In seasonally breeding songbirds, song behavior and neural morphology change seasonally. Song control nuclei are larger during the breeding season, as determined by multiple cytological labels. Seasonal changes in song nuclei are regulated by testosterone (T), and several song nuclei contain intrace

## Abstract Seasonal changes in the concentrations of plasma luteinizing hormone (LH), follicleβstimulating hormone (FSH), and prolactin were measured in serial samples taken from seven captive wild mallard drakes exposed to natural lighting and temperature in Kiel, West Germany (54Β° N), for 20 mon
The Lapland longspur (Calcarius lapponicus) is an arctic-breeding songbird that shows rapid behavioral changes during a short breeding season. Changes in plasma testosterone (T) in the spring are correlated with singing but not territorial aggression in males. Also, T treatment increases song but no
