At the Yamhill Sewer Ponds mid-day a pair of Harriers were chasing away a Red-tail.  Mostly there were dives and feints.  The Red-tail did not seem to be in a hurry to move away, circling toward the south, then reversing and heading slowly northward. The attacking Harrier is far more agile and faster than the bigger buteo.  Most of these dives and sorties by the female Harrier seemed more formal protocol than actual attempts to do damage. It also indicates the Harrier pair are likely nesting somewhere just west of the sewer ponds.  HAR-RTH1 HAR-RTH2 HAR-RTH3 HAR-RTH4 HAR-RTH5harr-rth attack1harr-rth attack2 HAR-RTH6 RTH PROFIL

There were more species of ducks in the ponds than I have seen previously, eight.  One of species not usually present: American Wigeons.
