Credits
Every photograph here was taken by somebody else and shared under a licence that says to credit them. So here they are, in full, with a link to the original file.
Images come from Wikimedia
Commons and are copied onto this server rather than
hot-linked, so viewing this page sends no request to Wikimedia and tells
them nothing about you. They were fetched once, by
tools/fetch-ducks.py.
Each licence link goes to the licence text; each file link goes to the Commons page, which carries the full authorship history.
