(20 April) I think, be Unrks rather than the more common Garrick. If so, this is the first time I've been able to distinguish them. However, I think that Unrks may be quite uncommon). 868 continued to Unrke for a minute until the ♀ returned, at which point he greeted her and then flew off himself. 1135. 868 and 9265 here again.
1155. Nobody here now. All quiet. Leaving.

1107. ☺♀ M/Bk-wm#184.
1103. ! 4 birds here: ♂184, ♀, ⚫♀M/wm-Ds#269, 4th bird. All the young aren't gone after all.
1108. In sycamore across the creek: ⚫♀DB/wm-LB#265.

Quite a surprise! Obviously there are either more birds than I thought still here (possibly spending most of their time elsewhere [P.O.Hill?] and returning only to roost?) or something very strange and unheard of is happening.
