261 V O L U M E 7 0 ( 2 0 1 9 ) • N U M B E R S 3 / 4 RED-BACKED SHRIKE IN ALASKA Figures 11A–D. Typical juvenile or first-fall Turkestan Shrikes (A, Khazakstan, 18 June 2013; and B, Israel, September 2014) and Red-backed Shrikes (C, Bulgaria, 22 September 2004; and D, South Korea, 30 September 2009). Note the much grayer backs of the Turkestan Shrikes, lacking contrast with the nape and crown but including a distinct contrast with the redder tail. Red-backed Shrikes, by contrast, show a slightly grayer nape, contrasting with the crown and back, but show little contrast between the back and tail. Note also the less distinct dark vermiculations to the back and the lack of reddish in the auriculars of the juvenile and first-fall Turkestan Shrikes, at odds with typical Red-backed Shrikes and the Gambell bird.
