The European
Roller, Coracias garrulus, is the only member of the roller family of
birds to breed in Europe. Its overall range
extends into the
Middle East and Central Asia and Morocco.
The European
Roller is a long-distance migrant, wintering in southern Africa in two
distinct regions, from Senegal east to
Cameroon and
from Ethiopia west to Congo and south to South Africa.
It is a bird of
warm, dry, open country with scattered trees, preferring lowland open
countryside with patches of oak Quercus
forest, mature
pine Pinus woodland with heathery clearings, orchards, mixed farmland,
river valleys, and plains with scattered
thorny or leafy
trees.
It winters
primarily in dry wooded savanna and bushy plains, where it typically
nests in tree holes.
The European
Roller is a stocky bird, the size of a Jackdaw at 29-32 cm in length
with a 52-58 cm wingspan, but it is mainly
blue with a warm
brown back.
Rollers often
perch prominently on trees, posts or overhead wires, like giant shrikes,
whilst watching for the large insects, lizards and frogs that they eat.
This species is
even more striking in its strong direct flight, with the brilliant blue
contrasting with black flight feathers. Sexes are similar, but the
juvenile is a drabber version of the adult.
The display of
this bird is a lapwing-like display, with the twists and turns that give
this species its English name. It nests in an unlined tree or cliff
hole, and lays up to six eggs.
The call is a
harsh crow-like sound. It gives a raucous series of calls when nervous.
The European
Roller has a large global population, including an estimated
100,000-220,000 individuals in Europe. However, following a moderate
decline during 1970-1990, the species has continued to decline
especially in Europe, with overall European exceeding 30% in three
generations (15 years). In Estonia
the 50-100 pairs
in 1998 have reduced to no known breeding pairs in 2004; in Latvia and
Lithuania populations have decreased from several thousand of pairs in
the 1970s to under 30 pairs in 2004. In Russia it has disappeared from
the northern part of its range. However, there is no evidence of any
declines in
Central Asia.
The decline in
the European population has resulted in its Red List status being
upgraded from Least Concern to Near Threatened in 2005. Threats include
persecution on migration in some Mediterranean countries and hundreds,
perhaps thousands, are shot for food in Oman every spring. Use of
pesticides
reduces food
availability, and the species is sensitive to changing farming and
forestry practices.
