Is this a Dunnock?

Observation - Is this a Dunnock? - UK and Ireland. Description: One brown bird among the various brown sparrows and a similar size but which I think is actually a Dunnock. Tends to hide in the undergrowth below the feeder but it came out onto the grass long enough to get some shots today.
