Robin and blackbird numbers in the UK plummeted in 2019, as the hot summer dried out the earth and made it harder for the birds to find insects and worms to eat.

In contrast, species like **** — which eat insects living in trees — thrived, data collected by British Trust for Ornithology volunteers revealed.

The results also revealed that 2019 had an early breeding season — possibly due to the record-breaking February temperatures.

In warmer springs, birds are known to lay their eggs earlier so that their young hatch when the insects on which they feed are at their most abundant.

The most successful birds last year appear to have been the **** — with numbers of blue, great and long-tailed **** starting and ending the breeding season strong.

The good start to the year followed an excellent breeding season in 2018 — and many of the **** encountered by the trust's bird ringers last year were noted to have been juveniles that were nesting for the very first time.

Volunteers - Nests - Breeding - Pair - Number

Volunteers monitoring nests also found that each breeding pair also produced a higher-than-average number of chicks — a finding that could potentially herald a similarly successful 2020 for the ****.

Much may depend on the weather this winter — while such has been relatively mild to date, the recent wet conditions can be challenging, especially for younger and less experienced birds.

In contrast, several common species of birds seen in British gardens endured a particularly challenging 2019.

The numbers of both blackbirds and dunnocks counted sank to their lowest since the trust's practice of ringing began in 1983.
