CMMN Daily Estimated Totals: Long Point Bird Observatory

Bird Studies Canada
http://www.bsc-eoc.org

Project name: Canadian Migration Monitoring Network

Goals : To generate counts of migrating birds for use in long-term population monitoring, especially landbird species not monitored by current breeding or winter surveys; To carry out cooperative research projects on the ecology of migrating birds.

Dataset summary : This dataset contains daily estimated totals (DET) from the Long Point Bird Observatory (Tip, Breakwater and Old Cut stations). DET is a standard protocol used by Canadian Migration Monitoring Network stations to estimate the total number of individuals of each species occurring at a site during migration.

Status : Active

Year started : 1960

Years (comments) : CMMN was launched in 1998 as an ongoing monitoring program. The first migration monitoring station in North America was LPBO, started in 1960.

Season(s) and frequency : Spring monitoring runs from April 1st to June 10 and fall monitoring runs from August 1 to November 15.

Geographic area covered : Located near Port Rowan, Ontario (42.583451░, -80.396535░).

Type(s) of habitat : Count area includes Woodland, Shrubland, Open wetlands (marsh, bogs, etc.), Standing water (pond, lake), and Beach or dunes.

Primary species covered : Primary focus is landbirds (104 priority species) but some stations also monitor waterbirds, raptors.

Sampling Design : Standardized captures and observations used to derive daily estimated total throughout migration window.

Field methods : Combination of standardized daily captures, census, visible migration counts and other observations resulting in a daily estimated total for each species. Count period is during daylight hours, with a 1 hour census.

Data format : Scanned log sheets are processed into an Access database and then moved to SQL server

Data update frequency : Usually once or twice a year (last update includes fall 2007)

Sample size : 16 full member station operating 21 migration stations. Several pilot stations.

Results : Most stations produce some form of annual report for members.

Trends and time series availability : Time series varied (1960-present for LPBO). Trend graphs updated annually for all stations with at least 5 years of data. Available on BSC web site

Publications : Hussell, DJT and CJ Ralph. 1998. Recommended methods for monitoring bird populations by counting and capture of migrants. (available on BSC website) Dunn, EH and DJT Hussell. 1995. Using migration counts to monitor landbird populations: review and evaluation of current status. Pp 43-58 in D.M. Power (ed.), Current Ornithology vol 12. Plenum Press, NY.

Funding sources : Varied.

Applications for the data : Trend information feeds into integrated population approach and is also used for planning and environmental assessment purposes.

Users of the information : BSC, research biologists
