[TN-Bird] Re: pif landbird population estimate for loggerhead shrike in tn

I have not seen a shrike in Lewis County in my 5 years here.  I have  
not cruised every road and every set of power lines in this small  
county, but I would still be surprised if the total population was  
more than 10 birds; I suspect it is probably zero.  A Statewide  
population of 29,000 birds is an average of one pair per  7.5 km2.   
At this density I'd expect to encounter a pair roughly every 50-100  
hrs afield; probably more often, actually, since shrikes are more  
conspicuous than most species.  They certainly don't seem that  
numerous in Middle Tennessee; are there still shrike strongholds in  
west Tennessee?
