Poisonous, and in our back yard

Lobelia inflata is an "acrid poisonous annual is found in a variety of sites, often in poor soil. The American Indians were said to have smoked and chewed its leaves; hence the common name. Though once used as an emetic, the root should not be eaten, for if taken in quantity it can be fatal."

A lone slender stalk of Indian tobacco, growing on the east side of the shed in our back yard.  What bird was responsible for bringing that seed onto that ground?
