@fractalkitty Swans come to mind for thematic reasons. Some of my favourite local birds are the Eurasian sparrow (wonderful iridescent sheen), the common kingfisher (flash of green-blue and orange) and the Eurasian jay (with a small patch of patterned blue).

@SylviaFysica oh wonderful! I am going to contemplate these. Swans could be sooooo fun :)
