I leave the house by the back door to walk up to the village shop to buy a couple of items to complete our picnic. The patio slabs are strewn with rotting food. Slices of greying white bread turned to mush, slimy pepper, faded to a pale green. Lettuce, tomatoes, onions, all slime and mush. These are the offerings of the previous occupants of the house, thrown directly into the small brown food waste bin and not yet put out for refuse collection. The compostable bag of food waste we have placed in the bin is on the ground too, ripped open, its contents still inside. The ground is a mess.

‘Come look at this,’ I call back into the house to Mammy. We suspect a fox, maybe a badger. A rat perhaps?

‘Buy me rubber gloves,’ Mammy says as I leave for the shop. I walk out the back gate. My eyes are drawn upwards by the noise overhead. Two jackdaws are sitting on the electricity line running behind the row of houses, in loud conversation. ‘Was it you?’ I ask, looking up at them. One of them flies off, ignoring my question.

Twenty minutes later, rubber gloved, Mammy clears up the mess, returns it all to the food bin, and places a large flat stone on top of the closed lid. Secure.

Later, on the path that runs along the back of the beach, a jackdaw flies past at my eye level. It has something in its mouth. I watch it go, see it drop whatever was in its mouth. The bird circles back, lands, picks up what it’s dropped, flies again, drops it again. Repeats. And repeats. This is no accident. It knows exactly what it’s doing, dropping the object on the thin strip of stony path in between the sandy beach on one side and the grass-covered sand dune on the other. With each drop, the object cracks a little more. It’s a mussel. The jackdaw is on top of it now, holding the cracked shell firm with one foot while it pulls out the tasty flesh with its beak. As we walk along the path, I see it is strewn with cracked and crushed mussel shells. Previous meals. Smart jackdaw.

Still, it’s hard to believe that the two jackdaws near the house were the culprits of the knocked over bin. Dropping a mussel shell is one thing. Knocking over a bin is quite another. Maybe I’m accusing them in the wrong. Maybe they were simply taking advantage of another animal’s handiwork.

The next morning, Mammy is first out the door. She can’t believe it. It’s a mess again. The bin lying on its side, the stale bread, slimy vegetables and our compost bag pouring out. The large flat stone she has placed on top has, somehow, been knocked off. And in the middle of it all? The two jackdaws. They fly away when they see her, hurling abuse at her in their language, not at all happy that she has disturbed their hard work. Clever birds.

She’s put two rocks on top of the bin now. Let’s see if they can figure that out.
