Hi LT, Sadly, an aggressive house sparrow (HOSP) took up residence in our bluebird nesting boxes and destroyed the eggs in the recent nest and drove the nesting pair away.
For the last 5 years, I have had great success (3 broods every season) with my non-violent HOSP deterrent methods—Sparrow Spooker and fishing filament. I am pretty devastated it didn't work this year and wonder what I should do now. One, with the nesting HOSP. And two, how to proceed for the rest of the spring to try to entice the bluebirds back to a safe nesting area. I am considering changing the boxes out to ones that are more sparrow proof. If anyone has had a similar issue and has had good success with certain boxes & preferably with deterrent methods vs. extermination, please advise. (I am interested in hearing all methods, though as I don't want to take the boxes down, nor do I want to help increase the invasive HOSP population.) Thank you, Staci
