Thousands of birds were captured flocking along the coast in a "Spectacular" aerial show. 

Gra Bloomfield snapped the natural wonder at RSPB Snettisham on Wednesday where the phenomenon can be seen during daylight hours in the off-seasons. 

It happens when birds such as red knots and avocets take to the sky to escape the incoming "spring tides" - a sudden high tide in late autumn or early spring.

Mr Bloomfield said: "The red knot will soon be returning to their breeding grounds but there is still plenty to see though as we enter the breeding season for lapwing, avocets, oystercatcher, ringed plover and others which are relatively new to breeding in this country such as the spoonbill and egret.

"I am now looking forward to the swallows and warblers returning from their holidays abroad, and of course the sound of the cuckoo that for me signals the proper start of summer."

The 'Snettisham Spectacular' was recently included in The Times' ranking of the 42 best spots in the UK to visit outside of the peak holiday season.

The RSPB website recommends arriving as early as 6.15am to be in with a chance of catching it.
