There are two categories of species: r & k.
The former, which includes rodents and insects, are highly adaptable. They have relatively short life-spans, short gestation periods, and produce lots of offspring very quickly. Insects are particularly adaptable, and can produce sub-species to cope with major environmental change in just a few generations. When the meteor that wiped out the dinosaurs hit Earth, lice would have had no long term worries.
The dinosaurs, however, being k species stood no chance. k species evolve strictly to cope with their environment. Population levels are always at or very close to carrying capacity. Environmental change poses a major threat to them. They reproduce relatively late in life, have long gestation periods, and have few offspring. They simply have not evolved to cope with environmental change.
Birds are k species. Perhaps this explains what happened to the dawn chorus.
We are also k species by the way. Think about it......
