About

Welcome to Birds-in-flight, our work-in-progress website
dedicated to audiovisual identification of birds on migration.

The focus of our collection is on western palearctic species
plus some eastern eurasian species with vagrancy potential
for comparison.

As freelance ornithologists we find us regularly confronted
with the identification of birds in flight – mostly far away, in
high altitudes, poor light, stiff wind – providing just a few
key features or key parts of there vocalisations.

Beside a general interest for annual animal movements that
problem turned into a passion (our friends and partners
would most likely say obsession) and we would like to share
our enthusiasm and accumulated knowledge with other
serious birders.

Our knowledge is based on own field observations but in
equal parts on literature, drawings, websites, sound recordings,
photographs of others.

We would like to thank our mentors and people who have
shared their knowledge in the field and fruitful discussions:

Andreas Buchheim, Simone Grüttner, Jens Halbauer,
Thomas Hallfarth, Wieland Heim, Marcus Held, Steffen
Koschkar, Peter Nuyten, Magnus Robb, Thomas Sacher,
Michael Schulz, Arnoud van den Berg, Jan von Rönn
and Arend Wassink

In particular we would like to thank our partners, families and
friends for their support and patience!
