Eggs laid in the UK by the world’s largest flying bird mark huge conservation success

24.07.2007
The scientist involved in helping re-introduce the Great Bustard to the UK is “delighted” that birds released at a secret Wiltshire location have laid their first eggs.

Dr Tamas Szekely from the University of Bath says that the announcement from the Great Bustard Group comes a year earlier than predicted, and shows that the project is making good progress.

The Great Bustard is the world’s largest flying bird and although it was hunted as a trophy until it became extinct in the UK in the 1830s, it still lives in stable populations in eastern Europe.

Since 2004, the Great Bustard Group has released more than 60 Great Bustard chicks, all hatched from eggs salvaged from nests destroyed by cultivation.

Due to fears of egg thieves and disturbance from bird watchers, the announcement that eggs had been laid in the UK was delayed. The eggs were incubated for a time by the female but were then abandoned. After examination they were found to be infertile.

“Males need to be four to five years old before they can breed, so the fact that the eggs were infertile was not a big surprise,” said Dr Szekely who is the project’s scientific adviser.

“What is encouraging is that the eggs were laid in the first place; unhappy birds do not produce eggs.

“The males have a spectacular courtship display which was seen in this country for the first time in over 175 years this year.

“This is a very exciting time for the project, and marks an important step towards a breeding population of Great Bustards in the UK.”

Male Great Bustards stand around 90-105 cm (about 3 ft) tall and can weigh up to 20 kilos (3 stones). Females tend to be much smaller.

“Great Bustards are a magnificent species and birdwatchers have it as one of their top species to see,” said Dr Szekely, from the University’s Department of Biology & Biochemistry.

“They are shy and easily disturbed, so it is encouraging to see these developments.

"They next step is to see the first Great Bustard chicks hatch, and we very much hope that will happen within the next two years.”

Im Focus: Giant Magnetic Fields in the Universe

Astronomers from Bonn and Tautenburg in Thuringia (Germany) used the 100-m radio telescope at Effelsberg to observe several galaxy clusters. At the edges of these large accumulations of dark matter, stellar systems (galaxies), hot gas, and charged particles, they found magnetic fields that are exceptionally ordered over distances of many million light years. This makes them the most extended magnetic fields in the universe known so far.

The results will be published on March 22 in the journal „Astronomy & Astrophysics“.

Galaxy clusters are the largest gravitationally bound structures in the universe. With a typical extent of about 10 million light years, i.e. 100 times the...

Im Focus: Tracing down linear ubiquitination

Researchers at the Goethe University Frankfurt, together with partners from the University of Tübingen in Germany and Queen Mary University as well as Francis Crick Institute from London (UK) have developed a novel technology to decipher the secret ubiquitin code.

Ubiquitin is a small protein that can be linked to other cellular proteins, thereby controlling and modulating their functions. The attachment occurs in many...

Im Focus: Polymer-coated silicon nanosheets as alternative to graphene: A perfect team for nanoelectronics

Silicon nanosheets are thin, two-dimensional layers with exceptional optoelectronic properties very similar to those of graphene. Albeit, the nanosheets are less stable. Now researchers at the Technical University of Munich (TUM) have, for the first time ever, produced a composite material combining silicon nanosheets and a polymer that is both UV-resistant and easy to process. This brings the scientists a significant step closer to industrial applications like flexible displays and photosensors.

Im Focus: Researchers Imitate Molecular Crowding in Cells

Enzymes behave differently in a test tube compared with the molecular scrum of a living cell. Chemists from the University of Basel have now been able to simulate these confined natural conditions in artificial vesicles for the first time. As reported in the academic journal Small, the results are offering better insight into the development of nanoreactors and artificial organelles.
