I'm not ready to concede that Rick. Zero potential is seeing hay fields rep=
laced with corn or soya fields or built on and paved over, both of which I'=
ve seen plenty of.

It all depends on how early the first cut was. If it was early enough the h=
ay may have grown sufficiently for Bobolinks to establish territories and n=
est. If this is the case it is the timing of the second cut that will deter=
mine if any Bobolinks succeed.

Regarding the later dates for Bobolink nesting that you mention, there is n=
o question that some Bobolinks will probably still be nesting when a cut is=
 made. However, the July date I mentioned in my earlier email was chosen to=
 allow the farmer to get usable hay from his cut and still allow a large ma=
jority of nests to have fledged their young. If he will only accept the max=
imum protein content in his hay and he cannot compromise then there will be=
 a problem.

All the best,

Lance
