To me, the following features make this...Hi all,<br /> To me, the following features make this a Reed Warbler:<br />-the emargination on the third primary falls well back on the wing, more of less level with the tip of the innermost primary or even the secondary tips. This is much better for Reed than Marsh, on which the same emargination often falls level with the tip of the seventh primary, more or less.<br /><br />-the facial pattern, with the broken eyering being far and away the most obvious feature, is typical for Reed. Marsh often have a pale supraloral area...though this is not as blindingly obvious as on a classic Blyth's Reed, it certainly does give identifiable individuals a different appearance.<br /><br />-the bill seems too thin for Marsh.<br /><br />-I'd like a Marsh Warbler to have a slightly longer primary projection than this, but, of course, there is some overlap.<br /><br />-I'd also expect an identifiable Marsh Warbler to perhaps show a greater contrast between dark tertial centres and well-defined pale fringes than this bird shows.<br /><br />Also, the calls. To my ears, Reed's tacking call is reminiscent of that of a Eurasian Stonechat, with a definite 'ch' sound, 'chak', whereas Marsh (like Blyth's Reed) give a more Blackcap/Lesser Whitethroat-like 'tak'. Subtle, but they do sound different.Harryhttps://www.blogger.com/profile/04534554869387375467noreply@blogger.comtag:blogger.com,1999:blog-8891996712567136282.post-27498217051303327632012-11-01T02:23:37.032-07:002012-11-01T02:23:37.032-07:00Hi Graham, I seem to remember Killian telling me t...Hi Graham, I seem to remember Killian telling me that if the longest tertial stretched beyond the secondaries - forming a step - then it's a Marsh Warbler. HOWEVER!! I could be remembering that completely the wrong way around!! If not, this bird looks like it's a Marsh Warbler....Stevehttps://www.blogger.com/profile/04504884944694272171noreply@blogger.com
