RAS RESEARCH COMMON COOT (Fulica atra)

In 1998 in the context of the RAS-project I fitted Common Coots with a metal ring in the city parks in Arnhem. The ringing work is concentrated in the parks of Sonsbeek and Angerenstein. In total there are tens of breeding pairs. The birds are baited by feeding with bread. At the same time the metal rings are read using a telescope.
From every successful brood normally only (1-4) young become fledglings. But many breeding attempts and second broods do increase the number of young.

The low number of recoveries in the years 2004 and 2005 is erroneous and is caused by a backlog with data entry of these observations.

Numbers of Common Coots with a ring:

Year Young Adult Adults returned from earlier years
1998 1 1 0

1999 0 23 1

2000 7 6 18

2001 20 15 22

2001 20 15 22

2002 9 8 42

2003 2 7 24

2004 10 6 17

2005 11 10 18

2006 2 10 11

2007 17 23 28

2008 24 18 49

2009 8 10 54

2010 27 31 56

Total 138 168

Sometimes Common Coots are so tame, that they can be caught by hand, here by Frank Majoor.
