Listened to this while driving home fromN.B.
Very interesting.

From Quirks & Quarks on CBC, listened to this driving home from N.B. Totally interesting how the birds have adapted to keep tics and fleas away from their young.

We found, funnily enough, exactly what we expected - that the birds had added significantly more cigarette butts in the nests where we had added the live ectoparasites than the other treatments.

They use cigarette butts as nesting material. When their nest is infested they add more material, hence more cigarette butts. So a more valid indicator would be the ratio of butts to other material added. I presume they thought of that and it's just the article isn't clear.
But yeah, I can see that nests with more butts would be more successful, and the offspring would tend to use the material that they grew up in, introducing a positive selection pressure for the species. But that's different than individual birds figuring it out as an anti-parasite strategy.
