Interesting place to build a nest

[kwired]

Not exactly sure, but in the top pic from David, it appears that there are 3 cutouts underneath the nest. Not like an explusion fuse cutout, just a switch type. And they sure look like they are hanging down.

So maybe one side of those 3 lines is isolated?

And those birds are smarter than we give them credit for

I wouldn't bet on it, likely they can close them to reroute the direction of feed depending on what they might be working on, otherwise they likely open nearly all the time and normally live on both sides and of course the two sides are in phase with one another so they can close them then go open whatever other switch they are bypassing without interrupting service to customers in the process.

At least that seems to be commonly the way it is done here. Rural POCO can shut down a substation to do some major work (usually during a time of year when peak loading isn't very high) and can operate some these switches so that power gets rerouted from the way it normally gets routed during the project.
