Birding Alaska

The first few days at sea have been great.  Our departure from Dutch Harbor on July 21st was met with 4o knot winds and 15-20 foot seas, not the best birding conditions, even on a 209 foot ship.  Despite the conditions I was able to snap off a few marginal photos of this Mottled Petrel just north of Unimak Pass in the large swells.  Mottled Petrel is the only Pterodroma expected in Alaskan waters.  It is first picked out by its fast and arching flight and then identified by its shape, sharply patterned back and underwing, and its dingy-gray belly; it is the only Pterodroma to show this gray belly.  Normally you see Mottled Petrels for about three seconds as they flash by, however, with the very strong winds several of the birds, including the bird in these photos, cruised along side the ship for several minutes.  We saw four Mottled Petrels on the first night out and at least eight the next morning within 45 miles of Unimak Pass.

This evening, July 23rd, things got even better–even the weather!  While transiting over Zhemchug Canyon on the Bering shelf (about 180 miles west-northwest of St. Paul Island) under calm winds and seas we found two Short-tailed Albatross–a dark brown juvenile and a paler sub-adult bird.  The juvenile is photographed here.
