Gaaf om te lezen, maar inderdaad, die internet redactie mag wel eens wat meer zijn best doen... toch wel opvallend hoe vaak er een foute foto bij nieuwsberichten over dieren staat. Ik zou zeggen check waarneming.nl eens!

Ja daar verbaasde ik me ook al over op Lesbos.
Tijdens de Birding Breaks reis maar door 2 mensen 1 vogel gezien, terwijl je normaal gesproken diverse ziet.
Ook anderen hebben weinig Grauwe Klauwieren gemeld, en op observado ook weinig!


Laten we idd er het beste ervan hopen want ik weet niet of Grauwe Klauw een soort is die snel een dergelijke klap teboven komt...

May 24 1700 EAT

Dear All,
Sending this with especial thanks to those birders whose emails are
incorporated below.
Various recent 'developments' may now be perceptibly affecting the
behaviour and populations of some passerine bird species during their
non-breeding season in Africa.
The following is simply what I have put-together from the various
emails I've received since Anders 'started the ball rolling' on
Saturday morning.
Please excuse cross-posting and updating of this thread - in real time!
I just want to make use of this relatively benign technology asap.
Hope we can encourage others to contribute their opinions/observations
more or less as they happen/don't happen.
Thanks a lot for your time,
James


Sweden:
This weekend [21/22 May] I have been chief administrator for the
biannual meeting of Club300.
All the birders I have met agree that something fishy is going one
concerning the Thrush Nightingales, as well as the Red-backed Shrikes.
The former have started to arrive these last two nights, the latter
are still lacking almost completely.
Anders Waldenström

********************************************************************************\
*****
Denmark:
Here in Denmark we are also wondering what have happened to Thrush
Nightingale and Red-backed Shrike.
Last week I looked at our internet-based database where we all report
our records (www.dofbasen.dk). On 14 May 2011 the number of entries
for Thrush Nightingale was 134 against 684 on the same date last year.
On 14 May 2011 the number of entries for Red-backed Shrike was 10
against 149 on the same date last year.
The picture is almost the same now (21 May).
Michael Køie Poulsen

********************************************************************************\
*
Belgium:
At the far north-western edge of the range in Belgium, similar
observations
concerning Red-backed Shrike are reported.
See this link, comparing the records for the species in the national
observation system:

http://waarnemingen.be/soort/stats/51?tab=

http://waarnemingen.be/soort/stats/51?tab=&id=&user=0&year=2011&month=0&sex=0
> &id=&user=0&year=2011&month=0&sex=0

In 2011, only 49 records (57 birds) for the species in May so far. In
2010,
there were 403 records (520 birds) in May (although this number does
concern
the whole month). Observers are reporting missing the species at it's
usual
haunts.
Wouter Fayets

*********************************************************************
Eastern France/Switzerland:
Here in France we've also been discussing likely causes of the
unusually late arrival of Red-backed Shrikes – in my area, they've
just started arriving in the last few days, which is about 2 to 3
weeks late.
A fairly logical explanation would be the weather conditions in the
Eastern Mediterranean this spring, which experienced frequent strong
northern winds, as well as higher than usual rainfall. Especially
during the first 2 weeks of May, Turkey/Crete was affected by this
weather. In contrast, Western Europe has had hardly any rain and
mostly southern winds. The preceding info was mostly translated from
data provided by F. Legendre and C. Calas (www.meteoc.fr).
This would explain why RBS arrived late, but not other species that
winter predominantly in West Africa such as Melodious Warbler.
Marsh Warbler seems to be arriving pretty much as usual – maybe
because a lot winter even further East, or because the spell of bad
weather is over now?
So for now I'm still hopeful that it's just a late arrival rather than
some unexpected population crash; my main worry though is that due to
their late arrival their young will fledge after the peak time for the
various medium-sized insects, and that mortality will thus be higher
than usual. This morning, I had about 5 pairs of RBS on a good site
near my home in Eastern France, which is similar to previous years.
Quite a relief to finally see them again!
Bram Piot

***********************************************************************
Hungary:
Interestingly, several birders and bird conservationists asked the same
question in the Hungarian and Transylvanian breeding range of Red-backed
Shrike because it has arrived at least two weeks later than usual from
wintering
areas and is apparently in low numbers.

