R Soc Open Sci . 2017 Oct; 4(9):170652. PMID: 28989768
A range of non-human animals frequently manipulate and explore objects in their environment, which may enable them to learn about physical properties and potentially form more abstract concepts of properties...

OHara M, Schwing R, Federspiel I, Gajdon G, Huber L
Anim Cogn . 2016 May; 19(5):965-75. PMID: 27209174
Reasoning by exclusion, i.e. the ability to understand that if there are only two possibilities and if it is not A, it must be B, has been a topic of...

Vet Microbiol . 2016 Jan; 183:135-9. PMID: 26790946
Six kea (Nestor notabilis) in human care, naturally infected with West Nile virus (WNV) lineage 2 in Vienna, Austria, in 2008, developed mild to fatal neurological signs. WNV RNA persisted...

Auersperg A, Gajdon G, von Bayern A
Commun Integr Biol . 2012 Jul; 5(2):140-5. PMID: 22808317
Comparative cognition aims at unfolding the cognitive processes underlying animal behavior and their evolution, and is concerned with testing hypotheses about the evolution of the brain and intelligence in general....

Auersperg A, von Bayern A, Gajdon G, Huber L, Kacelnik A
PLoS One . 2011 Jun; 6(6):e20231. PMID: 21687666
Parrots and corvids show outstanding innovative and flexible behaviour. In particular, kea and New Caledonian crows are often singled out as being exceptionally sophisticated in physical cognition, so that comparing...

Auersperg A, Huber L, Gajdon G
Biol Lett . 2011 Jun; 7(6):825-8. PMID: 21636657
This study depicts how captive kea, New Zealand parrots, which are not known to use tools in the wild, employ a stick-tool to retrieve a food reward after receiving demonstration...

Liedtke J, Werdenich D, Gajdon G, Huber L, Wanker R
Anim Cogn . 2010 Sep; 14(1):143-9. PMID: 20814805
The trap-tube task has become a benchmark test for investigating physical causality in vertebrates. In this task, subjects have to retrieve food out of a horizontal tube using a tool...

Miyata H, Gajdon G, Huber L, Fujita K
Anim Cogn . 2010 Jul; 14(1):45-58. PMID: 20640911
Keas, a species of parrots from New Zealand, are an interesting species for comparative studies of problem solving and cognition because they are known not only for efficient capacities for...

Schloegl C, Dierks A, Gajdon G, Huber L, Kotrschal K, Bugnyar T
PLoS One . 2009 Aug; 4(8):e6368. PMID: 19654864
Background: Among birds, corvids and parrots are prime candidates for advanced cognitive abilities. Still, hardly anything is known about cognitive similarities and dissimilarities between them. Recently, exclusion has gained increasing...

Auersperg A, Gajdon G, Huber L
Biol Lett . 2009 May; 5(4):455-8. PMID: 19411271
The 'Support Problem' is a benchmark test to investigate the understanding of spatial relationships between objects. We tested kea parrots' performance in a paradigm that has previously been studied in...
