Short abstract from the book: The coal tit is a common breeding bird all over Denmark, and
a common passage migrant and winter visitor. In Denmark
the first coal tit was ringed in 1919, with most ringed during
an irruption in 1988. Most of the recovered birds were ringed in Blåvand in western Jutland and in Grib Skov in
northern Zealand. The majority were ringed in May–June
and September–October. The Danish coal tits are residents
and the mean distance between ringing and recovery site of 65
Danish birds was only 2 km. Birds ringed as chicks have on
average travelled a little further than those ringed as adults in
the breeding season. All birds that have migrated considerable
distances were ringed at Blåvand. Denmark has been visited
by coal tits from Norway, Sweden, Finland and Estonia
outside the breeding season. Most of these birds were ringed
during migration, and might be from breeding areas further
northeast. The migrants were recovered from 22 September
to 17 May, most in December.
