Unidentified bird call

[jeremiah]

This was at Pulborough Brooks last week.
Something (I presume a bird) was circling close by making a repeated sound:

"prrr prrr prrr" then a pause then "prrr prrr prrr" again several times over. I could not spot it.

This was about 4pm, by the cow pasture next to the "adder alley".

Does anybody know what it could be?

Maybe a Turtle Dove- they make a lovely purring sound. Always difficult to ID sounds from a written word.

Thanks for the suggestion Aeshna.

Yes, it could have been a turtle dove - it sounded more like the RSPB recording than the Xeno canto ones, except for the "rhythm" of the calls - they were definitely in threes.
