What the records say about Deiniolen
132 bird species have been recorded within 5 km of the centre of Deiniolen (Gwynedd) since 2010, across 6,668 public observation records shared through GBIF. The most recorded are European Herring Gull, Jackdaw and Blackbird.
Deiniolen is a garden-bird place: 76% of the records here are small songbirds, doves, woodpeckers and the other birds that come to feeders and garden trees. Jackdaw, Blackbird, Robin and Blue Tit make up the core of what you can expect at a feeder.
11 birds of prey are on record nearby, including Common Buzzard and Eurasian Sparrowhawk. A hawk that hunts feeder birds is among them, so set feeders 2–3 metres from shrubs: close enough for cover, far enough that a cat can't ambush from it.
Records peak in May and are lowest in October — about 5.2 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.
Llanberis, 3 km to the south, has fewer species on record (122 against 132). Birds logged far more often around Deiniolen than there include Common Whitethroat.
At about 212 m above sea level, Deiniolen sits higher than most places in Gwynedd. Spring arrives a little later with height, and feeders matter more in cold snaps — keep a supply of high-fat food going through late winter.
Daylight runs from 16 h 58 min at midsummer to 7 h 32 min at midwinter here. Sunrise is about 6:19 in mid-April and 4:48 in late June; the dawn chorus starts 30–60 minutes earlier.
