As you can see I'm still in winter mode. It's ffffreezing here despite being the 2nd March. Swarm is the theme for Illustration Friday this week and I always thought it was only used for insects, however looking it up on wikipedia - it says 'collective behaviour exhibited by animals of similar size which aggregate together, perhaps milling about the same spot or perhaps moving en masse or migrating in some direction'.
I took a photo on a frosty Boxing day morning of geese flying through the early morning sky which inspired this illustration.
