What the records say about Cemaes Bay

217 bird species have been recorded within 5 km of the centre of Cemaes Bay (Anglesey) since 2010, across 24,318 public observation records shared through GBIF. The most recorded are Eurasian Oystercatcher, Sandwich Tern and Black-headed Gull.

Water shapes this list. 63% of records near Cemaes Bay are ducks, geese, gulls, waders, herons and other waterbirds — Eurasian Oystercatcher, Sandwich Tern and Black-headed Gull lead them — which points to coast, estuary, river or open water within range. Carrion Crow is still the most logged garden bird.

14 birds of prey are on record nearby, including Common Buzzard and Common Kestrel.

Records peak in May and are lowest in December — about 23.5 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.

Amlwch, 7 km to the east, has fewer species on record (157 against 217). Birds logged far more often around Cemaes Bay than there include Mallard, Little Egret, Arctic Tern and Common Tern.

Daylight runs from 17 h 1 min at midsummer to 7 h 29 min at midwinter here. Sunrise is about 6:20 in mid-April and 4:48 in late June; the dawn chorus starts 30–60 minutes earlier.
