Linnet and geese on Goeree island

Wednesday, 29 July.

To Goeree-Overflakkee island.

Linnet maleAt the ferry in Maassluis, black-headed gull and common tern.

On Voorne island, a goat drives away a grey heron. From a reed-bed, reed warbler sound.

Crossing the bridge to Goeree, common terns.

Then, the hide at Kwade Hoek nature reserve.

A marsh harrier flying. A kestrel sitting on a pole.

Many grey lag geese; three Canada geese; two barnacle geese.

A male linnet sitting on a leafless branch.

On the beach of Ouddorp: herring gulls, black -headed gulls, oystercatchers.

It is low tide now, which means many shallow pools on the sandy beach. Common terns skydive in those pools. Which means they must be good at putting on the brakes, or they might hit the bottom in those shallow pools. At least twice, a tern flies away with a small fish.

A swift. Probably one of the last of this summer.

East of Ouddorp, in the dunes, a rabbit and a male pheasant.

New bird species discovered in Laos

Bare-faced bulbul

From BirdLife:

New ‘bald’ bird discovered

30-07-2009

An odd songbird with a bald head living in a rugged region in Laos has been discovered by scientists from the Wildlife Conservation Society (WCS) and the University of Melbourne …

The species has been named Bare-faced Bulbul Pycnonotus hualon because of the lack of feathers on its face and part of its head, it is the only example of a bald songbird in mainland Asia. It is the first new species of bulbul – a family of about 130 species – described in Asia in over 100 years. A description of the new species has been published in the July issue of Forktail, the journal of the Oriental Bird Club.

Biggest leopard research project ever

From PRWeb:

Conserving Big Cats Works: Proof Published from South African Leopard Field Study

The Munyawana Leopard Research Project at Phinda Private Game Reserve in KwaZulu-Natal began in April 2002 and has been instrumental in the long-term conservation of local leopard populations.

Guided by Dr. Luke Hunter and Guy Balme from Panthera, the research is the most comprehensive study on leopards ever conducted, specifically in terms of the length of study, the number of leopards collared and the outputs generated from the research. Since inception, 64 leopards have been collared (the highest recorded in previous studies was 31), over 13000 locations logged and more than 1600 direct leopard observations made.

Fossil rodent discovered in Spain

Fossil and living rodents

From FECYT – Spanish Foundation for Science and Technology:

Extinct rodent species discovered

An international team of scientists has discovered an extinct rodent species, based on fossil tooth remains found in Alborache, Valencia. Eomyops noeliae, from the Eomyidae family, represents the oldest find within this genus in the world.

The small number of fossils found has prevented the scientists from the University of Valencia (UV), who have led this research study, from being able to gain a full picture of this “new” rodent. However, they have been able to prove – on the basis of just the teeth, the only fossil remains discovered – that Eomyops noeliae was morphologically and biometrically different from other rodents of the Eomyops genus. The new species provides valuable evolutionary, biostratigraphic and paleoenvironmental information related to this rodent, which was of average size within the group.

“Until now, the Eomyops genus was made up of a group of small species and one large one, but no intermediately-sized kinds such as Eomyops noeliae had been found”, Francisco Javier Ruiz-Sánchez, lead author of the study published in the French journal Comptes Rendus Palevol and a researcher in the UV’s Department of Geology, tells SINC.

The palaeontologists have also confirmed the age of the find. “The fossils found in the Morteral 20A deposit in Valencia show that this is the oldest species within the genus known in the world with absolute certainty”, points out Ruiz-Sánchez. According to this data, Eomyops noeliae would have lived during the Aragonese period “perhaps between the Lower and Middle Miocene (around 16 million years ago)”, underscores the researcher.

The rodent’s wet environment

The varied fauna of micro-mammals and the new species found in the Valencian deposit provide information about the environmental conditions in which these animals would have lived at the time. “The rodent taxa found show evidence that the environment was very wet”, says Ruiz-Sánchez, even though the full study on all the fossil rodent remains, begun with this new eomyid, has still not been completed.

According to the study, the environment was “relatively thickly wooded, and the climate was wet”, although other factors such as temperature have not yet been defined.

The biogeographical data also show that Eomyops noeliae lived throughout the east of the Iberian Peninsula during the Lower-Middle Miocene. This has been confirmed from the Eomyops species remains excavated from the “most recent” Morteral 22 deposit, which is very close to Morteral 20A.

Ruiz-Sánchez says the finds of this species’ teeth in deposit strata separated by just a few metres show that “how this species survived in the east of the peninsula over a specific time period that is currently hard to define, but which must have gone on for several tens of thousands of years”.

Baillon’s crake again

Like yesterday, to the Baillon’s crake nest area.

I saw the male and the female. Others had seen the three chicks.

Like yesterday: redshank, shelduck, great cormorants, lapwing, black-tailed godwit.

Unlike yesterday, a water rail.

This video from England says about itself:

Later, in the meadow near the nature reserve, all four white storks are present.

Scottish mountain dragonfly record

From the BBC:

Dragonfly discovery a ‘UK record’

A dragonfly found laying eggs in a mountain pond has set a UK record for the species, Highland Council’s biodiversity officer has said.

Jonathan Willet said the female common hawker was at 830m on Tom a’Choinich, north of Loch Affric – the greatest height it has been found in the UK.

The previous highest recorded breeding was at 650m.

Mr Willet said the species – one of 18 dragonfly and damselfly found in the Highlands – favoured warm temperatures.

He said: “This species does breed very high up in continental Europe, up to 2,700 metres in the Swiss Alps, but the summers are a lot warmer there.

“The pond is found in a sheltered location in a south facing corrie, so this must create a warm microclimate within the pond allowing the larva to develop, but it may spend five years as a larva before it is fully grown and ready to emerge as an adult, which may only live for three to four weeks.”

In May, Cairngorms National Park Authority asked the public for help surveying old curling ponds, lochs and bogs to gauge the numbers and varieties of dragonfly and damselfly in the park.

The area is believed to provide habitat for 13 types of the large insects.

A tiny creature no bigger than 1mm in length found in the Scottish hills has been confirmed as the first recorded member of its species found in the UK. The springtail Bourletiella viridescens was photographed in the Cairngorms by Tim Ransom: here.
