Folks I've been asked about the Source of my recent letter concerning
tick-carrying birds. Herewith, the entry in its entirety:

"Several recent studies demonstrate that wild birds transport ticks and
their associated diseases during migration. In addition, a number of bird
species are able to contract Borrelia burgdorferi, the bacterium causing
Lyme disease, and transport it to uninfected ticks that parasitize the
birds for a blood meal. Ground feeding species (cardinals, catbirds, song
sparrows, robins) spend a significant amount of time foraging for food at
optimal height for ticks, and are excellent hosts and have all demonstrated
the ability to infect ticks with the Lyme-disease causing bacteria.
