bz, I personally would trade a dozen pair of wood ducks for a pair of hooded mergansers. Maybe locally hooded mergansers are common for you but nation wide, they sure aren't. We're raising thousands, if not hundreds of thousands of wood ducks. That's sure not true for hooded mergansers.
Double-Camp, with the exception of cormorants, the huge advantage of migratory birds is that they move on quickly. What that means is that we only have to scare them away a couple of times and they move on.
