A phenominally miniscule "feeding niche"

Red-breasted Nuthatch

Certain birds can share the same tree as a 'food source' by looking at it from a different perspective. The Downy Woodpecker and Brown Creeper, for instance, will hunt for insects while going UP a tree. Conversely a Nuthatch will hunt for insects on the same tree(s) while going DOWN.

All birds find food, and the available food supply is spread out fairly and used efficiently.

What is the magnitude of the oil spill in the Gulf? (Not just the beaches but the whole Gulf)?  For a comparison, the Exxon Valdez oil spill in Alaska in 1989 was 11-million gallons. It's estimated to have killed between 100,000 and 250,000 seabirds.

The recent Deepwater Horizon spill ("leak" actually) let about 210-million gallons of oil pour into the Gulf. Dead birds are still being counted, and more deaths will occur for decades; the bird deaths may total well over a million.
