has taken me all around the North Sea, the Mediterranean, the
Baltic and the waters off NW Australia.
Usually there has been little opportunity to birdwatch but occasionally
there has been time on deck......

come from all kinds of survey and construction
vessels I have worked on. Most work has been related to the
and gas industry but there have also a number of other projects
hunting and salvage. The amount of time spent on deck has varied
enormously but the norm has been very little - it is far from one long
pelalgic birding trip! Many of the chance sightings I've had make me
wonder just how much gets missed.
surprising number of "land birds" seen offshore on oil
platforms and vessels; often more passerine species than
noted during a trip to work - at least during the
migration seasons. Any haze, cloud or rain can
bring "falls" of migrants onto the decks, waders do not land often but
will regularly circle a vessel at night before moving on at daylight.
Osprey was photographed as it rested on the aft mast some 10 km NW
of Ibiza in the Mediterranean in April 2005. The picture was taken
using binoculars as a telephoto lens - no easy task as I had to hold
onto the forward mast with my thighs whilst reaching around the mast
with binoculars in one hand and digital camera in the other - with the
vessel constantly rolling this was something of a challenge!
flares often cause birds to become disorientated and can at times cause
a lot of mortality
offshore presents some problems, one of which is that any land
birds are seen totally out of context and habitat, often making
identification surprisingly difficult. However, it also provides some
interesting insights into migration and the adaptability of many
species of bird.

Lange, June 2009
For more details about this and other highly unusual feeding behaviour
birds finding food
"bird table" consisting of some biscuit crumbs flung
onto the roof of a 20' container on deck once attracted two unlikely
species feeding side by side - a Little Stint alongside a Lesser
Whitethroat! On other days during the same trip more likely visitors to
this food supply included Song Thrush, Chaffinch and Brambling. One
surveyor turned birder famously "planted" a tree on deck on which he
hung fruit and other food for exhausted migrants - even after the
leaves had fallen off the bare branches continued to attract all kinds
typical perhaps that flocks of Common Starling or Jackdaws raid
the rubbish skips for food - although this behaviour is perhaps limited
to rigs as ships do not tend to have open skips on deck. These birds
turn provide food for owls and raptors. I have experienced a Long-eared
Owl swooping low over the deck to snatch a Starling in each talon
before flying back up to its roost site in the crane to devour its
prey. Other such sightings have included Kestrels hovering in the
updraughts around the bridge pouncing on exhausted Robins sheltering on
the deck below, or Sparrowhawks weaving in between containers, winches
and other gear on the deck to catch unwary Bramblings.....
of birds are regularly accompanied by movements of insects,
or perhaps it is the other way around. Frequently birds that land
onboard manage to catch these insects - often prey items larger than
they would normally take. Moths such as the Silver-Y moth are regular
in the North Sea during the summer and autumn and can provide
a source of noursihment for tired migrants.
insects such as this Silver-Y moth may help birds survive as
they cross the inhospitable waters of the North Sea.
many birds that land on offshore installations and vessels
die. Already in a weakened condition when they come onboard they
succumb to starvation, dehydration and exposure. This male Common
Redstart is just
such an example:
up inside cabins...
Some birds find their way inside the vessel and I have entered my cabin
to find a Northern Wheatear sitting on my bunk or a Barn Swallow flying
around in panic. The most remarkable incident was perhaps a
Yellow-browed Warbler which suddenly turned up on top of my computer
monitor one night - I caught it easily in my hands and slipped it
Other odd experiences have been wandering out onto the deck at night
only to have a Dunlin run over the deck towards me, stand next to my
boot and look me up and down before scuttling off a few metres in a
surprising display of tameness. A Bluethroat onced perched on my foot
on the back deck of a vessel off SW
Portugal and there have been countless other episodes concerning more
run of the mill
Passerines alighting on
Somewhat surprisingly I have seen species such as Woodpigeon and
Fieldfare actually land on the sea before taking off again on several
occasions. One would have thought they were doomed to a watery death
should they land at sea.....However, passerines landing on the sea is
no new phenomenon - in 1899 off the coast off Northern Virginia a
Chuck-will's-widow (a North American Nightjar-like species) was
observed landing repeatedly on the sea - and watched scoffing
warblers. Read more about this fascinating account here
in the Auk archives.
In volume 48 of British birds (1955) there is also a mention of a
Skylark and some Starlings landing on the sea, only to take off again,
apparently none the worse for wear. In contrast to my own experiences
this article states that the birds were not actually seen to land
deliberately on the sea.
Not just birds.....
