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 Atlantic Bird Observatory - Seal Island station. 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 : 1995
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 and fall
Geographic area covered : From Newfoundland to British Columbia; Member stations in NS, QC, ON (6), MI, MB, SK, AB (3), and BC (2). Pilot stations in NF, PEI, NB, ON, BC and YK.
Type(s) of habitat : Varied, many stations are in coastal locations.
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.
Data format : Data-entry program produces .dbf files. Archival copy of data for most stations is maintained at BSC.
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

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
