Musta been a very freak wind or determined giraffe to take off the dryer vent cover.
Bird didn’t care how it was removed, finding it a handy safe place for a nest. Filled the vent so completely that the dryer was taking twice as long a normal to dry a load of clothes.
Nest removed…no, the birds were not in residence and no eggs or babies were harmed.
But the dryer worked a lot better with a new vent cover and we added a giraffe monitor for good measure.
