WERNER SYKORA IS: THE BEAVER MAN

Sunday, June 6th, 2010 geschrieben von Patrick

At an ornithologist conference in may 2010 I met Werner Sykora from
Bad Düben (Saxony, Germany). He´s a guard to protect Beavers
Castor fiber in northwestern saxony and over several years he made
a lot of recordings from the  inside of beaver lodges. In addition it
seems notable that Werner is building most of his equipment by himself.
Please listen to a selection from two “Best of CD´s” he shared, and feel
free to get in contact (oberbiber at web de).

HISSING AND CLICKING

Tuesday, July 14th, 2009 geschrieben von Patrick

What do you think you hear in this recording?
A clockwork? A model railroad? Or maybe a snake?

Yesterday we ringed some juvenile Wrynecks Jynx torquilla.
What you can hear is their defense call.
For us it was a really impressive experience to hear and see
this bunch of hissing and clicking young birds in the nest-box.
This defence behaviour is optical remarkable too.
The Wrynecks turn their heads all the time to impersonate a snake.
Combined with the sound it didn´t miss its effect :-)

CORN BUNTING WITH YELLOWHAMER SONG

Sunday, August 3rd, 2008 geschrieben von Patrick

On Spring 2008 the ornithologist Reinhold Brennecke (Haldensleben, near Magdeburg, Mid-Germany)
told me about a Corn Bunting Emberiza calandra he watched for 3 years, which singing like
a Yellowhammer Emberiza citrinella. At the Forum of “Verein Sächsischer Ornithlogen” (VSO) i read
a report about the same topic. On early summer i visit the described place and had the luck to see and
hear the bird. Actually it was a Corn Bunting (on Dick Forsman´s homepage I read 1 month ago about nearly
grey Yellowhammers!)
While our SINGWARTE camp in June 2008 Marcus Held and I went out to record the singer.
The bird sang 2 different kinds of songs. A nearly equal Yellowhammer and a mixed
Yellowhammer/Corn Bunting song. The mixed one starts with Corn Bunting like short single sounds,
followed by a Yellowhammer part (typical first part double sounds in Yellowhammer song). The song
of our Corn Bunting ends with the typical short Corn Bunting sounds.

SYLVIIDAE WITH ATYPICAL SONGS

Tuesday, July 8th, 2008 geschrieben von Patrick

Last year a birder from Leipzig pointed me to 2 birds that sing atypical. They were optically identified as Sylvia borin and Sylvia atricapilla. A detailed article was published in the society´s periodical “Mitteilungen des Ornithologischen Vereins zu Leipzig e.V. #14″. Please find the recordings and sonagrams below:
