How we research and test

This page explains how Feeder Field reaches a recommendation, and exactly what we do and do not claim.

Where we are today: research-based

At the moment our recommendations are research-based. We have not yet tested products hands-on, and no article on this site says otherwise. For each guide we combine three kinds of evidence:

1. Manufacturer specifications. Capacity, materials, port and perch design, heater wattage, camera resolution, battery and solar details, subscription terms, optical specs such as magnification, objective size and field of view. We read the product documentation rather than relying on retailer summaries.
2. Verified owner feedback patterns. We look for problems and strengths that come up again and again in reviews from verified buyers over months of use, such as squirrels defeating a “squirrel-proof” mechanism, heaters failing in the second winter, or camera feeders losing Wi-Fi. We report patterns, not single anecdotes, and we never present an owner’s experience as our own.
3. Expert sources on birds and bird care. The Cornell Lab of Ornithology (All About Birds and eBird), the National Audubon Society and university cooperative extension services. We use them for questions such as which foods suit which species, how often to clean feeders and baths, safe birdhouse dimensions and regional ranges.

We then explain who each product suits, who should skip it, and what the trade-offs are.

What the “Researched” and “Tested” labels mean

Every article shows a label next to the author’s name:

• Researched: based on manufacturer specs, verified owner feedback patterns and expert sources. We have not used the product ourselves. This is the label on every article today.
• Tested: we bought the product and used it ourselves, and the article describes what we did and measured.

We never claim hands-on testing that did not happen.

What is coming: hands-on testing

We plan to add hands-on testing for selected products, starting with smart camera feeders and binoculars, where using the product tells you things specifications cannot. When we test, we plan to buy products at retail with our own money, use them in a backyard setting over several weeks, and report what we measured, for example identification accuracy, battery life and Wi-Fi range for camera feeders.

When a product has been tested, we will update its page, change the label from “Researched” to “Tested”, describe the test conditions, and update this page to match. Until then, the label stays “Researched”.

Ratings

If a review gives a score, it is our own editorial assessment on a 1 to 5 scale, based on the evidence above. It is not an average of customer ratings.

Keeping guides current

Buying guides are reviewed at least every six months, and sooner when products, prices or subscription terms change. Each article shows when it was last updated. See our editorial policy for the full standards and how to report a mistake.
