from a journal kept by Gerard Manley Hopkins, English Jesuit teacher and poet, 1844-1889, quoted by Hannah Hinchman in A Trail Through Leaves. She is giving suggestions about how to write vivid descriptions of the natural world.
They look like little gay juds by shape when they walk, strutting and jud-judding with their heads. The two young ones are all white and the pins of the folded wings, quill over pleated quill, are like crisp and shapely cuttleshells found on the shore. The others are dull thundercolour, or black-grape-colour, except in the white pieings, the quills and tail, and in the shot of the neck. I saw one up on the eves of the roof: as it moved its head a crush of satin green came and went, a wet or soft flaming of the light.
