With the imminent heat wave known as the UK, it’s not just the warm weather that humans are expecting.

As migratory birds arrive from a distance and the butterflies stretch their wings, it is expected that the warm spell will temporarily lift nature.

The British Trust in Ornithology (BTO) says a series of mild winters and wet springs are contributing to the changes in the natural world.

While the brief warming spell doesn’t have much impact on the natural world as a whole, it may be a benefit for nature lovers.

"On the plus side, better weather is more tempting, let's go out and enjoy the spring. The Dawn Choir is perfect for enjoying it at the top of a minute, calm, warm mornings."

The Metropolitan Office said that a short-lived warm spell is not a bad thing for wildlife - it has little impact on water sources such as ponds.

"Climate change has had a big impact on our wildlife, but temporary debris like this is the dividend of wildlife in April," said Grahame Madge of the Metropolitan Office.

Some wildlife accelerates their activity in warm spring weather, so people may see the natural areas near them consistent with life this week.

Mr Madge added that butterflies and birds may be particularly prominent.

Some studies have shown that warm weather means birds can breed earlier this year and do not need to hatch their young as long as possible.

Migratory birds (such as swallows and swift) return to the UK as more insects can feed in the warm gas and may return faster. The Metropolitan Office said there were swallows in southern England before March this year.

Butterflies can also be seen in warm weather. The days a year ago were hotter and could bring the Red Admiral, formerly a migratory insect.

Peacock and turtle shells were one of the first to spread their wings, and since April, more butterflies have appeared.

Dragonflies have also begun to be seen during this period.

It is also possible to see some rare tourists, such as the exotic European bees, who have recently begun to nest in the UK.

Wildlife charity says it's a good time to go out and enjoy nature, but people should accidentally get angry.

Oliver Fry of the Surrey Wildlife Trust said the conditions in the Heathlands in Surrey were very dry and Surrey produced “Tinderbox conditions.”

Wild, flat landscapes are dotted with Gorse and Heather, known for their wildlife, including rare species such as sand lizards, Woodlark and silver-shaped blue butterflies.

Earlier this month, conservationists warned that some of the rarest wildlife in the UK were “alive” and were getting closer to extinction after weeks of intense grass fire.

RSPB Scotland Director Anne McCall said climate change is driving stronger conventional wildfires, especially in the spring.

“It’s not just vegetation destroyed by wildfires,” she said. “It’s a critical moment of the year for our native wildlife – birds nest and other animals, such as amphibians and reptiles, start from dormant in winter and start breeding.”

On the coast, conservation experts say there are already a large number of witnesses of whales and dolphins approaching the British coast - while it is difficult to determine a reason, warming oceans and climate change are likely to be a factor.

“It’s always a great experience to see whales and dolphins in the wild, but seeing more experiences, more unusual species around the British coast may not be a good thing,” said Danny Groves of the charity Whale and Dolphin Conservation.

He added that heat waves and elevated SST may cause some whales to roam away from their usual areas to survive.
