The house hadn't merely attracted an animal.
Part of it had inadvertently become an enormous pantry.
How Could One Bird Store So Much?
At first glance, the obvious question is how a woodpecker could possibly accumulate such an enormous amount of food.
The answer lies in persistence and the unusual structure of the storage location.
The bird was reportedly collecting acorns and placing them into holes in the exterior siding.
Under more natural circumstances, food stored in a suitable cavity would remain close enough for the bird to retrieve later.
But a house isn't a tree.
Once an acorn entered certain openings, it could drop down into the hollow wall cavity instead of staying near the entrance.
That meant the storage space effectively had far more capacity than the bird may have expected.
The woodpecker could insert an acorn, watch it disappear, and then return with another.
If the nut fell out of reach, there was still room for the next one.
And because the interior cavity wasn't visible from outside, the homeowner couldn't easily see the growing pile either.
This could continue repeatedly.
Day after day, trip after trip, the bird's tiny contributions accumulated.
Eventually, the house contained hundreds of pounds of food.
The Woodpecker Had Accidentally Created an Inaccessible Pantry
There is an almost comical—and slightly unfortunate—side to the situation when viewed from the bird's perspective.
The woodpecker was doing exactly what its instincts told it to do.
It was gathering food and attempting to preserve it for later.
Each acorn required effort.
But the investigation suggested that the problem extended much farther.
The bird had to locate it, collect it, transport it back to the property, find a suitable opening, and place it inside.
But there was one major flaw in the plan.
Many of the acorns apparently weren't remaining where the woodpecker put them.
They were falling farther into the wall.
In other words, the bird was repeatedly filling a pantry that it might not have been able to empty.
From a human perspective, hundreds of pounds of acorns inside a wall is an extraordinary property problem.
From the woodpecker's perspective, it may have been hundreds or thousands of successful-looking food deliveries followed by mysteriously disappearing supplies.
The very feature that made the house such an attractive storage location—its enormous hidden cavities—also made it a terrible place to retrieve the food.
