Fledging ravens and northern bald ibis chicks

A couple of months ago there were just eggs in the nests of the northern bald ibises and the ravens. Now their chicks can fly. Before they fledged, all of them were marked with coloured rings or wing tags and measured. The goslings will fly soon too.

Visitors at the KLF

During the past few weeks we were happy to welcome important visitors at the KLF:

Field work

The KLF is an excellent place for biological field work. Students of the University of Vienna accomplished here a part of a lecture about methods of field working and collaborators of the Max Planck Institute for Evolutionary Biology in Plön (Germany) visited us in order to catch blackcaps and equipped them with geo-locators.

What is Citizen Science?

Scientists from different Vienna Universities give their answers to this question and their opinion about challenges, additional benefits and future of citizen science in Austria. Here is the link to the videos promoted by the Knowledge Transfer Center. The videos are in German.

WANTED: Internship candidate

We are searching for a volunteer, who might be interested in assisting with field work for the duration of three months beginning with June. Please contact Josef Hemetsberger for any further matter. Opens window for sending email

Offspring at the KLF

The northern bald ibis chick from Othello and Aleppo was our very first hatchling; some days later the first raven chick from Paul and Luise hatched, and since last week als the first goslings are on their way.

Citizen Science Project

From April to June a Citizen Science Project is running with our greylag geese in the Cumberland game park. The visitors will have the possibility to observe the spatial and daily patterns of the greylag goose families. Also 8 school classes from Grünau and Scharnstein are joining this project.

New paper out

Our new paper Effects of mate separation in female and social isolation in male free-living Greylag geese on behavioural and physiological measures is online. Here is the link to the paper.

Congratulations to Georgine Szipl!

Georgine successfully defended her PhD in Vienna. Her research was about social relationships and acoustic communication in free-ranging common ravens.

More information can be found here.

Her publications:

With whom to dine? Ravens' responses to food-associated calls depend on individual characteristics of the caller

Craving ravens: individual 'haa' call rates at feeding sites as cues to personality and levels of fission-fusion dynamics?

New paper out: Fission-fusion dynamics over large distances in raven non-breeders

The group dynamic of non-breeding ravens was analysed in the frame of an international scientific cooperation. More than 300 marked ravens were regularly observed at specific foraging places in Austria and Italy and some of them were additionally monitored with GPS. Results show that some of the ravens tend to stay in the same place, whereas some others move around over thousands of kilometres. However, they often meet each other and keep in contact with each other. Therefore the result is a highly dynamic system.

Breeding season has startet!

At the moment it is silent at the KLF, because only some birds are here. This is because most of the greylag geese and northern bald ibises are building their nest or already breeding. The first chicks will hatch in April.

New students

We welcome our new students!

Lara Laiza form the University of Udine (Italy) is working with greylag geese, Teresa Schaer and Mario Gallego Abenza started their research project with ravens. Lovre Culina from the University of Zagreb (Croatia) is as an Erasmus student working with captive ravens at the KLF and at Haidlhof.

Knowledge transfer

Even on cold winter days it is possible to successfully work on knowledge transfer with interested children! At the end of January a small group of gifted children (Verein Talente OÖ) were involved in getting to know the animals and the work of the KLF. Additionally, they also spend a whole day here collecting and analysing their own data as real biologists and interviewing experienced researchers like Prof. Kotrschal and Prof. Bugnyar.

On February, 3rd a "Waldrappaktionstag" was promoted by our partner the Nationalpark Kalkalpen in the primary school in Ternberg. Approximately 60 pupils aged between 8 and 10 participated to different and funny activities about the Northern Bald Ibis and the work of the KLF.

Visit from the Wolf Science Center

We were happy to welcome many colleagues of the Wolf Science Center visiting the Almtal and the KLF.

New Paper online

Social (paired/unpaired) an environmental (temperature, season) factors modulate leucocyte profiles in free-living Greylag geese. The results and the whole paper can be found here.

New building for the KLF

The research centre gets a new home. It will be built next to the Cumberland game park. Start of work will be in spring 2017, completion of the builing in 2018.

