What the records say about Cwm
138 bird species have been recorded within 5 km of the centre of Cwm (Blaenau Gwent) since 2010, across 25,112 public observation records shared through GBIF. The most recorded are Blue Tit, Great Tit and Blackbird.
Cwm is a garden-bird place: 79% of the records here are small songbirds, doves, woodpeckers and the other birds that come to feeders and garden trees. Blue Tit, Great Tit, Blackbird and Robin make up the core of what you can expect at a feeder.
18 birds of prey are on record nearby, including Common Buzzard, Red Kite and Tawny Owl. 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 7.4 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.
Abertillery, 3 km to the east, has a similar number of species on record (139 against 138). Birds logged far more often around Cwm than there include Tawny Owl, Barn Owl, Eurasian Curlew and Little Owl.
At about 219 m above sea level, Cwm sits higher than most places in Blaenau Gwent. 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 41 min at midsummer to 7 h 47 min at midwinter here. Sunrise is about 6:18 in mid-April and 4:53 in late June; the dawn chorus starts 30–60 minutes earlier.
