After 2015’s memorable 75th anniversary count a letdown seemed inevitable, and our expectations dropped further when a terrific rainstorm moved in three days prior to count day. But when owlers began “work” in Redwood Regional Park at 2:30 a.m. on Sunday, December 18, the stars were brilliantly clear. Later on, the day warmed to 54 degrees under bright sunshine, no rain fell, and the 302 participants in Oakland’s 76th Christmas Bird Count enjoyed good birds and another wonderful Oakland Christmas Bird Count.
Altogether we found 116,055 birds, some 20,000 above our recent average, and 179 species, near our recent average. Total numbers were buoyed by a record high count (since 1974) of 24,000+ Greater Scaup, with more than 14,000 of them found by our South Boat. Numbers of scaup have fluctuated greatly over the years – in the 1970s, three consecutive counts recorded 14,000+, 91,000+, and 35,000+ scaup, respectively, so the fact that this year’s total of 26,084 scaup is more than twice last year’s total does not represent a trend. The actual, highly discouraging trend is this: On average, numbers of scaup, and numbers of all duck species in total, have declined 50 percent from the 1970s to recent years.
Besides Greater Scaup, we also had record-high counts of Green-winged Teal, Least Sandpiper, Forster’s Tern, Hairy Woodpecker, Peregrine Falcon, American Crow, and Pygmy Nuthatch.

Among the notable species recorded on count day were a Snow Goose, a Brant, two Red-necked Grebes, and two Common Gallinules. A lone Cattle Egret at the Oakland Airport was likely the same bird present there last season, when it broke an eleven-year-long drought since the last Cattle Egret. It was gratifying to again find Snowy Plovers – 25 of them – present in Alameda, and 29 Surfbirds present along the Bay shoreline.
Swallows, especially Tree Swallows, are being seen in increasing numbers on Bay Area Christmas bird counts, almost certainly a sign of warmer winters. We found Tree Swallows in two areas this season; our two House Wrens and two Blue-gray Gnatcatchers may also owe their presence to warmer winters. Wilson’s Warbler, with three found on Bay Farm Island – our first since 2004 – was selected as the count’s Best Bird. Disappointingly, a male Black-headed Grosbeak spending its third winter in Claremont Canyon was not seen on count day.…
