Pigeons and holly
An interesting sight on a freezing cold Friday morning - EIGHT wood pigeons
in the same holly tree stripping berries. There did not seem to be any
territorial aggro. so I wonder if they were related - this tree is a highly
favoured nest site for pigeons and other birds.

I noticed that the crop of blackberries this year was very poor, with
perhaps less than a tenth of a normal crop, showing nearest to the
ground, and the rest just brown husks.
At the same time, in my local area too, acorns only showed on some
saplings. That's only 2 years after it happened before.
I am not sure if holly berries are normal fare for pigeons. (Wood pigeons?)
There have been none on my tree.(It's under an oak tree)
Blackbirds have started early on my pyracantha berries(red). Some years
they leave them alone. All the Mountain Ash berries were stripped as usual.

Pigeons are gregarious during the winter and don't go in for territorial
aggro.

I've seen 10s of blackbirds in a blackthorn hedge just down the way
gorging themselves, as well as all out Pyracanthus berries went last
week. As you say I've seen the berries left on the bushes before... a
portent of bad weather to come ?

Not really sure I'd say it is a portent of a bad winter but the
countryside is *full* of fruit around here (Thames Valley - rose-hips,
privet, hawthorne, sloe, spindle, crab apples etc) and the weather is
fairly mild, compared with eastern Europe, so I just think the birds
are here and making the most of the crop.

There has been very heavy and early snowfall in parts of Scandinavia
this autumn (1) which has sent a lot of birds here earlier and in larger
numbers than usual, including thrushes, siskins, bramblings, etc.
(1) Must be global warming :-)

Hi Malcolm,
Would it depend on whether these Pigeons are ours or continental birds and
if so what would they be happy eating themselves silly on.
I for one, have seen a huge flock of many many thousands a few years back
gorging on left over maize and all were birds were largely gone within
hours.

Ours do! Intruding pigeons cause the most frightful flap if they come near
this holly tree once nest building has been started by the first comers.

How many pigeons actually come across from the continent is a matter of
some dispute, believe it or not. A recent analysis of ringing recoveries
showed minimal movement of continental birds into Britain except in very
hard winters. They will eat whatever is going in the vegetable line,
whether seeds, brassicas, growing plants of various kinds, etc.

They had presumably exhausted the food supply and had moved on.

I certainly do believe this is a matter of dispute, I think there certainly
should be a need to ring a few of these woodies in the name of scientific
research, methinks. I would not dispute it when many birders are currently
involved in personal studies along the south coast either!

Interesting, they certainly like to stock up, what with these super large
pigeons that have been witnessed.

Indeed, they were not seen again that year in those sort of numbers and must
have headed somewhere far afield in what I would call a monster flock, I
couldn't even enter the actual figure on Birdtrack at the time either!
Thanks Malcolm. Very informative and talking of which try the following
websites on vis mig and just look at the numbers of the wood pigs in
October/November this year.

The latest ringing totals to hand (up to 2005) are just over 42,000
ringed and c.3000 recoveries.
It is quite usual to see large numbers of woodpigeons flying along our
coasts in autumn, e.g. south down the coasts of East Anglia and west
along the Channel coast. These are considered to be continental birds on
migration.
Here are a couple of extracts from The Migration Atlas (2002).
"During October, Scandinavian and Baltic [breeding] birds move through
Denmark, the Netherlands and France, some continuing southwest through
the western end of the Pyrenees where they have been trapped in large
numbers for food. For many, their goal is the acorn harvest in the
forests of northwest Spain."
"There has been much debate concerning the arrival of foreign
Woodpigeons in Britain, and the emigration of British birds to the
Continent. The evidence has largely been based upon direct sightings of
birds either coming in from the sea onto the east coast of England, or
leaving the south coast of England and departing southwards over the
English Channel. Murton and Ridpath (1962) argued that most of these
observations resulted from Woodpigeons 'coasting and occasionally making
sallies for short distances out to sea and then returning'. They
concluded that only a small number of British Woodpigeons actually
emigrate to the Continent and, similarly, that very few foreign birds
reach these shores during their autumn migration.
More systematic watching of the coast in recent decades has revealed
annual movements in late autumn, westward along the North Norfolk coast,
but southward along the coasts of Yorkshire and Suffolk. The numbers
involved vary greatly from year to year. In 1994, an exceptional total
of 88,397 birds was logged flying south at Landguard Point in Suffolk
between 10 October and 25 November, with 30,610 birds on 2 November
alone. It is likely that the majority of these birds are from
Fennoscandia and heading for France or Iberia, and are not in Britain
long enough either to be ringed or for any rings they are carrying to be
recovered. If on the other hand they are British, then the ringing
recoveries are greatly underestimating the scale of movement of
British-bred birds.
Certainly the ring-recovery data contain no evidence of widespread
immigration into Britain; indeed, despite many long-distance recoveries
on the Continent, just eight foreign birds, ringed in the Netherlands
(three), Germany (two), Denmark, Norway and Belgium, have been recovered
here."

That's interesting, Malcolm but I do wonder where my local feeding flock of
c50,000 had originated from? if they were all local birds, there must have
certainly been some big roosting flocks about too.
