juvenile Hobby brood

this pair had been baffling me this year; the female is totally undemonstrative and just sits on her look out perch while I walk underneath -- the male was always absent and I was beginning to wonder if they had failed this year then this morning the male flew in scolding me and the female came up to join him but then they both soared up to about 1000 feet and drifted around catching insects -- a walk around the corner of the wood suddenly revealed three juvs sitting together on a branch -- clearly a later brood and probably only fledged about a week, no sign of them ten days ago when I last checked  --
