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 […]

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 (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 […]

Ovenbird (Seiurus aurocapilla) Science Article 5 abstract Report an observation of a foraging Ovenbird (Seiurus uurocapiZZus) following a ninebandedarmadillo (Dasypus novemcinctus), near Gainesville, Florida. Close attendance only while the armadillo was moving and disturbing leaf litter suggests the Ovenbird was taking advantage of increased prey availability caused by the armadillo’s flushing of insects Douglas J. […]

Ovenbird (Seiurus aurocapilla) Science Article 8 abstract We studied the reproductive ecology of Ovenbirds (Seiurus aurocapillus) for 3 years in a primarily forested landscape in northern Wisconsin. We searched for and monitored nests in large, closed-canopy northern hardwood forests adjacent to recent clearcuts (

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.

Louisiana Waterthrush (Parkesia motacilla) Science Article 2 abstract Cozumel Island is located in the Caribbean Sea between 20 16 and 20 36N and 86 44 and 87 02W, 17.5 km off the northeastern coast of the Yucatan Peninsula. We visited the island monthly from August 1994 to August 1995. During each visit, we performed 25 […]
