During a stay at the western coast of Sri Lanka, bird-lens.com shot images of an alleged Acrocephalus-Warbler in Briefs Garden, an ornamental garden near the west coast. Immediately I was thinking of a Blyth’s Reed-Warbler (Acrocephalus dumetorum) but could not really confirm ID not at least because the habitat – a garden hedge – was quite strange for the species. I asked for ID-advice from the experts in birdforum.net. Some agreed with BRW (as Blyth’s Reed-Warbler is abbreviated) others voted for a Sykes’s Warbler (Iduna rama) due to the proportions, the long, unrounded tail, the general hue of the plumage, the colour of the legs. Sykes’s Warbler is sometimes regarded as a subspecies of the Booted Warbler (Iduna or Hippolais caligata rama) is a plain brown warbler with pale legs. The bird breeds in Central Asia and winters primarily in India but also as far south as Sri Lanka. The close relative of Booted Warbler prefers trees with sparse canopy in open, dry habitat. Both time when observed in dense Mangrove-like bushes in Sri Lanka, the first thinking of this brown bird with a pointed forehead was of an Acrocephalus – warbler.
And in deed, this small Hippolais – Warbler with its quite long, thin, pointed bill, flat forehead and crown, and rather long tail enhanced by short primary projection often resembles an Acrocephalus – Warbler.
Während eines Aufenthalts an der Westküste Sri Lankas schoss bird-lens.com Bilder von einem mutmaßlichen Acrocephalus-Rohrsänger im Briefs Garden, einem Ziergarten in der Nähe der Westküste. Sofort dachte ich an einen Buschrohrsänger (Acrocephalus dumetorum), konnte aber die Art nicht wirklich bestätigen. Das lag nicht zuletzt daran, dass der Lebensraum – eine Gartenhecke – für die Art recht seltsam erschien. bird-lens.com hat dann die Experten von birdforum.net um Rat gefragt. Einige hielten den Vogel für einen BRW (wie der Buschrohrsänger aufgrund seines englischen Namens Blyth’s Reed-Warbler abgekürzt wird), andere sahen einen Steppenspötter (Iduna rama) auf den Bildern. Die Proportionen des abgebildeten Vogels, der lange, ungerundete Schwanz, der allgemeine Farbtons des Gefieders und der Farbe der Beine würden eher für den Steppenspötter sprechen. Der Steppenspötter wird manchmal taxonomisch auch als Unterart des Buschspötters (Iduna oder Hippolais caligata rama) angesehen. Es handelt sich um einen Continue reading Steppenspötter oder Buschrohrsänger in Sri Lanka?→
During a trip from October 08th till 13th 2012 to experience migrating birds on Helgoland several remarkable sighting could be noted. A Booted Warbler, Hippolais caligata, was seen at the red sandstone cliff at the southern corner of Helgoland, at the so-called “Kringel” on the 9th of October 2012. On the same day a Siberian Stonechat, Saxicola maura, was seen in the area near the sports field and a Rosy Starling, Pastor (Sturnus) roseus, was seen in the Kurpark. Further remarkable sightingson that day was a Barred Warbler, Turtle Dove, a Wryneck and the Yellow-browed Warbler.
Although the Booted Warbler thrilled the many birdwatchers already, that feeling could be even increased. On the following day, a strange thrush could be observed. Short ID-discussion revealed a Turdus atrogularis, a Black-throated Thrush, a recent split from the Dark-throated Thrush, Turdus ruficollis. The bird showed only for a few moments and disappeared for more than 2 hours. In the evening – just before dusk – it was seen briefly again. The lucky few were happy but the many frustrated birders who did not see it expected that the birds will leave in the night. This due to the fact, that a calm night with low wind was forecasted. It was a happy surprise, that on the following days until – at least – the 15th of October the the thrush showed up again – albeit with long times in between suddenly appearing on the steep slope just below a place called Falm on the so-called Oberland.