R-bS is a common breeder in NE Hungary and it was strange to see none
until
mid-May.
András Kovács

************************************************************************
Bulgaria:
I saw my first red-backed shrike in north east Bulgaria on May 12th.
They are now here in very big numbers. One day there were none but
within three days everywhere you look you see one.
Through our facebook group, I am told the situation was similar in
other parts of Bulgaria. I am also told they arrived about 7 days
late this year. We have had the coldest April for a generation (in
complete contrast to western Europe) and anecdotally many migrants
passing up through eastern Europe are "behind schedule"

*****************************************************************************
Romania:
I collected a few reports on Red-backed Shrike in Romania. Accordingly
the species is late
by 2 to 3 weeks and started to build up just in the last few days. So,
in the
weekend most observers noted them as 'common' in S and SE Romania,
however I felt
that not all the breeding population has arrived yet in Central
Transylvania.
Attila Sandor

****************************************************************************
Lesvos:
We had a very weird holiday season in Lesvos this year with many
species being late (shrikes and warblers). NO Olive-tree by the time
we left, Rollers only just arriving and Bee-eaters the week we
arrived. Loads of Barred Warblers this year (we saw only one!). The
winter had been very wet, so everything was very green and the rivers
higher than last year, and so there we no reported Great Snipe.
Steve Chalmers

****************************************************************************
Cyprus:
There has been curiosity in Cyprus about the almost total lack of Red-
backed
Shrikes this spring. Normally passage commences in mid-April, with daily
records to mid-May. This year there were only 2 birds reported in April,
both on the 22nd, with virtually no more until around 17th May when we
experienced a trickle of birds for a few days. But passage has now
stopped,
with little sign of any more passing. Migration of other passerines
has also
finished in Cyprus.

The consensus is that it was a generally poor spring for
birders with much fewer migrants than usual.

I wonder what is going on?
Food availability, weather - problems in Africa?
Colin Richardson

*****************************************************************************
Israel:
in Israel this year there is a very big drop in numbers of birds
passing during Spring comparing to last years.
Nevertheless many of the species seems to have had a lag of 2-3 weeks
from their regular appearance dates.
Thrush Nightingales which are regularly seen from mid April and on
around Eilat, were arriving this year only around the second week of
May and last week they were one of the most abundant species after
Blackcaps.

I will be happy to hear more about the weather conditions you
described regarding the 'Greater Horn' as this may very well be one of
the key issues.
Itai Shanni

********************************************************************************\
*
UAE:
Red-backed Shrikes are very much an early-May bird in the UAE, rarely
appearing in any numbers in April.

In contrast, a trip to Ethiopia in April 2009 revealed an apparently
large passage of this species on 12-15 April (I don't have the exact
date in front of me).
Having only visited Ethiopia once, I cannot say whether this was early
or not, though I can say that there had been unusually heavy 'small
rains' and subsequent greening of the grasslands / Acacia woodland.

Tommy Pedersen (UAE recorder) and/or Oscar Campbell may have further
comment on this matter.
Nick Moran

*****************************************************************************
Somaliland:
We're seeing well-fed 'boat loads' of Thrush Nightingales as well as
the Common headed your way as I write this. There are excellent
numbers of these nightingales as well as migrant shrikes (Red-backed,
Lesser Grey, and Southern Grey) and even common starts on a move
your way, in a long front all the way to 45E.
Abdi A. Jama

******************************************************************************
Sahel etc.
First of all, I have no idea what the breeding season was like in
Sweden last year, nor do I know what may have happened to Swedish
passerines on their way between Sweden and Africa, or between Africa
and Sweden,

That being said, from James's and Abdi's responses one could
hypothesise that migratory passerines, like migratory waterbirds, may
show not only site fidelity but also opportunism: don't migrate
further south than you have to to survive and to fuel up for the
return trip. Sweden's Thrush Nightingales and Red-backed Shrikes may
be low in numbers this year, and/or late, as mentioned by Abdi,
because of drought conditions in northern East Africa during the past
six months, as described by James. The Great Snipe discussed
yesterday may be in Western Europe in greater number this year because
of high rainfall in the West African Sahel last year (June-Sep/Oct).
Perhaps Sweden's Whitethroats and Redstarts winter in West Africa
rather than East Africa, hence their high numbers this year.
Recoveries in Niger in West Africa, of birds ringed in Sweden, do
include 2 Sedge Warblers and 2 Willow Warblers, in addition to 5
Ospreys, 2 Wood Sandpiper and 2 Caspian Terns. When are the Swedes
coming to Niger to study and ring migratory passerines :-) ?

