Point Lepreau Bird Observatory Database

Point Lepreau Bird Observatory Database The Point Lepreau Bird Observatory (PLBO), located in Point Lepreau, New Brunswick, was created as a project of the Saint John Naturalists’ Club (SJNC) in late 1995. The SJNC began accumulating data on bird migration through the Bay of Fundy in spring and fall in 1996. Migration data are collected daily using a sampling method with protocols adapted from Hussell and Ralph (1998). Migration counts using the Hussell and Ralph (1998) count protocol involve a four-hour Count Period consisting of a series of 15-minute counts, each followed by a rest period of equal length. Each Count Period consists of eight 15-minute counts, for a total of two hours, and eight 15-minute periods of rest. Observations are conducted from a permanent observatory building from mid-March to mid-May and from mid-September to mid-November. Observers count all birds seen and since Point Lepreau projects southward into the Bay, birds in spring migration are travelling east when passing it while birds in fall are travelling west. Since the year 2000, counts in spring have been under the supervision of a contracted Official Observer, normally assisted by up to three volunteers. The data are split in to a conditions file and an observations file. The conditions data includes information on weather conditions, sea states and times and durations of each count. The observations data includes observations of birds by species, including numbers of individuals observed and direction of flight. Birds travelling in different directions are recorded separately as are birds resting or feeding on the water. 2024-06-17 Environment and Climate Change Canada enviroinfo@ec.gc.ca Nature and EnvironmentMigrationOrnithologyBirds View ECCC Data Mart (English)CSV https://data-donnees.ec.gc.ca/data/species/assess/point-lepreau-bird-observatory-database/?lang=en View ECCC Data Mart (French)CSV https://data-donnees.ec.gc.ca/data/species/assess/point-lepreau-bird-observatory-database/?lang=fr
