MODELING POPULATION GROWTH OF THE OVENBIRD (SEIURUSAUROCAPILLA) IN THE SOUTHERN APPALACHIANS
Ovenbird (Seiurus aurocapilla) Science Article 6 abstract Studies of source-sink dynamics are oft en prompted by concerns aboutnegative population trends. Estimates of population trajectories are usually based onassumptions about survival rates and empirical measures of fecundity. Most modelsignore the infl uence of the rates of renesting and multiple brooding. Andrei L. Podolsky et al, The […]

DISPLAY BEHAVIOR OF OVENBIRDS (SEIURUS AUROCAPILLUS) I. NON-SONG VOCALIZATIONS
Ovenbird (Seiurus aurocapilla) Science Article 4 abstract Although detailed investigations of single displays have furnished insights into their proximate causation and adaptive roles in regulating social behavior (Smith 1977, Sebeok 1977), they contribute relatively little to our understanding of the evolution of animal communication at a somewhat higher level. M. Ross LEIN, W&m Bull., 92(3), […]
Ovenbird response to seismic lines
Ovenbird (Seiurus aurocapilla) Science Article 9 abstract Rapid development of energy reserves in the boreal forest of western Canada hasraised concerns about the potential impacts of forest fragmentation caused by seismic lines. Seismic lines are narrow linear corridors cut by the energy sector to access remote areas. Traditionally, seismic lines were cut using a bulldozer […]
Population crash of the ortolan bunting Emberiza hortulana in agricultural landscapes of southern Finland
Ortolan Bunting (Emberiza hortulana) Science Article 1 abstract The ortolan bunting Emberiza hortulana is a bird species that has shown a particularly dramatic decline during recent decades within the agricultural areas of Europe. We studied the population density changes and environment associations of the ortolan bunting within agricultural landscapes in southern Finland, from territory to […]

Recognition of individuals of Ortolan Bunting Emberiza hortulana using image processing procedures
Ortolan Bunting (Emberiza hortulana) Science Article 3 abstract The method of individual recognition of Ortolan bunting Emberiza hortulana songs using simpleimage processing procedures was developed and tested. The method efficiency for the training data set was95% and for independent, testing data set 67%. Besides recognition of individuals, the method enablesselection of song elements, which can […]

Structure and repertoire variation in ortolan bunting (Emberiza hortulana L.) from isolated Norwegian population
Ortolan Bunting (Emberiza hortulana) Science Article 2 abstract This paper describes song structure and repertoire variation in ortolan buntings (Emberiza hortulana) from an isolated and declining Norwegian population, analysed by using the minimal unit of production approach. Males from the studied population sang strophes similar to both dialects found in geographically closest populations in Sweden. […]
