A Comparison of the Singing Activity of Carolina Wrens <i>(Thryothorus Ludovicianus)</i>) in Urban and Rural Settings
… Understanding how urbanization affects birds’ singing behavior is critical because singing often plays a vital role in attracting mates and defending territories. In addition, as global climate change occurs it will become increasingly important to understand the influence of abiotic factors …

Aspects of song interaction between the closely related bush cricket genera Platycleis and Metrioptera
… one-way and result in inhibition of singing activity by albopunctata, or a change in its song pattern. 'Ibis behaviour was initially described by Broughton in I965 who also described song changes in other species resulting from interactions with singing allospecifics. The present …

Emerging Auditory Selectivity in the Caudomedial Neostriatum of the Zebra Finch Songbird
… sites that do not habituate. During the act of singing, activity changes at the habituating sites becoming nonhabituating with neuronal firing occurring at distinct points in the song. Together, these data suggest the involvement of NCM in the processing of behaviorally significant stimuli both …

Variability in Singing and in Song in the Zebra Finch
… a bird in such a way as to reduce errors while singing. Activity within this nucleus during singing is predominantly uncorrelated with the timing of the song, however a portion of this activity is correlated in such a manner. The modeling experiments consider the possibility that this persistent …

Neuronal FMRP: facilitating learning in a critical brain network for zebra finch song acquisition and regulating synaptic miRNAs spatio-temporally
… show that this variable expression is not due to singing activity alone. Finally, I present preliminary work developing a genetic tool with which to generate a zebra finch model of FXS. In order to study more thoroughly the role of FMRP in neural development, I will then shift focus to the role of …

Low power circuits and systems for wireless neural stimulation
… of HVC led to a strong increase of spiking activity in its downstream target, the robust nucleus of the arcopallium (RA). When this device was used to deliver biphasic pulses of current randomly during singing, singing activity was prematurely terminated in all birds tested. The second …

Variabilität des Reviergesangs des Buchfinken (Fringilla coelebs) zur Raum-Zeit-Beschreibung von Metapopulationen
Der Buchfinkengesang wurde in Potsdam in zwei Hauptpopulationen über drei Jahre aufgenommen. Jedes Individuum wurde eindeutig am individuellen Strophentypenrepertoire identifiziert. Ein weiterer Punkt der die individuelle Wiedererkennung bestätigt ist die hohe Standorttreue der adulten Männchen. …
