Hi everyone, I had my first brood of bluebirds this year. It seems to me it was a little early in the year (May), but I'm new to this. I didn't count the eggs and fledglings, but they were there for about 3 weeks, then one day I looked out and saw a house sparrow go inside. I immediately went to view the nest, found 1 dead baby bb, but the rest were gone. I later saw the parents feeding the fledglings in my yard, so at least 2 survived. I cleaned out the nest & box, but a housesparrow kept going in, so I took passive measures, spooker and fishing line. The sparrow finally gave up and I had 3 bluebirds going in and out of the box. 1 male, 2 females. A new nest was built about 3 weeks ago, the male is still guarding, but no eggs. Should I remove the nest so that they start again? or just leave it be? The sparrow spooker is still up, but the BBs seem to love it as a perch and keep going in and out. Any advice will be appreciated!
