Descripción

Vermont LoonWatch was initiated in 1983 to provide an annual, mid-summer estimate of the statewide Common Loon (Gavia immer) population. It is managed by the Vermont Center for Ecostudies and the Vermont Fish and Wildlife Department. On the third Saturday in July each year, volunteers survey assigned lakes, ponds, and reservoirs from 8:00 to 9:00 AM, recording the number of adult, subadult (1-2 year old loons), and loon chicks on the waterbody, as well as relevant human and wildlife activity. Observers on lakes larger than 300 acres were allowed a longer survey period. Data were recorded on standardized forms and returned to the VLRP biologist for summarization via standard mail or e-mail, or submitted to Vermont eBird.

Datos del proyecto

The LoonWatch Project is an annual census of Vermont's Common Loon population. LoonWatch is a long term Community Science project which relies on trained volunteers to conduct the census.

Título Vermont LoonWatch
Identificador VermontLoonWatch
Fuentes de Financiación LoonWatch is funded by a variety of sources, including state and federal grants, private donors, and wildlife restoration projects.
Descripción del área de estudio LoonWatch is focused on the lakes, ponds and reservoirs of Vermont that are likely to harbor breeding loons. The specific water bodies surveyed each year vary slightly based on the availability of community scientists.

Observers on lakes larger than 300 acres were allowed a longer survey period. Data were recorded on standardized forms and returned to the VLRP biologist for summarization via standard mail or e-mail or submitted to Vermont eBird. The information has provided an annual statewide population estimate, an estimate of the number of non-breeding loons, and a check on lakes with previously undetected breeding pairs.

Métodos de muestreo

The LoonWatch sampling protocol is to perform timed area-surveys of Vermont's known or potential Common Loon nesting habitats - water bodies having adequate takeoff and landing area, sufficient water depth, and minimal threats to nest-viability. Surveys are conducted on the third Saturday of July where lakes smaller than 300 acres are surveyed from the water for one hour between 8:00 and 9:00 AM. Lakes larger than 300 acres are surveyed from the water for 1-4 hours between 6:00 and 10:00 AM. Timed observations are made by trained volunteers from shoreline or boats making transects to sample each water body. Observers record only the first observation of each specific individual, and make note of transient individuals without counting them. Observers record the time, location, and direction of movement of each counted individual or group of individuals. The resulting tallies for each water body by life stage - adult, sub-adult, and chick - comprise the output of LoonWatch surveys.

Área de Estudio LoonWatch is an annual census of breeding Common Loons that inhabit water bodies in the state of Vermont during breeding season.
Control de Calidad The Vermont Loon Recovery Project biologist reviews the data each year.

Descripción de la metodología paso a paso:

  1. LoonWatch surveys are conducted using a standardized survey format, and are recorded on paper or entered into Vermont eBird. LoonWatch is a dedicated project on Vemont eBird, where a specific survey type was added - LoonWatch - to facilitate the recording of Common Loon survey observations. LoonWatch survey results are sent to project biologists who record those data for each water body surveyed with counts for each Common Loon life stage - adult, sub-adult, and chick. Surveys finding zero Common Loon inhabitants on a water body during a survey are recorded as absent. LoonWatch survey data are tallied and retained in spreadsheets by year, and those spreadsheets provide the source data for this resource.
