Silent spring in our village.
This morning, I woke up early. One blackbird was singing in our neighbourhood. When it stopped (to find something to eat, I guess), it became silent.

In the 1990s, dozens of songbirds would've been singing, sometimes making so much noise that it was hard to sleep.

We live in a village near Utrecht with lots of (small) gardens and fields and parks around it.

The decline happened gradually, over the years. I don't think there's a single cause, like DDT in Rachel Carson's time. But it's part of a big biodiversity crisis here in the Netherlands.

As with climate, society as a whole has amnesia for this kind of thing. When you're young, or you moved into the area a few years ago, it's hard to know how many birds were singing, and butterflies and bees were flying around here, a few decades ago.
Oh, and the situation in the field next to our neigbourhood is not good either:

@Sustainable2050 it becomes especially clear when you spend a few days in another country, where there are still swallows and sparrows, insects buzz around your head, and the dawn choir is still deafening.
