need to zoom in to get better look, and still not great pics, in small flock on farmland, flew away quickly
No interactions present.
The photographs are not really good enough to say that these are definitely Meadows Pipits, but the streaking on th flanks is visible on at least one and looks too heavy for Tree Pipit.
The fact that they were in 'a small flock on farmland' also points strongly towards Meadow Pipit - the first migrant Tree Pipits will be turning up now (and one could join a flock of Meadow Pipits), but you are unlikely to see a flock of Tree Pipits. In general Tree Pipits aren't found on farmland either, although migrants might stop briefly on farmland as they pass through!
Using a photo enhancing on this photograph all three birds in tree appear to be, Fieldfare.
These definitely are not Fieldfare - even without considering shape and size, the lower of the two right hand birds can be seen to have pale wing bars (not a feature seen in Fieldfare).
i thought they seemed smaller in size than that..though it was just a brief glimpse.
i have enhanced your pictures and I feel they are fieldfare the only other alternative could be Redwings
The original photo when enlarged shows four birds (one bottom right seen from behind) which between them give a pretty good overview of the birds features. Whilst the photo is not clear enough to identify them to species, it is apparent that they are pipits. streaked breast and flanks, striped mantle and back, pale edges to primaries, pale supercilium, pale submoustachial stripe and pale double wingbar.
looking at a recent pipit spot u can see the similarities
These are definitely pipits, a shown by the fine streaking on the breast, double wing bar, slight build and general olive colouration. There are many Eurasian species that fit this description but in practice 99% of the pipits you see on farmland in the UK will be meadow pipits. In early April make that 99.9%.
