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.

During 2025, volunteer bird ringers for the British Trust for Ornithology monitored 29 songbird species at specified locations under a project known as the constant effort sites scheme.
