Short abstract from the book: The house sparrow is a common breeding bird all over the
country, from city centres to rural farmland. In Denmark
the first house sparrow was ringed in 1899, with most ringed
in the first half of the 1970s. The recovered house sparrows
were ringed all over the country and throughout the year,
most in July. Tree birds ringed abroad have been recovered in
Denmark. The recoveries show that Danish house sparrows
are very sedentary: 84 % of the recoveries were within 1 km of
the ringing site and 98 % within 10 km. The recoveries of the
20 birds that had moved more than 10 km did not indicate
any preferred dispersal direction. The longest distance for a
Danish house sparrow was 78 km. One bird was recovered
abroad (from Hesselø to Sweden), and one German and two
Swedish birds were recovered in Denmark. The main cause
of death is collisions with vehicles. Before 1970 11 % had
been reported killed in traffic and after 1970 the proportion
increased to 20 %. Before 1970 18 % had been shot and 4 %
killed by cats; after 1970 these proportions were 5 % and 8 %
respectively.
