Description:

Foliage added, there does appear to be different types in the field as Lavaterguy guessed there might be. I think the foliage on the right in the last pic is from a buttercup, the thinner leaved ones definitely are and it seems to be the most prevalent species in the patch I was taking my photos.

I think

we'd need to see the leaves to take this to species.

Stace says that ...

... the achenes of R. acris have hooked beaks, and those of R. repens have curved beaks. But most of us find the foliage an easy means of distinguishing the two species, and haven't paid significant attention to the form of the fruits. I would say that this is R. acris, but can't be confident that I'm drawing the line between hooked and curved correctly.

Thanbks Moremoth and

Thanks Moremoth and Lavateraguy, I'll add foliage this evening, the field behind the house has been left ungrazed this year and is a rich yellow meadow thanks to these buttercups.

It's quite possible ...

... that the field has both Ranunculus acris and Ranunculus repens growing in it. The former has palmately lobed simple leaves, and the latter ternate leaves.

Thanks Lavateraguy. What

Thanks Lavateraguy. What about the leaf on the right in the final pic? Is that a typical buttercup species leaf?

Buttercup are heterophyllous ...

... that is the leaves vary according to the position on the plant, in general becoming more dissected as you go up the stem. I think that the last leaf must be a basal leaf of Ranunculus acris/

Species

There are fields in which three common species grow - Meadow, Bulbous and Creeping. Bulbous flower first and have reflexed yellow sepals, but the other two you can't tell apart from just a photo of the flowers. In your field you might still find Creeping (R. repens) in flower around the edges.
