Common
Buzzard of Britain and Ireland
The
Buzzard (Buteo buteo) has recently become the commonest and most
widespread bird of prey in Britain. Their population has rapidly
increased over the last twenty years, particularly in England.
Buzzards became extinct in Ireland until a breeding pair was reported
in 1933. The population of Irish Buzzards has also increased and are
now found in most counties in Ireland.
Other
names for the buzzard are the Common Buzzard and Eurasian Buzzard.
Buzzards
are medium-sized birds of prey with wingspans reaching up to between
113 and 128 centimetres, or between 3.7 and 4.2 feet. Males and
females are alike although females have larger talons and beaks.
Adults
start breeding when they are three years old. The average lifespan of
the Buzzard is 12 years.
Pairs
of Buzzards live and breed on their territories in a wide variety of
habitats throughout the year. They are normally found in woodland,
moors, heaths, farmland, bogs, marshes.
Villages
are some of their typical haunts although they are now regularly seen
near large cities such as Glasgow.
Pairs
remain on their territories throughout the year and seldom move more
than 100 kilometres or 62 miles, Hunting often takes place outside
their territory along the edges of forests or on open land.
The
main prey of the Buzzard are voles, mice, rats, moles, rabbits
and hares. They are generalists who also eat young birds such as
pigeons and crows, earthworms, amphibians, large insects and carrion
such as roadkill.
A
great deal of their time is spent perched on trees or poles so they
can swoop down on their prey. Buzzards make a cat-like “peee-uu”
sound which can be heard during the year.
Buzzards
have been resident in every county in Britain since the 1990s. The
strongholds of the Buzzard are Scotland, Wales, the Lake District and
south-west England. Their range has extended from Lincolnshire, East
Anglia and down to Kent since 1991.
The
population of Buzzards has increased significantly in Northern
Ireland since 1995 according to the British Trust for Ornithology.
The
Raptor Study Group in Ireland said “For a bird which became extinct
in 1891 in Ireland and only began breeding again on Rathlin in 1933,
its current breeding status is remarkable.
Buzzards
were “believed to be currently breeding in 18 counties across
Ireland with the expectation that it will eventually re-colonise
every county in the future

Pairs
form lifelong bonds and begin breeding between April and May. They
normally re-use an old nest in a tree on the edge of woods, a cliff
or rocky crag.
Both
the male and female make an untidy nest of branches and lined with
soft material such as twigs, heather and bracken.
Two
to three eggs are laid in April which hatch after 34 days. The chicks
learn to fly after 44 to 52 days. The young are cared for by the
parents for another 40 days when they become independent.
Sadly,
most young buzzards die of starvation before reaching adulthood.
The
Common Buzzard is classified as of Least Concern by IUCN.
Europe
holds approximately 75% of the global population. Their numbers in
Europe are stable according to Birdlife International.
The
Buzzard is a green-listed species of bird in Britain.
Buzzards
were common birds of prey across Britain until the nineteenth
century. However, persecution by gamekeepers reduced the population
to 1000 birds by the 1900s. They were only found in the western areas
of Britain by the beginning of the twentieth century.
The
number of Buzzard rose during the First and Second World Wars as
killing birds of prey was made illegal.
The
population of Buzzards was thought to be 10,000 by the mid-1960s.
The
use of organochlorine pesticides caused a fall in the number of
Buzzards between the 1950s and 1960s. Their food supply was also
reduced during this time as myxomatosis killed over 90% of Britain's
rabbit population.
The
number of Buzzards increased rapidly during the 1990s with an
estimated 68,000 pairs in Britain by 2013. Their numbers increased
because of less persecution and banning of harmful pesticides.
The
population increased rapidly in England by 2009 according to the
British Trust for Ornithology. There was a range expansion in central
and eastern Britain, making the Buzzard “the most abundant diurnal
raptor in Britain”.
The
charity also stated there was a “widespread rapid increase across
Europe since 1980” (BTO
- https://www.bto.org/birdtrends2010/wcrbuzza.shtml ).
Some
of the main threats to Buzzards are human interference when nesting
and ongoing persecution from gamekeepers.
Bird
charities were concerned when Natural England issued a licence to a
gamekeeper to kill 10 Buzzards. The gamekeeper believed Buzzards
threatened his pheasant farm. They objected to issuing more licences
by Natural England.
“Raptor
persecution... is difficult to police, difficult to prove and even
more difficult to punish” (Wildlife Articles
