August 1st – One of the less obvious food sources for smaller birds like goldfinches are the wind-borne seeds of dandelions, ragwort, thistle and here, rosebay willowherb. Growing like buddleia in any urban setting where there’s a scrap of extractable nutrition, this prolific weed has gorgeous pink flowers and produces huge amounts of fluff, containing its seeds.

Small birds will spend ages on seedbeds picking out the tiny black seeds and gorging upon them. It’s fascinating to watch, and these are an excellent source of nutrition.

Everything has a purpose in nature.
