April 8-14 2004
This is an update on Migration Monitoring results from Tommy Thompson
Park for the week of April 8th-14th, 2004.

Northern winds continued throughout the update period and as a result,
landbird migration has been very light in Southern Ontario. American
Robin, Brown-headed Cowbird, Red-winged Blackbird and Song Sparrow
were the most abundant species detected during the week (not including
Gulls and Cormorants of course!). Staff and volunteers of TTP Bird
Research Station did manage to find 27 new species for the spring
season, which includes a few new species for the project.
