The common kestrel requires the equivalent of 4–8 voles a day, depending on energy expenditure (time of the year, amount of hovering, etc.). They have been known to catch several voles in succession and cache some for later consumption. An individual nestling consumes on average 4.2 g/h, equivalent to 67.8 g/d (3–4 voles per day).
