Thanks for the detailed information on using fishing line on blue bird
houses.  I have a pile of house sparrows around this year (bumper crop,
like white-footed mice on acorns?) and would like to add hole-guards to the
houses.  Directions call for entries less than an inch in diameter.  Can
blue birds really enter through holes 3/4 inches?  Anyone following the
directions may have an answer.  Thanks  Robley Evans  North Stonington

P.S.  Pair of yellow-bellied sapsuckers passed through on Friday.
