UK’s warmest spring on record led to rise in songbirds breeding, data shows

Dry and warm 2025 spring gave glimmer of hope for threatened wild birds but many remain in long-term decline

The warmest and sunniest spring on record this year led to an increase in the breeding of some of Britain's best-loved songbirds, data has shown.

Scientists said the dry and warm spring had provided a glimmer of hope for threatened wild birds. In the 2025 breeding season, from May to August, there were higher than average breeding successes for 14 species including the chiffchaff, garden warbler, whitethroat, coal tit, blue tit, great tit and robin.
