If like to write shortform (150 words plus pic) @TheDailyCuppa also has a very engaged audience (so much so that at times it stops accepting new writers briefly) and a kind, helpful, and fast-publishing editor, @KatieMichaelson. You can tell her I recommended you as a writer if you might like to write for it.
Your can post photos at The Daily Cuppa what what is essentially a long caption: e.g., a photo + why you find a certain bird interesting. So many essays at Medium go on and on, a lot of people appreciate brevity.
