It's possible that your feeder may contribute to tick transmission,
but probably not significantly. Ticks on birds eventually fall off
and drop to the earth, where they lay their eggs that hatch out into
immature ticks that eventually get back primarily onto ground-feeding
birds--sometimes after spending part of the life cycle on small
mammals. That said, ticks can get onto birds as larvae, nymphs, or
adults, but it seems less likely that a tick already on one bird
would jump to another bird at the feeder.
In my experience as a bander, mild winters seem to lead to greater
infestations of ticks. It's part of the natural scheme and nothing to
be alarmed about.
In the past I have caught birds with a dozen or more ticks on their
heads, and many of the birds were recaptured later will no ill
effects. (I used to remove ticks from birds when I banded them, but
quit doing it because I thought it did more harm than good.) Ticks
can have a detrimental effect on birds, however, including causing
temporary or permanent blindness and, in extreme cases, even death
when several ticks divert blood from the bird's brain.
Some of my experiences with bird and ticks are described on the
Hilton Pond Center's website at http://www.hiltonpond.org. I've just
posted two tick articles with color photos under the "Publications"
subsection; one is under Vol. 3 of "The Piedmont Naturalist," the
other is under "General Articles."
BTW, ticks or no ticks, it's a good idea to clean all your seed
feeders monthly, sterilizing them with a light concentration of
household bleach.
Best wishes,
