Do you love our Ynys-hir nature reserve? Share your thoughts with the community. Or if you're thinking about visiting and would like to find out more, ask away!


  • Spring arrivals

    A wealth of sightings for you as Spring gleefully unravels it's way into the seasonal procession. We seem to be hearing more and more singing chiffchaffs on a daily basis, and the reserve has also recorded it's first wheatears and sand martins of the year. There is much to be seen still on the raptor front as well, with one of the Dyfi ospreys (Blue24) returning on the 24th, and the continued presence of hen harriers, notably a female who tarried around Marian Mawr pools on the 15th. Other bird sightings include two yellowhammers at the feeders on the 2nd. a great white egret by the Saltings trail on the 15th, and a veritable feast of interesting activity on the 28th, which included a single gargany, 3 willow warblers, a cetti's warbler at Covert Du, yellowhammer, and 2 little ringed plovers on Breakwater fields.

    A stroll along the boardwalk on warmer days may provide encounters with the caterpillars of Drinker and Oak eggar moths, both of which I have seen on Covert Coch in the past few weeks. These species hibernate in the larval stage over the winter before emerging to recommence feeding in the Spring, and have a wide range of food plants (including heather, bramble, blackthorn, and bilberry for Oak eggars, and a variety of grass species for Drinkers). For those wanting to see adult lepidoptera, brimstone are being observed on the reserve with increasing regularity, as well as the odd red admiral. Following on from last blog's lesser celandine, wood anemone is another early spring bloomer, preferring dry woodlands of deciduous trees, and the first are just starting to come into flower in Coed Penrhynmawr. Hopefully a prelude to a burst of their white flowers in the next few weeks.

    Finally, another fungal feature. This week, the scarlet elf cup, which grows on branches rotting on the ground, apparently most often from lime and maple, though the specimen below was under an oak.

    Spring is well and truly underway!

  • Storm Doris and the approaching Spring

    Ynys-hir has had it's fair share of the recent gull activity in the county, with a 1st winter glaucous gull on the 26th, as well as first winter and adult little gulls on the 23rd, which associated with the black headed gulls and fed on the river whilst avoiding the worst of Storm Doris. In Europe, little gulls typically breed on freshwater marshes in the Baltic states and Scandinavia, wintering in coastal areas along the Mediterranean and western Europe, but a pair at RSPB Loch of Strathbeg in 2016 became the first record of a successful breeding attempt in Britain, raising two chicks. Also on the afternoon of the 23rd three bewick swans took refuge from Doris on the saltmarsh, but stayed only briefly. A single hen harrier on the 12th, and two on the 28th over Rushy Field complete the sightings of interest. 

    Distracting us from the stormy weather,the burst of spring and summer flowers that we are all looking forward to at the reserve is being foreshadowed by the yellow splashes of lesser celandine, which is just coming into flower. A member of the buttercup family, lesser celandine is commonly found in woodlands and hedgerows in damp soils, and is an excellent nectar source for early emerging insects. Wordsworth was a fan, writing not one but three poems about them (evidently he preferred them to daffodils), describing the timing of their blooming as 'soon as gentle breezes bring news of winter's vanishing'. Warmer weather to come then!
