Langmore Group - Avian evolutionary and behavioural ecology

We study many aspects of evolutionary and behavioural ecology in birds, with particular emphasis on co-evolution between brood parasites and their hosts, signalling (songs, calls and displays), mimicry and crypsis, breeding systems, and evolutionary responses to climate change. Our main approach is to use field experiments and observations to test evolutionary theory.

E&E PhD Exit Webinar: Conservation and management of the forty-spotted pardalote

Event | Thu 6 May 2021
Despite conservation efforts, the number of species that have recovered after management remain small. Low success rate in species management can be attributed to severe lack of funding for conservation and ‘evidence complacency’ (i.e. use of anecdotes rather than evidence) by many conservation practitioners.

E&E PhD Exit Seminar: Cracking egg investment: maternal investment strategies in cuckoos and their hosts

Event | Fri 4 December 2020
Individuals can benefit by varying their investment in offspring. The optimal amount of investment may vary in relation to both climatic conditions and social conditions (such as the number of carers for the offspring).

E&E PhD Exit Seminar: An imposter in the nest: rejection of cuckoo chicks by a host using true recognition

Event | Fri 9 August 2019

Interactions between avian brood parasites and their hosts are one of the most suitable model systems for studying coevolution.

Move over magpies: are cuckoos the meanest bird?

Story | Monday 13 September 2021
Since it’s Bad Bird Season, we ask cuckoo apologist - sorry, cuckoo expert - Professor Naomi Langmore to explain how it could possibly be that the cuckoo doesn’t mean to be mean, when it sure looks like it does.

Only the lonely: an endangered bird is forgetting its song as the species dies out

Story | Thursday 18 March 2021
In healthy populations, the song of regent honeyeaters is complex and long. But where the population is very small, the song is sadly diminished.

Researchers help endangered birds beat deadly parasite

Story | Wednesday 12 August 2020
Researchers have found a way to help one of Australia’s rarest birds ‘self-fumigate’ their nests, to protect their young from parasites.

Wait - We're sexist towards birds now?

Story | Tuesday 1 October 2019
Five years ago, an ANU biologist proved that most female songbirds sing, but it’s a finding that many people are struggling to accept.

Study reveals how a mother always knows her chicks

Story | Thursday 7 June 2018
A study led by ANU has discovered how a mother knows her chicks and can spot an imposter in her nest, even if it looks almost identical to her own chicks.

ARC grant success

The Australian National University (ANU) has won $24 million in Australian Research Council (ARC) funding for 58 research projects across the University. 

Fairy wrens vary egg size to increase survival rates

Story | Thursday 1 December 2016
The female Superb Fairy-Wren has the ability to change the size of the eggs it lays, a biological feat which could buffer against the effects of climate change.
