Book of Birds
Book of Birds is a composition for flute and electronics inspired by birds. Throughout human history, artists have developed stories and music about the natural world around them. In this piece, Book of Birds, I am adding to this vast repertoire of folk stories with some of my own design, focusing …

Cities for birds, birds for cities: The urban ecology of birds across scales from global sampling to individual responses
… worldwide, yet our ability to understand how birds persist in cities is limited by biased data and a focus on coarse occurrence patterns. This thesis examines the urban ecology of birds across scales, from a global standardized monitoring framework to city-level drivers of species prevalence …

Call Combinatoriality in Birds
… diversity of vocal communication systems across birds not only reflects considerable variation in repertoire size, but also in the organisation of acoustic elements, both within and across calls. A fundamental challenge for understanding this variation lies in the subjective nature of call …

A Currency of Birds
<p>This collection of poetry narrates the experience of woman who has arrived in a desert city without memory of her arrival or her past. The poems explore presence through absence, loss, longing, fragmentation, and the construction of identity.</p>

Woody cover and birds
… structure on the distribution and abundance of birds. Changes in habitats due to an increase or decrease in woody cover has been linked to changes in bird diversity and community structure. This thesis looks at what impacts bush encroachment has had on bird distributions in eastern South Africa, …

Magnetic orientation in migratory birds
Wie nehmen Zugvögel das Magnetfeld wahr und wie nutzen sie diese Information, um sich zur Zugzeit zu orientieren? Das sind die Schlüsselfragen meiner Doktorarbeit. Cryptochrome werden als potentielle Magnetfeld-Rezeptoren vorgeschlagen. Ich konnte vier Cryptochrom-Varianten in der Retina von …

Evidence for Local Adaptation in Birds
… two, we review evidence for local adaptation in birds. Geographic variation among populations is nearly ubiquitous, yet experimental tests of the fitness advantages of local trait variants are rare among populations of birds, presumably because of the difficulties in transporting individuals …

This Art Is For The Birds
I use bright colors to portray birds. Typically, the birds are modeled after herons, peacocks, woodpeckers, and roadrunners. I am interested in the curvilinear forms or colorful plumage of these birds. Why birds? I wonder that myself. The rational part of me wants to know why I use bird imagery, …

Hormonally mediated maternal effects in birds
… environment are transmitted to the offspring in birds via egg compositional changes. It is possible that maternally derived hormonal signals communicate information about the external environment to developing embryos and directly influence the fitness of their offspring in a negative or positive …

The Allometry of Giant Flightless Birds
Despite our intuition, birds are no smaller than mammals when the constraints of a flying body plan are taken into account. Nevertheless, the largest mammals are ten times the mass of the largest birds. Allometric equations generated for anseriforms and ratites suggest mid-shaft femur circumference …

Speciation Genomics in Australian Meliphagoid Birds
The speciation process proceeds through a continuum of increasing genomic divergence and decreasing gene flow between populations. While sampling across hybrid zones provide insight for an intermediate stage of speciation, comparative studies of multiple contact zones between populations at …

Food intake in birds: hypothalamic mechanisms
