Estimating current IBWO population numbers

Excerpt from this post:
...Taking into account the state of the forest I have personally seen on public and private land, I would guess there may be as many as 20 breeding pairs in the state and maybe a total population of 50 to 75 birds in South Carolina. If the same estimate were true throughout the range of the IBWO, I would guess there might be something in the range of 250 to 750 birds extant (there might be many, many more if most of the Mississippi River bottoms had not been converted to soybean fields and catfish ponds).

Interesting.
My estimates are from 50-75 birds less than his, in the mentioned area, to 250-750 lower overall. But we're close.

I would estimate, then, that the low point of IBWO population was in the 40s and 50s,...


Yup, that sounds about right.
