About Birdiy
America’s guide to identifying, attracting and enjoying wild birds — built around free tools that answer your question in seconds.
Birdiy is an independent US birding resource. We publish species guides, backyard how-tos and free interactive tools — nectar calculators, feeder timing by state, birdhouse dimensions — so you get a specific answer for your yard instead of a generic article.
Our mission
Most birding questions have a precise answer that depends on where you live, which species you’re dealing with and what equipment you own. “How much sugar goes in my feeder?” depends on your feeder size. “When do I take the feeder down?” depends on your state. Yet most of the internet answers those questions with a paragraph and a shrug.
We built Birdiy to close that gap. Every guide we publish aims to be the clearest explanation available, and every tool we build turns a general rule into your specific number.

Birdiy earns money in two ways, and we’d rather tell you plainly than bury it.
Advertising. We show ads on some pages. Advertisers have no influence over what we write or which products we recommend.
Affiliate links. As an Amazon Associate we earn from qualifying purchases. If you buy through one of our links, we may receive a small commission at no extra cost to you. We only link to products we would suggest to a friend, and a product never appears here because someone paid for the placement. Read our full affiliate disclosure.
Our bird-welfare rule. Where advice affects a bird’s health — nectar ratios, feeder hygiene, birdhouse hole sizes, when to stop feeding — we follow the guidance of established ornithology and wildlife organisations, not whatever makes for a better sales pitch. That’s why we tell you never to use honey or red dye, even though plain white sugar is the cheapest thing in the recipe.
Who writes Birdiy
Birdiy is a small, independent team of backyard birders based in the United States. We’re not a research institution, and we don’t pretend to be. When a question needs an expert answer, we cite the organisations that have done the fieldwork, and we tell you when the science is uncertain or when local conditions change the answer.
Start with the tool most people need first — the exact nectar recipe for your feeder size.
