My general impression this spring has been that there are fewer House 
Wrens at McKee-Beshers WMA (Montgomery Co) than usual.  My only numerical 
data is last year my high count was 11 for the first two weeks in May and 
this year it is 7 although I am doing a lot more field work this year.  Once 
I take my breeding surveys I'll have a better answer.
        I suspect that House Wrens suffered higher than normal mortality in 
the southern US because of the harsh winter similar to what happened after 
the brutal winter of 1976-77.