 AniMove course

Our colleague Verena Pühringer Sturmayr participated in an AniMove course in Frankfurt am Main (Germany). There she leart basic techniques how to analyse animal relocation data.

Symposium on the PH Tirol about Visible Didactis

In cooperation with the PH upper Austria we organised a workshop at the symposium on the PH Tirol. The topic of the workshop was the benefits for the pupils from our sparkling science projekct

The pupils from Mühldorf are the Sparkling Science-Slam-Champions 2016

The children of the primary school in Mühldorf (OÖ) were successfully participating in the Sparkling Science Slam by presenting their project Social cohesion and flying behaviour in Northern bald ibis. With their entertaining and understandable presentation they convinced jury and audience and won the finale in Vienna. Congratulations!

NBI- action day in the primary school of Molln

On November 18th 2016 a Northern bald ibis action day was hold in the primary school in Molln in cooperation with the National Park Kalkalpen. Our NBI often fly to Molln in Summer. On this day the pupils learnt more about this exotic looking visitor and the work of the KLF.

New project granted!

We congratulate Prof. Thomas Bugnyar for his new project Social dynamic and cognition in free living ravens. The project is supported by the FWF.

New students

We welcome our new students!

Tereza Dràbkovà and Kateriná Bìlà from the University of South Bohemia (CZ) and Jakob Gübel from the University of Konstanz (Germany) are working with the ravens.


On October, 20th the new exhibition about the Northern bald ibis will be inaugurate in the Cumberland Game Park. The exhibition provides insights in the recent research on this endangered bird species and presents the results of the cooperation with several schools of the region. It will be open until Spring 2017.

New Students

We welcome our new students!

Jana Beránková and Michaela Syrová from the University of South Bohemia (CZ) and Javier Sierro from Spain are working with the ravens. Tanja Czerny from the University of Vienna started her Masterproject on the Northern bald ibis.

The children of the primary school in Scharnstein were successfully participating in the Sparkling Science Slam by presenting their project Social cohesion and flying behaviour in Northern bald ibis. We congratulate them and wish them a good success at the finale in Vienna on November, 14th.


Biologicum Almtal

From the 6th October to the 9th October the Biologicum Almtal took place for the third time. It was again a great success. Several Austrian scientists from different disciplines engaged on the topic “Feeding and being fed- from competition for food to cooperation.


New Book out!

We congratulate Prof. Kurt Kotrschal for his new book about the close relationship between dogs and humans.

Nature experience day

On august 28th the nature experience day took place in the wild life park for the ninth tine. At many stations could children research and learn something new about animals and plants.

Visitors from Italy

From August the 2nd to 3rd, seven students and Dr. Filacorda from the University of Udine visited us. We were very happy about the reciprocal knowledge and experience exchange and look forward to a future cooperation.


Congratulations for the graduation!

    KinderUniAlmtal (Almtal Children University):

    From July, 20th to 22nd , the third KinderUniAlmtal took place, which was again a great success. 145 children from all over Austria (even from Vienna and Graz) participated to it. They could choose among 5 three-day long courses and nine single workshops. 42 lecturers from all over Austria (e.g. Boku Vienna, University of Vienna, FH Hagenberg and experts of the region) taught the “students” interesting aspects of their area of expertise.

    Approximately 80 kids visited the Konrad Lorenz Research Station and found out exciting facts about flying strategies among animals and social behaviour of greylag geese. Furthermore, they practised modern research by monitoring Northern bald ibises and common ravens.

    Bird ringing programme IMS (Integrated Monitoring of Songbird Populations)

    In this standardised bird-ringing programme, song birds are caught three times a month from May to August six hours a day after sunrise by using mist nets. Data about breeding bird population, age, weight, body measurements and sex are collected. The birds get ringed and immediately afterwards they are set free again.


    Young Talents – Internship for pupils:

    From July, 11th to August, 5th, two high school pupils, Francesca Hemetsberger and Alina Lichtenberg, successfully completed a four weeks internship for pupils at the KLF. Among other activities, they designed posters, recorded the geese’s presence, helped with the ringing of the young birds and collaborate within the KinderUniAlmtal. Their Internship was possible thanks to the programme “Talente Praktika” by the Austrian Research promotion Agency (FFG).
