Ovenbird (Seiurus aurocapilla) Science Article 2 abstract In 1990 and 1991, we determined the proportion of Ovenbird (Seiurus aurocapillus)territorial males that were paired in a 25-ha plot in an extensive forest (>350 km 2) inQu6bec, and compared it to pairing success in populations breeding in nearby forest fragments (4.5-53.0h a) in Quebec and Ontario.

HABITAT FRAGMENTATION AND PAIRING SUCCESS IN THE OVENBIRD (SEIURUS AUROCAPILLUS)
Ovenbird (Seiurus aurocapilla) Science Article 2 abstract In 1990 and 1991, we determined the proportion of Ovenbird (Seiurus aurocapillus)territorial males that were paired in a 25-ha plot in an extensive forest (>350 km 2) inQu6bec, and compared it to pairing success in populations breeding in nearby forest fragments (4.5-53.0h a) in Quebec and Ontario.

FOREST PRODUCTIVITY PREDICTS INVERTEBRATE BIOMASS ANDOVENBIRD (SEIURUS AUROCAPILLUS) REPRODUCTION INAPPALACHIAN LANDSCAPES
Ovenbird (Seiurus aurocapilla) Science Article 1 abstract Forest-floor detrital food webs are sustained by annual inputs of leaf fall.However, it is unknown whether this bottom-up effect extends to vertebrates feeding onthe detrital food web. We hypothesized that reproductive success of Ovenbirds (Seiurusaurocapillus L.) is a function of macroinvertebrate biomass within the detrital food web,and that […]
Identifying Ovenbird (Seiurus aurocapillus) habitat in a suburbanizing landscape: The use of GIS and regional landscape approaches in conservation
Ovenbird (Seiurus aurocapilla) Science Article 3 abstract To conduct a repeatable process for detecting the presence or absence of the Ovenbird inpotential habitat patches within the seven county Triangle Region of North Carolina (Chatham,Franklin, Lee, Durham, Orange, Johnston and Wake).

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), […]
Lek size variation and its consequences in the ochre-bellied flycatcher, Mionectes oleagineus
Ochre-bellied Flycatcher (Mionectes oleagineus) Science Article 1 abstract Several hypotheses suggest that the costs and benefits of display in aggregations of different sizes play a major role in both the evolution of leks and in the distribution of males across lekj of different sizes. We examined the consequences of variation in lek size for both […]
Differential timing of spring migration in northern wheatears Oenanthe oenanthe: hurried males or weak females?
Northern Wheatear (Oenanthe oenanthe) Science Article 2 abstract In a field experiment on the island of Helgoland (southeast North Sea), we investigated whether migration strategy or competition between the sexes cause the differential timing of spring migration of male and female northern wheatears (Oenanthe oenanthe) (males migrating earlier). The study included two subspecies, heading towards […]
MAGNETIC ORIENTATION OF MIGRATORY WHEATEARS(OENANTHE OENANTHE) IN SWEDEN AND GREENLAND
Northern Wheatear (Oenanthe oenanthe) Science Article 5 abstract Orientation experiments were performed with wheatears (Oenanthe oenanthe) subjected to artificially manipulated magnetic fields, in Sweden and Western Greenland, during the autumn migration period. The objective was to compare responses by birds exposed to widely different geomagnetic conditions and, specifically, to clarify if birds are able to […]