Related to poor conditions in the Sahel, the attached contribution by
David Kusserow and myself may be of interest. In brief, in September,
just at the end of the rainy season, when the passrines come down from
Europe, the Sahel is a green shore to the Sahara. In April, when they
move back north, at the end of the dry season, the Sahel is an
extension of the Sahara, EVERY year. In April, David, who lives in
Niger not far from Lake Chad, picks up Redstarts, White-throats etc.
that are heat struck before they even start to cross the Sahara. Some
pictures of heat struck birds have just been put on the blingual
(English and French) Niger Bird DataBase site,www.bromus.net/nibdab
(click on Photos and sort on order of entry).

*****************************************************************************
Uganda:
A few bits of information which are probably not much use to your
study, being the wrong side of the Rift Valley.
Had an entertaining few days in Kidepo Valley Nat Park 25-27 April
this year and saw good numbers of Shrikes, approx 120 Lesser Grey, 60+
Red-backed and 50+ Isabelline.
Also seen at least ten Red-backed and 8 Isabelline in Kampala last
autumn and this spring. These are far and away more than seen in my
previous year here in Uganda.
Whether a shift in migration patterns I cannot tell.
With reference to Marsh Warblers I have trapped 2 at Ggaba, Kampala
this winter which I think are the third or forth records of this
species in Uganda.
Have not seen Thrush Nightingale in Uganda but did see my first
Nightingale this spring.

********************************************************************************\

Tanzania:

1)
I attach our latest atlas map for Tanzania. This gives an accurate
feel for the wintering quarters here, there are very few knowledge
gaps in terms of range limits. Unfortunately we do not have sufficient
day dated records to compare year on year departures.
Our over-wintering garden bird at 7.731 South was last heard on 2nd
April. I'm asking our birding group for any other dates or significant
observations this past season. Rains, as ever, have been patchy in
both timing and distribution. Locally here they have been heavier that
"normal" but some farm dams within 20km are lower than they should be.
With only 166 ringing records and no recoveries I've no clue where our
birds breed but there is surely better data from the Ngulia ringing
group and many of these will be of birds that over-winter in Tanzania.
Neil Baker


2) Arusha:
On the Sprossers and Nightingales, I'm somewhat hesitant to comment
since I've hardly been home since November - just short periods.
However, it certainly seems as if we had very few Sprossers for a much
shorter time than normal. They are generally abundant and vociferous
here for the duration. While we do sometimes have nightingales around
they are never as numerous as sprossers. At the end of April/into May
(I was in S. A. much of April) all I saw was Nightingale but not many.
Interesting and I would guess as surmised on the blog that variable
weather patterns have a lot to do with this.
Cheers,
Daudi Peterson

3) JW
I suspect that the highly erratic, both spatially (they were
especially localised and capricious last season) and also in terms of
volume, vuli-rains which caused punishing droughts in many areas
across the 'Greater Horn' [i.e. from Red Sea coastline in NE Africa
down to southern Tanzania at least] during October- December may be at
least partly responsible for the late arrival of Thrush Nightingales.
Light-aircraft pilots here in Arusha remarked that the the ITCZ rolled
way south very quickly in November/December!

I felt that I was encountering fewer TNs than previously in northern
Tanzania during the late autumn passage/boreal winter.
In wetter years before they've been quite common through the Arusha
area, off-passage for many days, e.g. we get up to four daily in our
'garden' during late November-December; and in an El Niño 1-2 birds
probably 'winter'.

This past season I think they moved through much more quickly
southbound, and interestingly were soon replaced by the 'pale ones'
i.e. hafizi [Rufous] Nightingales, which in marked contrast, remained
in 'good numbers' until late in March. And of course L.l. likes to
forage and 'winter' in markedly damper situations than does L. (m.)
hafizi.
Also what about Marsh Warbler which, so far as I am aware, has been
very scarce this April-May in eastern Tanzania?

The first Red-backed Shrikes I saw this season were with a Sunbird
tour group at Speke Bay on 14 March. This is well to the west of the
Rift Valley and these birds were present in drought conditions, almost
unprecedented there. The Tanzanian shores of the Lake Victoria basin
e.g including the western corridor of the Serengeti NP and Speke Bay
were exceptionally dry up until March 20/21, when they received 65 mm
in one night at SB Lodge.

