The Irish Garden Bird Survey runs from the first week of December to the last week of February every winter, which amounts to 13 weeks. For winter 2021, the survey begins in the week of Monday 29th November.
It’s not necessary to carry out the survey in every single week, as people are often away from home over Christmas etc., but if you can complete at least 10 of the 13 weeks then you’ll still be providing us with a high level of bird data.
