From today, children in Wales will be taking part in the world's biggest school wildlife survey.
The survey helps to track bird numbers and gives an insight into populations, with the results contributing to the RSPB's Big Garden Birdwatch - the world's biggest wildlife survey.
Last year, over 4,500 pupils and teachers across Wales counted the birds in their school grounds, discovering the Blackbird to be the most commonly seen.
It was followed by the Starling in second place, and the Black Headed Gull in third.
The RSPB's Big Schools' Birdwatch forms part of this year's Big Garden Birdwatch - the world's biggest wildlife survey.
As the RSPB's birdwatch survey gets underway, here's a guide to how you can spot some of the most common garden birds.
