LOCATION DESCRIPTION
The Hubbard Brook Valley bird area has been used extensively for studies of bird populations since the 1970s. The area is forested by typical northern hardwood species (sugar maple, beech and yellow birch) over about 85% of its area, and by patches of red spruce and balsam fir over the remaining 15%.
SAMPLING DESIGN
Each transect point was surveyed three times per year. The starting point and path among points differed for each of the three replicates to minimize the effects of visitation path on time of surveying. First round: valley bottom to ridge. Second round: Ridge to valley bottom. Third Round: mix of valley bottom to ridge and vice-versa. The survey began at 05:30 and was completed before 10:00. A 10 minute survey was conducted at each station, commencing 1 minute after arrival at a point. Surveys were conducted under satisfactory weather conditions: good visibility, little or no precipitation, light winds.
Birds were recorded at two distances: within 50 meters and at 50 – 100 meters. The species of all birds seen and heard were recorded as well as all individual squirrels and chipmunks seen and heard. The 10-minute count was divided into 3 equal intervals (3 minutes, 20 seconds). Periods were numbered as: 1=0–3:20 min, 2=3:21–6:40 min, 3=6:41–10:00min. Each period was treated as a separate count (i.e., Individuals in the later periods were counted even if they were detected in period 1).
New.Record indicates a detection is new for the complete 10-minute count; for example if an individual is detected in the second period and was also detected in the first it received a 0. If it appears for the first time in the second period, it receives a 1. If an individual moves from the outer distance circle (50-100 m) to the 50 m circle during the count, this individual should be marked with a 1 in the New.Record column.
If two male birds were detected simultaneously within 100 m at a count, both individuals received a 1 in the Counter.sing column. These data are critical in that they allow comparison with the point count method prior to 2006.
