UGG!! I have to stop trying to interfere with mother nature. I should already know this, but sometimes I try to help. I do provide food and shelter, but other than that I have to stop. Animals and birds do what they want, just as some people do what they want. Someone once told me that if they wanted to, they would. That applies to all living things.
It started this Spring. A pair of Eastern Bluebirds began looking for a home to nest in. For years I had bluebirds. I loved them and looked forward to two broods per year. I would watch them make the nest, lay eggs one per day and then wait for the babies. It is always so much fun when the fledglings leave the nest. Then one year the House Wrens showed up. As I have mentioned in other blogs, I would see them fly into the bluebird house and pierce the eggs. They would then throw them on the ground and dismantle the nest. I was so upset. I did discover a wren guard and if the bluebird got to the point of actually laying eggs, the wren guard would protect them. The last two years the bluebirds would show up but eventually get discouraged by the House Wrens. They couldn't get their nest and eggs in place in time.
I thought this year would be different. In early spring the bluebirds arrived as scheduled. The House Wrens hadn't arrived yet. The bluebirds couldn't decide on a house. By the time they did, the wrens arrived and I believe the bluebirds eventually nested elsewhere.
Fast forward to the first week in June. Wrens are known for building their nests of sticks in every single birdhouse they can find. All of them are mock nests except for one. This discourages all other birds from nesting in the same area. In one of the nests, the female lays her eggs.
Things had calmed down here and the wren was quiet. I assumed they were nesting somewhere but I didn't know where. There were two birdhouses that were empty except for one. That one didn't have any eggs, just a house full of sticks. I didn't know if I should remove the sticks so they would be busy bringing in more or if they thought the full mock nest was complete and they would leave it alone. I just didn't want them to lay eggs in that house. I concluded that I should just leave well enough alone.
During this quiet time, the bluebirds returned. They began building a nest in one of the empty houses and all was well. I thought maybe they found a good time to build a nest.
Things were going great. The House Wren wasn't paying attention or so I thought. When the nest was complete it was a work of art. I took a peek to see if there was an egg yet. There wasn't.
Then I waited. The bluebird pair would come to check on things, but suddenly the wren showed up. She/He started to pull the bluebird nest apart. The male bluebird kept trying to chase him off but the wren was relentless.
I have a wren guard that I usually put up after the first egg is laid. There is a learning curve for the bluebirds to enter the house with the guard on. A mothers love makes it possible to get to the egg. I didn't know if they could learn before the eggs were laid, but I had no choice. I put up the guard. The bluebird and the wren were confused. It served the purpose, the wren couldn't figure out what to do but the bluebird couldn't figure it out either.
I thought I would wait but this morning I noticed the bluebirds building a nest in another location. I had put my hummingbird camera in this location and hadn't taken down this old house yet. They worked really hard all morning building a new nest. It was a quick process. Nest building usually takes several days.
The second nest is now complete, but the male bluebird is flying back and forth between the two houses. I guess he forgot which is home. We will see which nest they choose. I should say which nest SHE chooses. I have a feeling I know who's the boss. He helps choose the nesting site but she builds the nest, lays the eggs and sits there for hours after the last egg is laid except for a break once in a while. The eggs hatch in a couple weeks and then both parents participate in feeding the young ones.
I waited to post this in case the egg laying process has begun. It has not. The bluebirds are very smart or at odds. I'm not sure. He has spent the day sitting on top of the house with the first nest. She has spent the day going in and out of the second nest and the wren is sitting on his house of sticks not quite sure who to taunt. I will amend this blog when I know more.
UPDATE! June 15, 2025. Here is the update I promised for this blog post. The wren is still hollering and thinks he is in charge of the 1st bluebird nest. Meanwhile Lady Bluebird had laid 2 eggs with a couple more to come before she starts incubating them. Keep your fingers crossed. So far, so good.
