Rare Bird Alert: September 22, 2017

This week sees vagrants continuing in western Alaska, shifting southward to St. Paul this time around. Lots of birds moving across the continent in this busiest month of fall migration means lots of wayward individuals, and this week continues the trend of a lengthy RBA we started last week. First, though, continuing rarities are getting scarce with the perhaps never leaving Tufted Flycatcher (ABA Code 5) recorded again in Arizona this week, as well as the long-staying Blue-footed Booby (4) in California.

We start again with Alaska, where exceptional birds continue in the Bering Sea outposts. On St. Paul in the Pribilofs, a Dark-sided Flycatcher (4) was a highlight, along with at least 2 Gray-streaked Flycatchers (4), a Green Sandpiper (4), a Common Rosefinch (4) and a candidate for Kamchatka Leaf-Warbler (5). In the Aleutians, another Kamchatka Leaf Warbler (5) was well-photographed, as well as a Gray-streaked Flycatcher (4) on Adak. Gambell checks in with 2 Siberian Accentors (4).
