Subspecies of Brown Shrike

on 10th December 2016

“My wife, a keen bird watcher for more than 30 years, has occasionally commented how variable and confusing the Brown Shrikes are. The Brown Shrike (Lanius cristatus), is said to have 4 subspecies. I have posted in this in the past and now revisiting the area. I will focus on the adult male plumage, especially head and mantel, and attempt to show some examples. Appreciate any comments, corrections and suggestions. I have numerous images I have not posted to OBI in the past.

L. c. cristatus (above): the nominate race; the migratory range is quoted as ‘C & S India, Sri Lanka, Bangladesh, Myanmar (mainly coast) and Malay Peninsula’. Duller rufous brown cap and mantel (duller russet-brown upperparts); underparts more buff; broad white supercilious. Photographed on 22nd October 2014, note that this common Brown Shrike lacks clear white throat.

L. c. superciliosus (above, below): the migratory range is quoted as ‘mainly coastal S China, Hainan, NE & E Indochina, Sumatra, Java and W Lesser Sundas’. Brighter rufous rich cap and mantel; breast and flanks orange cinnamon; wider white band on forehead, broad white supercilious. Photographed on 20th April 2014, this very brightly coloured bird (minimal editing) has bright breast and cap.

L. c. confusus (below): the migratory range is quoted as ‘S Malay Peninsula and Sumatra’. Similar to L.c. cristatus but paler.“ Photographed on 15th February 2014, there is confusion here; does not fit any of them. Light cap but not grey. No clear supercilium. Brown upper parts. Possible L. c. confuses?
