As we continued to play whack-a-mole with start-up glitches, we remained optimistic we were close to having worked through every apartment: mini-splits condensing, dryer vents not secured sufficiently, fobs for easy access not working (someone pulled the plug and the batter ran out), loose tiles, overhead lights needing tightening, community garden having less than perfect soil preparation. Then the pigeons arrived.
When the house was vacant for months, pigeons roosted and nobody paid much attention. We were now. Their gentle cooing transformed into an "I dare you" to figure out how to make us leave. We hired pigeon whispers to add spikes all around the house. The pigeons moved to the porch overhang. Eventually Jeff screened off the overhangs - double sided after he pressure washed the steps and entry.
They moved to a small overhang above Hawthorne. At least they waited until Jeff had painted the front steps.
