| To some extent, the sample sizes reflect the relative abundances of the host species on each island. |
| Of recently naturalized species, some have rapidly changing ranges and rapidly changing local abundances. |
| Hintze gave qualitative estimates of relative species abundances at particular sampling horizons, but did not list total sample sizes. |
| We document relative abundances, habitat preferences, and foraging guilds for the members of the bird community. |
| Other important factors influencing bird abundances were food availability and events in the migratory and winter periods. |
| Functional group abundance was calculated by summing the abundances of all species in a particular group on a sample date. |
