What the records say about Gaerwen
193 bird species have been recorded within 5 km of the centre of Gaerwen (Anglesey) since 2010, across 24,049 public observation records shared through GBIF. The most recorded are Mallard, Northern Lapwing and Carrion Crow.
Water shapes this list. 42% of records near Gaerwen are ducks, geese, gulls, waders, herons and other waterbirds — Mallard, Northern Lapwing and Graylag Goose lead them — which points to coast, estuary, river or open water within range. Carrion Crow is still the most logged garden bird.
15 birds of prey are on record nearby, including Eurasian Marsh-Harrier, Common Buzzard and Common Kestrel.
Records peak in May and are lowest in August — about 5.9 times as many in the busiest month. Part of that is birds (migrants and winter visitors), part is people: more birders are out in good weather, so treat the curve as activity, not a census.
