower-power models don’t provide enough magnification. Birding binoculars usually have lenses between 30 and 50 mm; binocs larger than that are very heavy, and smaller ones don’t admit enough light to work well in twilight conditions.

Field of view: This term refers to how wide an area you see when you look through a binocular. It is usually expressed as a field width at 1,000 yards, although some manufacturers describe the field of view as an angle. The wider the field of view, the easier it is to scan a large area or to follow a flying bird.

Roof and Porro prisms are the two basic designs of binoculars. Roof-prisms have the eyepieces and the objective lenses in a straight line; this design is more compact than the hipped porro-prism models, which have objective lenses spaced farther apart than the eye-pieces. Roof-prisms tend to be more rugged than porro-prisms of the same quality, but they are also usually more expensive. In a given price range, porro-prisms often give slightly better optical performance.

Eye relief is a measure of how far away from the binocular’s eye-piece your eye needs to be. This distance is usually given in millimeters; depending on the binocular it may be from 8 mm up to 24 mm or even more. Longer eye-relief makes binoculars easier and more comfortable to use, and is especially important if you wear eye-glasses.

Size and fit: It’s important to buy a pair of binoculars that feels comfortable when you use and carry it. If possible, you try out a model in the field before you purchase it. Most birders avoid pocket-sized “compact� binoculars, but for young birders with little money and small hands, a pair of compacts may be a good option. At the other extreme very large binoculars may be too awkward to carry for a full day of birding.

Price: As with most things, you get what you pay for with binoculars. Most cheap binoculars (less than $80) simply don’t work well enough to do the job in the field. At the other extreme, some models cost around a thousand dollars. These are incredibly rugged and give amazing, sharp images — but few beginners are able or willing to pay that much. Many beginning birders spend between $100 and $250 for their first pair; if you shop around, you can find binoculars in this price range that will serve you well.
