"A bird a day keeps the doldrums away." That line opens a 2017 Audubon magazine piece on one of the simplest games in birding: try to find a new species every day, and keep the run alive as long as you can. Birdaday Field Notes is an independent, sourced reference built around that idea. It explains the challenge, gives you a free tracker to play it, and collects the backyard basics (feeders, food, nest boxes, identification) that make a long streak possible.
What is the Bird-a-Day challenge?
The rules are short. You log one bird species per day. In the words of Audubon contributing editor Rene Ebersole, who played it publicly in 2011, "The goal is never to repeat a species, nor to go a day without seeing a new one." Early on it is easy: the first days of the year let you pick from everything at your feeder. The hard part comes weeks later, once the common birds are spent and you have to go looking.
Audubon says most people don't last a month or two, and only a rare few keep going past six months. Ebersole's 2012 run ended with a Rock Pigeon on April 1, Day 92. In 2015 a field-naturalist newsletter in Victoria, Australia, reported that a retired Australian couple were the only birders worldwide to see a bird a day for the whole of 2014.
There used to be an online version of the game at this address. Audubon pointed readers to birdaday.net as an "online competition" where you could "log your daily observations in a public forum." Tropical Audubon Society says that site was created by Trey Mitchell, a Miami software developer and nature photographer, so that "birders from all over the world could post and share their observations." Mitchell died unexpectedly in November 2017. This site is not connected to his project. We only document the idea he helped popularize, using published sources.

Start today: the free streak tracker
Our Bird-a-Day streak tracker runs in your browser. Type the species you found today. It flags repeats, counts your streak, and shows the day number. Nothing is uploaded. If your browser allows local storage, your list is saved on your device only.
Backyard guides
A long streak is built on knowing your yard. These reference pages pull their numbers from the Cornell Lab of Ornithology, National Audubon Society, the Smithsonian and university extension services:
How to use this site for a streak
- Days 1–14: spend your rarities, not your regulars. Audubon says to "always note the most unusual species you see" and to save reliable feeder birds for hard days.
- Build a backyard bank. A stocked feeder, a clean birdbath and a nest box add species you can count on. The feeding table shows which food brings which birds.
- Plan by season. Winter favors waterfowl, spring brings songbirds, summer suits shorebirds and fall brings raptors. Check eBird bar charts for your county to see when each species is usually reported.
- Learn the common ones cold. Most streaks end on a busy day, not a slow one. Being able to name a chickadee by its call in five seconds keeps you in the game. Start with the ID basics.
Whether you last nine days or the full year, the payoff is the same one Audubon describes: the habit of scanning your surroundings, and learning when and where birds show up.
