[EBB Sightings] Sharpie at Coyote Hills

...at least I think that's what it was.

Looking south from the entry kiosk, at some distance, I saw a Kestrel being harrassed by a slightly bigger raptor, with a long tail and relatively short, broad wings.
Later, near the visitor center, a quick flyby of what was likely the same bird revealed all-gray upperparts and again the long and squared-off tail.
An ancient Coyote HIlls bird list shows Sharpies as uncommon.

4-5 Gnatcatchers were chattering garrulously near the quarry prk'g lot.

Ran into Kathy Robertson, both of us looking for migrant warblers, none of which appeared to be in evidence.

Good birding!
