From Table: Animal Companion Base Statistics it appears that animal companions get multiattack at 9th level. What does this mean for a bird with a bite and two talon attacks? It looks like these are all primary attacks (same BAB) so the bird would get one additional attack at BAB -5 at 9th level. Or should it be that for levels 1 - 8 the bird should be attacking bite at BAB and talons BAB -5 so that multiattack would reduce the deficit for the secondary attacks to BAB -2? Thanks!
