Booted Warbler and other vagrants on Helgoland

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 sightings on 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.

Thus an excellent bird sighting for Continue reading Booted Warbler and other vagrants on Helgoland

Great Grey Shrike, Lanius excubitor on Helgoland

During a trip in the 1st half of October 2012 to experience migrating birds on Helgoland several remarkable sighting could be noted. Just one sighting very short. A beautiful Great Grey Shrike, Lanius excubitor, could be seen in perfect light in the afternoon of the 13th of October in the area of the former Suedhafen (southern harbor) of the tiny offshore island of Helgoland in the Northern Sea, roughly 50 km out of sea from the shores of Friesland. Later on there were seen 2 more individuals on that day. On the next days, Sunday, the 14th and Monday, the 15th of October only 1 Great Grey Shrike could be seen on Helgoland.

This was the first sighting for the fall migration. The last observation of the Great Grey Shrike has been on the 17th of April on that island. Although not a regular sighting on Helgoland, the Great Grey Shrike does not qualify to be rare enough to be listed in the category “Rare birds – day by day” as you can see on the superb website of the Ornithologische Arbeitsgemeinschaft Helgoland e.V. (OAG)

In his „Handbuch der Vögel Mitteleuropas“, Band 13/II „Passeriformes, Sittidae – Laniidae“ Urs N. Glutz von Blotzheim mentioned that migration of the Great Grey Shrike, Lanius excubitor, (also called Northern Shrike), at the coast Continue reading Great Grey Shrike, Lanius excubitor on Helgoland
