juvenile Hobby prey

this juv Hobby was catching insect prey over the edge of a plantation and an adjacent stubble field with a rough grass fringe -- I think this is a hornet? seems about the right size and colour although the pics are a bit small -- was surprised to see in a recent note in BB (by Dean N) that Hornet had not been recorded as prey of Hobby as they surely take them ? Hornets are increasing rapidly around N Lincs; had not seen one round here until 2006
