EDMONTON JOURNAL JULY 17, 2012 Re: “Lyme-carrying ticks here, researcher says,” the Journal, July 11.

The presence of the blacklegged tick in Alberta is not a new revelation.

Many years ago, our research team documented the first record of this tick species on a Swainson’s Thrush in Alberta, collected on May 19, 1998. In fact, we have reported blacklegged ticks collected from birds in Alberta in two peer-reviewed scientific journals, in 2001 and 2005 respectively.

In the Journal article on his research, Daniel Fitzgerald at the University of Alberta said it was possible that climate change is a factor for blacklegged ticks in Alberta. But there is no mention that migratory songbirds play an integral role in wide dispersal of bird-feeding ticks.

Weather data for Edmonton listing the mean daily temperatures during the past 50 years show climate change has nil or no effect on blacklegged tick survival in Alberta.

The provincial government and the medical profession have been oblivious to what is happening in nature while songbirds introduce Lyme disease vector ticks into Alberta each year.
