A company based in Solva has developed new mobile phone technology to record the animal's position.
The app is free and can be used in remote areas without wi-fi.
Its inventor told Abigail Neal how mapping these sightings could help protect the birds.

Aisha told Time her nose and ears had been cut off - with the approval of a Taliban commander - by her abusive husband as punishment for running away.
The front cover generated debate over the headline "What Happens if We Leave Afghanistan" and over the use of the photo itself.
Her surgery was done in California.
The Grossman Burn Foundation, which carried out the work, campaigns on the issue of violence against women, as well as doing free plastic surgery work.
Foundation surgeon Peter Grossman carried out the reconstruction surgery.
Aisha was widely photographed and filmed earlier this week receiving the Enduring Heart award at a benefit ceremony staged by the foundation.
She was given the award by California first lady Maria Shriver, the wife of California Governor Arnold Schwarzenegger.
"This is the first Enduring Heart award given to a woman whose heart endures and who shows us all what it means to have love and to be the enduring heart," Ms Shriver said.
Aisha - whose surname has not been revealed - replied: "Thank you so much."
The 18-year-old was reportedly given away by her family in childhood as a "blood debt" and was subsequently married to a Taliban fighter.
His family abused her and she ran away but was recaptured and mutilated by her husband.
Aisha's case has been used in the West to illustrate the fear of what will happen if US, British and other international forces leave prematurely.
Some critics questioned the tone of the Time cover arguing that it was using emotional blackmail and gender politics to justify continued US involvement in Afghanistan.
Technology pioneered in Pembrokeshire is being used to track endangered birds of prey in Africa.
