Welcome Back, The Hobby

In the bird world, now is the time of year when we
start welcoming summer visitors back to these shores.
Garden birds like Swifts, House Martins and Swallows
have already put in an appearance, and they have been
closely by the Hobby, a small bird of prey which,
year upon year, follows the migration of all these
species as they work their way back to the UK from
Africa.
Migration is the process by which species of animals
move from one area to another for the reason of
reproduction. Longer days and warmer weather give
birds a better chance of success rate when raising
young and so the migration pattern is from the south
to the north in our summer, and the reverse in
winter.
Hence Hobbies usually arrive late April and leave
again just before the start of September. This year,
one individual was recorded locally to SOS, near
Needham Market in Suffolk, as early as April 13th.
They are not an overly-common visitor to these
shores, but in recent years numbers have been on an
increase, particularly in the south of England.
The Hobby is only a very small falcon of a size
similar to our native Kestrel, though it has a
shorter tail and distinct, 'sickle’-shaped wings
which enable it to do fantastic aerobatic stunts as
its chases its prey. The favoured diet of Hobbies is
large flying insects such as dragonflies and the
bigger moths, which they will eat while still on the
wing - they can often be seen chasing moths just
before dark. Hobbies are also the only raptor capable
of chasing and catching the speedy Swift in flight.
In order to catch prey, Hobbies will usually cruise
out of sight at high altitude, waiting for the right
moment to close their wings and plummet to earth at
speeds which can be in excess of 100mph, only opening
their wings again when they are just a few feet of
the ground.

Hobbies inhabit areas like heathland, near to the
edge of woodlands, and around farmland. If you have a
disused crow or rook nest locally, look out there too
as Hobbies favour their abandoned nests - though as a
result, a few chicks can be lost to these corvids
before they get the chance to make the journey back
to Africa.
As a rule the female Hobby will lay 3 eggs, which
hatch in about 4 weeks: the chicks will take 4-5
weeks to fully fledge and then another 4-6 weeks to
become completely independent. Young Hobbies learn to
catch prey by first catching slow-flying beetles,
then progressing to the faster species as they become
more practised at the art.
The name “Hobby” is said to come from the Old Dutch
“Hobben” - which means to move up and down or side to
side quickly - which describes the way the bird flies
to catch its prey.
The Latin name for the Hobby is Falco Subbuteo - you
may recognise this name from the tabletop football
game. This is because the inventor of Subbuteo was a
Peter Adolph, who in his spare time was a keen bird
watcher and the Hobby was his favourite bird. When
applying for the patent, he wanted to register the
game as ‘The Hobby’: this was turned down but the
name of ‘ Subbuteo’ proved quite acceptable to the
powers that be and which explains why the game
carries crests and emblems which feature the head of
the falcon on most versions produced
today.
