Skomer Wardens Ed Stubbings and Bee Büche visited Newgale beach in Pembrokeshire on February 23.
“We found around sixty dead seabirds, almost half were razorbills” said Ed.
“Like wrecks of birds recorded elsewhere on the coast, many were clearly malnourished, and had suffered badly in the stormy conditions”.
"If anyone finds dead birds on the beach please look for metal rings and report the numbers to the British Trust for Ornithology (BTO)".
The Wildlife Trust of South and West Wales says one of the stormiest winters on record is seeing dead birds washing ashore on many of our beaches.
The Trust, which manages the internationally important seabird islands of Skomer and Skokholm on the Pembrokeshire coast, says deaths are being reported on beaches like Newgale, Broad Haven and Ferryside
It says between them Skomer and Skokholm are home to over 20,000 puffins as well as around 28,000 guillemots and 9,000 razorbills,
A leading Welsh tourism operator has criticised the Met Office for scaring away visitors with their warning of a severe storm. Wales escaped the worst of the threatened damage with the bad weather hitting the south West England instead.
As the downpour hit Wales - hundreds of students ignored the storm to go on a Cardiff pub crawl and dance in the rain.
University freshers paid little attention to to the severe weather warnings and went out drinking across the city centre in fancy dress as part of a series of Carnage events.
And torrential rains and winds in excess of 90mph on Sunday night did nothing to damped their spirits as they took to the streets in short skirts and cropped tops.
The students wore white Carnage T-shirts - and there wasn't a raincoat or umbrella in sight.
Council workers were out in the city this morning clearing roads after heavy rainfall last night.
Although Wales avoided the worst of the storm, 6 flood alerts remain in force across the country.
One vehicle became stuck in deep water on Penarth Road in Cardiff and the road remains closed as workers attempt to clear the area.
Local bus services are diverted.
The M4 Second Severn Crossing has now reopened after being closed overnight due to high winds.
