Starling Nest in Machinery

To you or me this might look like the vent pipe on an excavator. To a cavity-nesting bird like a starling, it looks like a perfect nesting spot. Finding a starling nest in machinery isn’t uncommon on construction sites. Fortunately, this was spotted before any nesting activity progressed too far, but as you can see, the pair had been busy starting to fill the engine compartment with dried grass and other nesting material.
