Good news, bad news

Great press release from Butterfly Conservation, courtesy of my old friend Liam Creedon, editor of Butterfly magazine, follows - and a fine pic of a Small Tortoiseshell (above) on barley, from Tim Melling:


Farmland butterflies thrived last year after benefiting from the best summer weather for seven years, a survey has revealed.
Typical farmland species such as the Brimstone, Common Blue, Small Copper, Small Skipper, Large Skipper and Small Tortoiseshell all bounced back in 2013 after experiencing a crash in numbers during 2012.
The Wider Countryside Butterfly Survey (WCBS), which assesses the fortunes of common and widespread species, found that many farmland butterflies flourished as a result of long periods of warm, sunny weather last summer.
The annual survey, running since 2009, counts butterflies in more than 850 randomly selected 1km-squares across England, Wales, Scotland and Northern Ireland to assess the health of butterfly populations across the wider countryside rather than at specially managed hotspots such as nature reserves.
Hedgerows and field margins that are characteristic of farmland are an important habitat for butterflies. Overall, the majority of farmland species recovered in 2013 after suffering one of the worst years on record for butterflies in 2012.
Last year recorders saw an average of 85 butterflies of five species per survey made over July and August - almost double the numbers recorded in 2012.
The Small Tortoiseshell, which has suffered an ongoing decline, recorded its best summer since the start of WCBS. More than 6,833 individuals were counted with the butterfly seen in 80% of squares compared to just 40% in 2012.
Following an appalling 2012, the Common Blue also enjoyed a good year with an average five-fold increase in abundance per-square. The Small Copper and Brimstone also thrived - and were both more widespread and abundant than in the previous year.
The Large White and Small White, commonly known as the 'cabbage whites' were also recorded in profusion with more than twice the number of Large Whites counted per square and five times the number of Small Whites in 2013 than in 2012.
For the fifth year in succession the Meadow Brown was the most widespread and abundant species. The butterfly was recorded in more than 90% of squares with 8,000 more butterflies counted in 2013 than 2012.
The Holly Blue and Red Admiral were among the minority of species that didn't have such a good year with numbers down for both compared to 2012.
WCBS Co-ordinator Dr Zoƫ Randle from Butterfly Conservation, said: "Farmland butterflies really thrived last year primarily due to the fantastic summer weather which provided ideal conditions with several recording their best ever WCBS results.
Kate Risely, who co-ordinates the Breeding Bird Survey butterfly surveyors at the BTO, said: "It's great news that populations of widespread butterfly species increased in 2013.
"These results demonstrate the value of large-scale volunteer surveys for monitoring country-wide trends in butterfly numbers. Recording butterflies and birds at the same sites gives us a unique insight into the health of our countryside."
The WCBS is run by Butterfly Conservation, the British Trust for Ornithology (BTO) and The Centre for Ecology & Hydrology (CEH) as part of the United Kingdom Butterfly Monitoring scheme (UKBMS).

Just the thing for a sunny day in February, full of hope for spring (try not to look at tomorrow's weather forecast).
The good year on farmland certainly seemed to be reflected on the dunes, with big numbers of species like Grayling and perhaps most notably Walls, last season.
On the down side, I've just started reading the excellent, if sobering, "The Sixth Extinction" by Elizabeth Kolbert, reminding us that things are far from rosy in the global garden.
Not got much birding done the last few days (busy, busy), but had a Raven over the dunes at Freshfield yesterday and a male Blackcap is still coming to fatballs at Dempsey Towers.
Eyes to the skies everyone, eyes to the skies...


Male Stonechat singing in the dunes at Ainsdale today, with a female coming in to join him.

Unexpected sighting this afternoon - an adult Little Gull over Queen's Jubilee Nature Trail at about 1.30pm.
