(22 July) 1245 J537 or/M arrives, displaces J538 from acorn, a reasonable dominance interaction a few very mild pecks.
J don!
23 July Start 0650. 2 very young-looking juvs & an adult up in the RD Hill sap trees. 0730. J537 pecks hard at J617 Red-DBlue/LPink 3 separate times while being fed by F265 One more time a few moments later 0830, Coopers Hawk everybody heads for holes. couldn't see who gave the alarm calls

0840, J537 gives a few gentle pecks to J539, ad feeding.
J539 shows some tentative signs of molting into F, as I think I see some dark feathers on "her" forewing after 0840, worried about J617. 0930, both Jul 538 + J539 peck at J617 as still all begging from adult.
That would complete dominance table if J618 did not fledge, as I suspect he did not. Will keep an eye on molt status of these guys. Will check nest later today (?)
Nest check at 1630, nest empty. No dead baby, so J618 must have made it out. Where is he?
24 July A quick watch here, still don't see J618 (0810-0845) so it looks bad for him. Nonetheless, only saw F265 O184, J538, J537.
29 July Start 0800 840 a perfect series among the new juvs.
