A DATA SET is a series of observations collected by the same methodology. Each data set should have documentation sufficient for someone unfamiliar with the research to replicate the study. Data sets may be broken into subsets (data files) that are discrete in space and time, in that order. The documentation for a data set should include all spatial and temporal subdivisions of the data.

DATA SET IDENTIFIER: Grid points bird counts

PROJECT TITLE: Long-term monitoring at 40 points in the LFDP/ Long-term monitoring of avian populations

PROJECT DESCRIPTION: The project is part of the study of the resilience of populations after multiple disturbances. This study uses long-term population measurements of key species as a baseline to evaluate changes in populations in response to disturbance. The distribution of counts at 40 points in the Luquillo Forest Dynamics Plot allows correlation of population changes at each point with changes in plant and animal species and abundance at the same point.

We define a data file as a component of a data set. A data set can have only one data file or more. Basically, different data files have different data structures or format.

DATA SET ABSTRACT: Measurements of bird abundance are taken in the 9 ha grid (5/89 to 6/90) and Luquillo Forest Dynamics Plot (10/90 to present) at El Verde and in Watershed 1 and Whendee Silver's cut plots at Bisley.

DATA SET METHODS: Circular plot counts are used to measure relative numbers of birds over time and between sites. The duration of each count is 10 minutes. During this period, all birds heard or seen are recorded on a data sheet in one of two categories: 1) within 25 m of the observer (< 25 m) and 2) further than 25m from the observer (> 25 m). Records are further broken down into birds only heard (H on the data sheet) and birds observed (recorded as estimated distance from the sampling point in meters; see sample data sheet).

Counts are begun as soon after dawn as possible and conclude before noon. Census points are at least 60 m apart within the grids. A complete list of the grid points where counts are taken is found in the data. Originally counts were conducted three times a year.
