Jackson Bottom birds: March 27 to April 2, 2010



New migrants this week included NORTHERN ROUGH-WINGED SWALLOWS and numerous CLIFF SWALLOWS on March 29, but not thereafter. An OSPREY was observed March 31. High water forced a SORA into view for photographs on April 1.

Some other migrants that arrived earlier this spring, increased in numbers during the week, especially VIOLET-GREEN SWALLOWS, RUFOUS HUMMINGBIRDS, CINNAMON TEAL, and GREATER YELLOWLEGS.

A PILEATED WOODPECKER was reported during the week, a rare visitor. A drake EURASIAN WIGEON was present March 29 and April 1. It may be the same one reported off and on in the area for several weeks now. A WHITE-THROATED SPARROW put in an appearance at the front feeders on April 2.

Flocks of RIDGWAY’S CACKLING GEESE arrived in large numbers during the week, adding to the TAVERNER’S CACKLING GEESE that wintered, along with the resident WESTERN CANADA GEESE and wintering DUSKY and LESSER CANADA GEESE. If one wants to practice their white-cheeked goose identification, now is the time!

Several different BALD EAGLES were seen, some attacking the resident pair on their nest!

A pair of RED-TAILED HAWKS are nesting in Owl Woods, the grove of Douglas-firs on the southeast side of the Preserve, that also contains several GREAT BLUE HERON nests.

  1. Are Ridgway's Cackling Geese the minima subspecies? (Cackling Cackling Goose)

  2. Yes, John, that is correct. So confusing that they would name Branta canadensis hutchinsii the "Cackling Goose" (Branta hutchinsii) when Cackling Goose was already in use for Branta canadensis minima. I bet this changes in the future....
