Nice mate .As an inexperienced falconer many moons ago I used to exercise the Harris hawk all year round instead of putting him up to moult and you’ve guessed it ,he flew into a rookery where carnage ensued .Had his brancher and ate what he wanted and was ready to come down 6 hours later .The rooks had a mad flurry to start with but when he’d eaten his fill and was rested they left him to one end apart from odd fly over .The bird was almost bomb proof and wanted corvids with a passion from that day til I sold him .Did a lot in building near Bristol where jackdaws were shut in at night .Lampi
