This female Cerulean Warbler was banded this morning at TTPBRS. This is the first record of the species for TTPBRS and to my knowledge the first observed at Tommy Thompson Park/Leslie Street Spit in at least 5 years. The Cerulean Warbler is considered the fastest declining warbler on the continent. Forest loss and fragmentation are key concerns for the future of the species and it is remarkable that they are still not listed as threatened in the endangered species act. The second Ontario Breeding Bird Atlas documented significant declines of Cerulean Warblers in Ontario since the early 1980's.
