Thanks to Peter and Phil, we have a count today...
Northern Harrier - 1
Cooper's Hawk - 1
Peter was at the park for an hour mid-day and got the Coop. Phil was there on his lunch break shortly thereafter and got the Harrier. Thanks guy!
Tomorrow morning's predicted wind is N 15km/h, then N 20km/h and gusting for the afternoon. Should be good if there are still birds left.
