Podrobnosti k pozorování
1st Aleutians record, 3rd North American. The overall rusty brown mantle with contrasting grayish nape and similar colored tail can exclude unreported Turkestan and Isabelline Shrikes. Red-backed Shrike is and has most often been confused with the expected western Alaska vagrant Brown Shrike. Features that support Red-backed Shrike over Brown Shrike include: -Grayish wash to the nape that contrasts with the rusty brown back. Brown Shrike would show a more uniform brownish color throughout the mantle, nape, and crown. -A mostly straight and fleshy-horn lower mandible. Brown Shrike would show a slightly more convex lower mandible. -A less distinct mask with rusty tones and little dark color in the lores. Brown Shrike usually has a bolder mask without rusty tones and a darker lores. -A pale whitish color to the undersides. Juvenile Brown Shrikes would show a more light buffy wash on the undersides. -A pale whitish edge to r6. Brown Shrike would have a thinner or buffy or brown edge to r6. -R6 being only slightly shorter than the rest of the tail causing the tail to look more square. R6 in Brown Shrikes would be noticeably shorter causing the tail to look more rounded. Bird was first seen landing on top of the bluff above the burn pit on north beach road between Connie Lake and 50 Caliber Beach. The bird was active and flying between the burn pit, Queens Match, and Connie Lake before it disappeared. *Many more photos were taken of this bird on 9/17 to show each of these features better than the more fleeting views on 9/10.
