A lot depends if a raptor is prospecting for an easy meal, not really driven with urgency to feed young or hunger its self. On some of the figures quoted it would be impossible for a raptor to maintain its body condition and energy levels or blood sugars, never mind having to catch enough to keep a brooding female going with young chicks. An "experienced" raptor prospecting for a easy meal and taking a half hearted attempt, is not to be mistaken with one that needs.