It seems likely it was not until mid-April that the first real wave of
shrikes came through the coastal strip at Tanga area (just south of
Kenya border) during plentiful rainfall there.
These long-heavy rains seem to have arrived, and be lingering, later
this season and so maybe many Palearctic migrants have likewise been
forced, fat-wise, to delay their departure.

In April I travelled on a rapid transect across the entire shrike
route (flight path).
Firstly from Arusha west to Lake Victoria back to Arusha and then from
Arusha to Ushongo, Pangani and back - Pangani is on the East African
coast just south of the Kenya/Tz border.
We went down to the coast on April 17 along the main NBI-Dar road
passing Mount Meru, Kilimanjaro, Same, Segera and Muheza (East
Usambaras).

There were no migrant shrikes visible on the way east to the coast
even though [unusually] we had seen many, our first ones, at Ndutu
(>30) way out in the steppes at the western Ngorongoro CAA/Serengeti
NP boundary on April 15/16. The complete absence of RBS along the main
highway on April 17 was a remarkable and disturbing fact, as 'usually'
there are scores and scores along this roadside by mid-April.

Early in the next week, at the Indian Ocean coastline, we had three
significant rain storms, especially on 18/19, during which there were
falls of both shrikes and also Spotted Flycatchers
We returned west on the same route during April 18/19/20 via a stop-
over near Nyumba ya Mungu reservoir o/n on 19th.
On the slower return trip westwards, inland through good shrike
habitat (April 25-28), we saw a small number of female Red-backed
Shrikes but, by now, very few males.

Red-backed Shrikes, especially males who presumably usually come
through first, appeared to be in lower numbers and definitely peaked
over a week late.
They were much very concentrated in those areas where there had been
recent heavy yet isolated showers, these were chiefly west and east of
their normal flyway. Especially, and perhaps somewhat unusually, west
of the Rift at Ndutu, and east right along the coast south of Pangani.
There were very few birds in much of the central 200km wide part of
their 'normal flyway route' on April 17.
This northbound route is through the savannas of eastern Tz between
Kilimanjaro and the coastal strip i.e. just south of Amboseli and the
two Tsavo parks in Kenya.

********************************************************************************\
**
RSA:
At Nylsvley Nature Reserve in northern South Africa, Red-backed Shrike
is a common summer visitor to this semi-arid savanna.
Annual bird counts are done across the 4000 ha reserve each year
(2000-2011 so far) in the last week of January (18 standard transects
in acacia and broad-leafed woodland, each team walking from 06h00 for
2 hours counting all birds encountered). The shrike is usually one of
the top 20 species counted, but numbers fluctuate massively from
season to season (between 15-76 birds/a); in the last 4 years numbers
counted have been below-average. For the 12 years of data, the Red-
backed Shrike numbers counted were, in chronological order: 42, 53,
17, 61, 76, 33, 26, 35, 30, 21, 15, 31.

Because it is a conspicuous bird these ups and down are probably a
real reflection of the relative commonness of the bird over the years.

De onderzoekers van het NIOO/KNAW hebben weer wat onderzocht (want ja, daar zijn ze voor), de ganzen zitten de laatste tijd al in het verdomhoekje, dus laten we ze ook maar de schuld geven van de opwarming van de aarde. Met zinnen als "de overgebleven rietstengels fungeren als schoorstenen", klinkt het natuurlijk wel erg stoer, maar ik zou de zaak nog eens goed onderzoeken. Het gas wordt geproduceerd door onze grote vrienden, de bacterieen en o.a. opgenomen worden door de wortels van planten, en volgens het verhaal van het NIOO kunnen er meer gassen vrijgelaten worden door de kort gevreten stengels. Maar dan moet er toch ook meer geproduceerd worden (misschien zaten er per vierkante cm wel 5 keer zo veel bacterieen)? Er kwam zelfs 5x zo veel methaan vrij!! Ben benieuwd of ze andere mogelijke factoren uitgesloten hebben?

Ze benadrukken gelukkig wel, dat het een natuurlijk proces is en dat we de ganzen daarom niet moeten gaan afschieten (gelukkig maar, want dat gebeurd toch al).

Maar goed, hier het artikel: http://vwgdepeel.ivnastensomeren.nl/nieuws/nieuwbroeikasgaslekontdektinwetlands01062011.htm
