This year, counts have been submitted for a total of 549 sites totalling 2053 nests.
Each marker represents a site with at least one nest - click or tap on the marker to see more details. Some sites are indiviual houses, shops or other buildings; some are roads or villages with several nests on different buildings. At many sites, we think that only a small proportion of nests were reported and that the colony had several additional pairs nesting nearby.
Help us fill in the gaps on the 2026 map by telling us where you have seen nests in use on this page.
