Bird seed aliens

These three grasses were found not far from our garden bird feeders here in Gorseinon last week; left to right: Green Bristle-grass (Setaria viridis), Hairy Finger-grass (Digitaria sanguinalis) and Cockspur (Echinochloa crus-galli).

It's the first time I have seen Hairy Finger-grass, but the other two have regularly appeared in the garden for many years and are possibly established garden weeds. Greater Quaking-grass (Briza maxima) was also a well established garden weed, but appears to have died out over the last couple of years.
