The previous week of subfreezing weather in Hillsboro, Oregon, gave way to rain and highs to 50 degrees F. The Tualatin River began backing up Jackson Slough and filling the wetlands.
Ducks came back to the thawed ponds, with many RING-NECKED DUCKS and LESSER SCAUPS on Pintail Pond.
A RED-BREASTED SAPSUCKER was found, a rare visitor that has been seen off and on for 3 weeks now near the Education Center. The male Anna's Hummingbird has not been seen since the freeze, but might still be around the bioswales in front of the Jackson Bottom Wetlands Preserve Education Center or the Cleanwater Services building next door.
COOPER'S and SHARP-SHINNED HAWKS have been reported regularly. A RED-SHOULDERED HAWK remains from earlier in the fall. A PEREGINE FALCON put in a showing during the week. Bird feeders have been put in and they are attracting many birds now.
