[CT Birds] Shrike Question

[paul cianfaglione]

This question may be best directed to long standing members of the birding community or to people familiar with RBA's in other states.  I have had 7 Northern Shrikes in the Hartford area this winter and was wondering if this year was going to be considered an "invasion year" for the species. I have never experienced a shrike invasion before, but this winter there seems to be a shrike in every farm field I visit. With all the focus being directed toward finches, I thought that maybe shrikes and their overall numbers maybe flying under the radar this winter.
