TRES vs Chickadee...who will win??

17 years ago

Ok, last week Wednesday I put a 1 1/8 inch reducer on one of the houses that some TRES were hanging around but hadn't started building a nest in yet. We have 6 other pairs of TRES with almost completed nests at this point and I am thinking eggs will be laid any day now since they have been doing the swishy swishy. I did see a pair of chickadees checking out the box with the 1 1/8 inch reducer last week and noticed them hanging around after that too however this pair of TRES will not go away from this box. I really don't think they can get into it, they hang on the front and seem to try to get in but never go in but they won't go away. Yesterday afternoon I thought they left and this morning I was happy to see the chickadees going in and out, they seemed like they may have started nestbuilding as they would fly into the woods and come back go in and be in it for a bit, fly back out and repeat. One would stand guard while the other was in the house however I couldn't see anything in their beaks but I am watching with binocs as I am quite aways away. Well once when on of the chickadees was in the house the dang TRES came back and they seemed quite upset that the chickadee was in the box. The one Dee standing guard tried to chase the TRES away but they wouldn't leave. The one in the box stayed in there for a good five minutes. I was trying to figure out if it was scared or just standing its ground as it had plenty of opportunities to get out of the box but it didn't. The one TRES would flutter around the hole for a bit and then fly to a tree or the top of the box. The other chickadee was just staying around but not trying to chase the TRES away anymore. Why would the pair of TRES stay around if they cannot get into the box, I don't get it. Do you think the Dees will be scared off by the TRES? I did put another portable house up with a 1 1/8 hole just to try to keep the Dees here if the TRES do scare them from this box but I would rather they nest in the one they are trying to. Anyone ever have a problem like this before, who won?

Oh and I am happy to say down at the park near our house where I monitor five nestboxes we FINALLY have one pair of Blues with what looks like a completed nest. I am thinking we should have eggs soon, am planning on checking it again tonight.
