For what it's worth, Shrikes did show a spike in the Lower Ninth Ward of New Orleans in the 2nd (or 3rd- memory fades) winter after Katrina, as did Red-tails and Kestrels. There was a pretty impressive density of raptors there for one winter especially, which I interpreted as response to a spike in rodents. It was not a permanent increase for the predators however.

Erik et al.-
Yes, thanks for the report and for organizing and participating in the
count. To me, the drop in shrike numbers is particularly disturbing. As
the species continues to disappear inland, the coastal zone had become
somewhat of a refugium for shrikes. Hopefully, they will come back
stronger than ever in that area.
