Dr Gabriel A. Jamie

Biography:

I am a post-doctoral research associate in the Department of Zoology at the University of Cambridge.

A love of natural history is at the core of my work. I became interested in science as a child through watching birds, first in Cape Town and then in UK. This has led to a life-long avian obsession that has taken me to do fieldwork on birds around the world - including in Peru, Ghana, Zambia, South Africa, Mozambique, Greece and Romania.

Research Interests

Mimicry and speciation in the parasitic finches of Africa

I study the nature of biological diversity and the processes that generate it. I focus particularly on speciation, mimicry and the role of learning in generating novel adaptations. The brood-parasitic indigobirds and whydahs (Vidua spp.), which I researched for my PhD, are a brilliant system for investigating these topics. My work uses a mixture of natural history observation, behavioural experiments, bioinformatics and lab work to study the radiation of Vidua and their host species, particularly focusing on what limits the former’s diversification.

The hosts of the Vidua finches, the Estrildidae, possess arguably the most spectacular mouthpart ornamentation of any group of birds (see photos). These markings are important signals in mediating parent-offspring interactions. In collaboration with Professor Michael Sorenson (Boston University) and Professor Rebecca Kilner (University of Cambridge), I am studying the evolution of these mouthpart markings across the family.

Even more remarkably, the nestlings of the parasitic indigobirds and whydahs exhibit mouthpart markings that are near-perfect matches of their host’s. In collaboration with Dr Jolyon Troscianko (Exeter University) I am quantifying this similarity from an avian visual perspective. Additionally, with Professor Michael Sorenson (Boston University) and Dr Chris Balakrishnan (University of North Carolina), I am using next-generation sequencing approaches to understand the molecular basis of this mimetic convergence.

The evolution of egg diversity in prinias

I am currently a BBSRC-funded post-doctoral research associate at the University of Cambridge. My current work focuses on the interactions between the brood-parasitic Cuckoo Finch (Anomalospiza imberbis) and its Tawny-flanked Prinia (Prinia subflava) hosts. Prinias have evolved incredibly diverse eggs which vary dramatically in colour and pattern between individuals. In collaboration with Professor Michael Sorenson of Boston University and Professor Claire Spottiswoode of Cambridge/University of Cape Town, I am currently investigating the genetic basis of this diversity and the consequences of this genetic architecture for the co-evolutionary trajectories in the ongoing arms race between prinias and their Cuckoo Finch parasites.

Ornithological exploration and conservation in Africa

I am involved in ornithological expeditionary work and the conservation of African birds. I am a Research Associate at the FitzPatrick Institute of African Ornithology at the University of Cape Town (http://www.fitzpatrick.uct.ac.za/fitz/staff/research/jamie).

In November 2016, I was part of an expedition to the Njesi Plateau in northern Mozambique with researchers from BINCO. Together with Sam Jones, we discovered new populations of the highly endangered Mozambican Tailorbird (Artisornis sousae) and Dapplethroat (Modulatrix orostruthus) as well as finding two species previously unrecorded from Mozambique.
