Migration Monitoring at TTP - August 19-25

The drought continues....
Bird numbers remained low at Tommy Thompson for the third week of fall coverage, which is typical for mid-late August. The peak for Waxwings, Catbirds, and Yellow Warblers has now passed and we are now awaiting more northerly breeding songbirds. Warblers are just starting to show up in southern Ontario and we are hoping for a better showing for most warbler species this fall. However, recent reports of poor breeding conditions for boreal and arctic breeding birds may be reflected in our banding and census totals at TTP this fall.
Time will tell....
