🐦 BuildToDoGood Birding

Free tools and honest gear reviews for backyard birders, hobbyist watchers, and field-trip regulars.

Pick up binoculars. Hang a feeder. Walk a trail. The hobby is simple. The gear industry isn't. Most binocular reviews online are written by people who got the binoculars sent for free, and most "best bird feeder" lists are affiliate-link factories that haven't tested anything.

This is the opposite of that. Calculators that work on a phone in the yard. Reviews from someone who actually used the gear for a season. Regional checklists for what to look for, where, when.

Tools

Bird Feeder Seed Mix Calculator How much of each seed type to mix for the birds you want to attract. Avoids the wasteful filler-seed blends sold at chain stores. Binocular Field-of-View Comparator soon Compare magnification, FOV at 1000 yards, exit pupil, and twilight factor across binocular models. Helps you choose without trusting marketing copy. Window Strike Distance Calculator soon How far from your window to place a feeder to prevent window-strike deaths. Or how close (under 3 ft, birds can't build escape speed). Spring/Fall Migration Window by Latitude soon When to expect spring and fall passage at your latitude. Based on average eBird data.

Honest gear reviews

Coming as I test things. The first review is a comparison between three entry-level birding binoculars in the $200 range that real birders actually buy: Nikon Monarch M5 8x42, Vortex Diamondback HD 8x42, and Celestron Granite ED 8x42.

None of these companies sent me free units. I bought one and borrowed two from people in my regional birding group. The review is honest.

Regional checklists

What to watch for, where, when. Starting with the Mid-Atlantic since that's where the operator lives. Hawk Mountain hawk watch dates. Cape May fall migration timing. Bombay Hook winter waterfowl. Brandywine Creek breeding warblers.

Plain note about money: Some product links on this site are affiliate links (mostly eBay Partner Network). If you buy through them, I earn a small commission. The amount you pay doesn't change. Recommendations come from actual use, not commission rates. If a product without an affiliate program is better than ones with one, I'll say so.
