Submit a photograph

The photographs in this guide are freely licensed and show free-living wild birds. Anyone with such a photograph can offer it here.

Each species has one main photograph and, below it, additions: the other sex, winter plumage, a young bird, a chick. A submitted photograph is considered if it shows a plumage or a stage the page still lacks, or is clearly better than what is there. The author judges every submission himself; nothing goes on the site automatically. Replies are sent by e-mail.

What a photograph must meet

Where the guide still lacks a photograph

For these species no freely licensed photograph of a living wild bird exists:

The form

JPEG or PNG, landscape, long side at least 1600 pixels, at most 20 MB. An iPhone converts a HEIC photo by itself.

Type to search by English, Dutch, Spanish or scientific name.

Only needed if the photograph itself carries no date.

As it should appear under the photograph: region, site or town. For a vulnerable breeding bird the region is enough.

This is how the name will appear under the photograph and on the sources page.

Only for replies. The address never appears on the site and is kept as long as the photograph is in the guide.

CC BY 4.0 is the lightest the guide allows: free use with attribution. The guide carries no NC or ND licences.

Optional: what the photograph shows, or why this one.

What happens with the data: the photograph is reduced to 2048 pixels and stored without the location data a camera adds. Name, place and date go with the photograph; the e-mail address does not. A photograph that is not taken up is deleted.
