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...
Distribution of Monitoring Avian Productivity and Survivorship (MAPS) program (www.birdpop.org/maps.htm). The regional outline includes states comprising USFWS Region 3 plus 250km buffer.
This volume's release consists of 26 media files captured by autonomous wildlife monitoring devices under the project, MiddleEarth Wildlife Study. The attached files listed below include several CSV files that provide information about the data release. The file, "media.csv" provides the metadata about the media, such as filename and date/time of capture. The actual media files are housed within folders under the volume's "child items" as compressed files. A critical CSV file is "dictionary.csv", which describes each CSV file, including field names, data types, descriptions, and the relationship of each field to fields other CSV files. Some of the media files may have been "tagged" or "annotated" by either humans...
Chronic industrial noise affects pairing success and age structure of ovenbirds Seiurus aurocapilla.
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...
