# Bird of the Day
> A new bird species every day with photography, facts, and a link to eBird.
Every time you open a new tab, BirdTab displays a different bird species. The bird changes once per day — multiple tabs on the same day all show the same bird.
## What's shown
Common name prominently displayed, scientific name in italics beneath it.
Full-screen landscape photography from the Macaulay Library at Cornell Lab of Ornithology.
A short description of the species, its habitat, and behaviour.
Where the specific photo was taken in the field.
Photographer name, linked back to the original Macaulay Library asset.
Click the bird's name or eBird icon to open the full species page.
## Refreshing the bird
Click the **refresh button** (circular arrow) in the toolbar to load a different bird immediately, without waiting for the next day. This draws a new random bird from your selected region.
## How birds are selected
Birds are drawn from a pool of species relevant to your selected region. Each day a new bird is picked randomly from that pool. The next day's bird preloads in the background so new tabs open instantly.
By default BirdTab shows birds from **North America**. Pro users can choose from 200+ regions worldwide. See [International Regions](/pro/regions).
## Data source
All photography, audio, and video comes from the **[Macaulay Library](https://www.macaulaylibrary.org/)** at the Cornell Lab of Ornithology — the world's largest scientific archive of wildlife recordings. BirdTab requests landscape-oriented photos for the best full-screen display.
## If something goes wrong
If BirdTab can't load bird data and has no cached backup, it shows an error with options to **Try Again** or **Send Feedback**. In most cases a cached bird from a previous session loads as a fallback automatically.
