Birds have radicaly different respiratory systems, compared to igs and mammals. They have lungs, and a series of interconnected airsacks, some of which are inside their hollow bones. They are extremely efficient in processing air, because of the high enery demands during filght. This is also coupled with their extremely high metabolism, another flight adaptation. Any toxins they breathe are absorbed very rapidly, and quickly processed by their body, so the toxin takes effect much sooner than it would with a bird or a reptile.

From what I remember from my herpitology texts, Igs have rather simple lungs, and slow metabolism. Of the three (bird, human, ig) the ig would take the longest to absorb enough toxin to reach lethal levels.

Hope that helps. Here are two texts on bird respiratory systems:
