Retrieved from the Data Repository for the University of Minnesota. --------------------- DATA & FILE OVERVIEW --------------------- 1. File List A. Filename: Point_Count_Data.csv Short description: Raw point count data collected on urban birds during the breeding season. B. Filename: Point_Count_Observation_Summaries.csv Short description: Summaries of point count observation periods (160 sampling efforts in all). C. Filename: Methods for Bird Point Counts from Downtown Minneapolis.pdf Short description: Brief report describing study area, ethics statement, and field methods for collection of point count data. D. Filename: PtCountPoints.zip Short description: Vector layer with 16 point count locations. E. Filename: PtCountBuffers.zip Short description: Vector layer with 50-meter buffers around 16 point count locations. 2. Relationship between files: Primary data are in "Point_Count_Data.csv". Each record is a bird detected via conventional point count protocol. The "Point_Count_Summaries.csv" file is a complete documentation of sampling efforts. The summary spreadsheet is important because some point count observations resulted in zero observed birds, and therefore, those efforts are not represented in the "Point_Count_Data.csv" file. The summary spreadsheet also contains aggregate bird counts that were derived from "Point_Count_Data.csv". The PDF report describes the site of data collection and field methodology. It also includes a figure (i.e. map) illustrating the site and a short bibliography. The zipped shapefile data contain point count locations (16 in all) and their corresponding transect areas (50-meter buffers). 3. Additional related data collected that was not included in the current data package: I collected data on bird-building collisions via daily surveys. Those data are not published. 4. Are there multiple versions of the dataset? no -------------------------- METHODOLOGICAL INFORMATION -------------------------- 1. Description of methods used for collection/generation of data: See PDF titled "Methods for Bird Point Counts from Downtown Minneapolis, 2016 Breeding Season". 2. Methods for processing the data: Field data were converted from Excel files to .csv files. I created a vector layer in ArcMap Version 10.4 in order to digitize point count locations using a spatial reference system. 3. Instrument- or software-specific information needed to interpret the data: Zipped shapefiles can be read in ArcMap by ESRI 4. Standards and calibration information, if appropriate: none 5. Environmental/experimental conditions: none 6. Describe any quality-assurance procedures performed on the data: Data were transcribed from paper datasheets and then proofed. AA completed all steps because there were no technicians available to cross-validate work. 7. People involved with sample collection, processing, analysis and/or submission: Abigail Anderson with guidance from Dr. Rob B. Blair. ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: "Point_Count_Data.csv" ----------------------------------------- 1. Number of variables: 10 2. Number of cases/rows: 1497 (every case is a single bird) 3. Missing data codes: All missing values are indicated with a ".". 4. Variable List (spreadsheet contains header row) A. Name: observationID Description: Indicates the observation period (i.e. a 6-minute point count) during which a bird datapoint was recorded. This variable has 160 unique values. Values are concatenated terms, composed of a letter (single character) representing the location, followed by numerals (2 digits) which identify the observation period as first, second, third (etc.) within a sequence of 10 observation periods. Example: S03 is the third of 10 observations at the location named "S". B. Name: date Description: Date on which bird was observed. M/D/YYYY C. Name: starttime Description: Time at which the 6-minute observation period started. H:MM (All values are a.m. and no observations were made after noon.) D. Name: PointID Description: Name of the point at which observation was made. This variable has 16 unique values: B, C, D, F, G, I, J, M, N, O, P, R, S, T, U, V. Note: There were no points named A, E, H, K, L, or Q. E. Name: cloud Description: Proportion of cloud cover during observation period. Values: 0 (clear skys); 0.25 (25% cloudy); 0.5 (50% cloudy); 0.75 (75% cloudy); 1 (no clear skies); and "." (no data) F. Name: wind Description: Ordinal value which approximates wind during observation period. Values: none, slight, moderate, strong, and "." (no data) G. Name: detect_time Description: Time at which individual bird was detected within the 6-minute observation period. M:SS Possible (ie valid) values range from 0:00 (detected at start time) to 5:59 (detected at 5 minutes and 59 seconds into observation period). H. Name: spp Description: Species of the individual bird, recorded using 4-letter codes per AOU (2015). All values are listed below with common and scientific names. AMCR: American Crow, Corvus brachyrhynchos AMRO: American Robin, Turdus migratorius BCCH: Black-capped Chickadee, Poecile atricapillus CANG: Canada Goose, Branta canadensis CHSW: Chimney Swift, Chaetura pelagica COGR: Common Grackle, Quiscalus quiscula EUST: European Starling, Sturnus vulgaris GBHE: Great Blue Heron, Ardea herodias HOFI: House Finch, Haemorhous mexicanus HOSP: House Sparrow, Passer domesticus PEFA: Peregrine Falcon, Falco peregrinus ROPI: Rock Pigeon, Columba livia WTSP: White-throated Sparrow, Zonotrichia albicollis I. Name: detect_distbin Description: Distance from observer when bird was detected. Distances were estimated and lumped into bins, as follows: "5" means >0 and < or =5 meters from observer "10" means >5 and < or =10 meters "15" means >10 and < or =15 meters "20" means >15 and < or =20 meters "25" means >20 and < or =25 meters "30" means >25 and < or =30 meters "35" means >30 and < or =35 meters "40" means >35 and < or =40 meters "45" means >40 and < or =45 meters "50" means >45 and < or =50 meters "." means no data. This value us used for "flyby" birds which were detected flying through the buffer transect area and not seen "using" the area. J. Name: detect_how Description: Categorical variable describing how the bird was detected (first detection). Meaning, for a bird first detected by ear and later seen, the data value will be "Aud". 3 values: "Aud" for auditory; "Vis" for visual; and "Flyby" for a bird seen flying through the buffer transect area. Note: Per conventional point count protocols, "Aud" and "Vis" detections denote birds assumed to be using the area. Note: Per conventional point count protocols, "Flyby" detections denote birds only passing through and cannot be assumed to be using the area or members of the local bird community. Note: "Flyby" records are incidental, yet they may be of interest and the analyst may exercise discretion regarding their use and interpretation. Some species (eg PEFA and CHSW) are not likley to be detected within a transect area owing to their behaviors. ----------------------------------------- DATA-SPECIFIC INFORMATION FOR: "Point_Count_Observation_Summaries.csv" ----------------------------------------- 1.
