Bird Population -- any estimates out there?

100 billion, according to this estimate:

20 birds for every person

Personally, I am happy to report that I did my part to cut down on the bird population last Thanksgiving.

Colonel Sanders should be very happy about that - does this include chickens. 20 per person seems low since the average american eats 50 lbs of chicken per year.

23 Million chickens are killed each day:

I don't know about domestic birds... However the average American is not the average worldwide inhabitant, who probably eats 5 chickens a year when they are lucky and they can squeeze it in between bombings from the chicken-eating Americans.

If a chicken lives avg 6 months before we eat it, that's almost 17 billion chickens a year according to the fact Mtnrescue stated. So maybe the 200-400 billion number takes that into account.

The Audubon Society organizes bird counts every year around Christmas time all over the world.

2,054 counts were completed this year witha total of 69,354,406 world wide. You can follow this link to find counts from all over the world.
