The swifts are in freefall since the introduction of neonicotinoids

It is the most miraculous bird, the ultimate winged messenger, exploring our globe, spending its life on the breeze. Sickle-shaped wings silhouetted against the sky, the swift (Apus apus) is the fastest of all birds in level flight and remains entirely airborne for 10 months, or more, feeding, sleeping and mating on the wing. These long-lived creatures can clock up 4 million miles, commuting between English summers and African winters.

But this bird is in freefall. A graph produced by the British Trust for Ornithology is terrifying: the British population declined by 51% between 1995 and 2015. And the rate of decline is increasing: down 24% in the five years to 2015. We are belatedly waking up to the global calamity that is the loss of insect life. The German study showing a 76% decline in flying insects since 1989 is no anomaly. In Britain, for instance, three-quarters of butterfly species have declined over 40 years, while moth abundance has fallen by more than 40% in the southern half of the country.
