Ovenbird - VizBand/Land AIC Model Selection Created: 03-Jun-2011 Ovenbird annual capture rate of adult (ADULT) individuals (log transformed) ranged between -0.242 and +2.565 with a mean value of +1.161 and a median value of +1.070. ________________________________________ Model 1 (2 parameters) Ovenbird annual capture rate of adult (ADULT) individuals (log transformed) was a function of: a) NLCD06AF5KP (+0.01197) - percent all forest cover, 990m-resolution in a landscape context of 5km radius, ranged between +8.078 and +113.833 (95% CL) with a mean value of +60.956 and a median value of +69.449, b) GTOPO30_AL (+0.00122) - elevation (m), ranged between -35.468 and +696.689 (95% CL) with a mean value of +330.610 and...

Conclusions: There was a significant reduction in ovenbird pairing success at compressor sites (77%) compared with noiseless wellpads (92%). These differences were apparent regardless of territory quality or individual male quality. Noise interferes with a male's song, such that females may not hear the male's song at greater distances and/or females may perceive males to be of lower quality because of distortion of song characteristics Thresholds/Learnings: Synopsis: Anthropogenic noise is rapidly increasing in wilderness areas as a result of industrial expansion. This study assessed pairing success and age distribution of male ovenbirds, Seiurus aurocapilla, in the boreal forest of Alberta, Canada, in areas around...

Conclusions: Increasing seismic line density from 0 to 8 km/km2 resulted in a 38% decline and an 82% decline in bird abundance when individuals used lines as territory boundaries or avoided edges by 50 m, respectively. When tested with ovenbirds, male ovenbirds showed a distinct use of one side of the seismic line, suggesting lines acted as territory boundaries. Ovenbirds declined with seismic line density when a threshold seismic line density of 8.5 km/km2 was reached. Above the threshold, Ovenbirds declined 19% for each 1 km/km2 increase in seismic line density. Thresholds/Learnings: Synopsis: In the boreal plains of Alberta, Canada, energy sector exploration has resulted in extensive dissection of the landscape...
