Dr Phil Smith: Wildlife Notes November 2021

Portuguese man o war Ainsdale by John Dempsey

November is generally a quiet time for wildlife. However, Ian Wolfenden reported a huge movement of winter thrushes at Hightown on 4th. He estimated an extraordinary number of 5000 Fieldfares and 2000 Redwings flying north. Strong winds from the southwest on 6-7th brought in an unusual bounty from the tropics, John Dempsey finding a colourful Portuguese-Man-of-War and several By-the-wind-sailors on Ainsdale beach.

Dr Phil Smith: Wildlife notes October 2021

October had a total of 16 rain-days, being wet and windy early and late in the month, with a dry 10-day period in the middle. Gales in early October blew in masses of sand, deeply burying the rich strandline vegetation at Ainsdale that I highlighted in the September notes. The associated 10m high-tides washed up drifts of seaweed, presumably from North Wales, which will provide the nutrients for next summer’s strandline plants.

As in October last year, the relatively warm weather kept insects going longer than usual.

Broad-leaved Helleborine Epipactis helleborine Ainsdale NNR 1 08 21.jpg

My month with nature started well when Joyce and David Jarvis showed me two flowering Broad-leaved Helleborines at Ainsdale National Nature Reserve. I hadn’t seen this orchid on the Sefton Coast since 2008.  Other notable plants during the month included a small colony of Whorl-grass that I found on a freshwater seepage zone on Hightown beach. It turned out to be the rare variety uniflora, largely confined to Western Scotland with only two known localities in England. While listing the associated species, I came across a plant that I couldn’t name but which seems to be Touch-me-not Balsam (Impatiens noli-tangere), not previously recorded for the Sefton Coast.

Extreme heatwaves and prolonged spring and summer droughts are a predicted consequence of climate change. Fortunately, most of our sand-dune specialist flora and fauna seem able to cope at present, being adapted to life in harsh conditions.

 A loud hum preceded the arrival of two enormous, tropical-looking insects that crashed into the grass a few yards away; each was over an inch long and their identity had me foxed until my photographs confirmed a mating pair of the Birch Sawfly. I've never seen one before and I was able to trace only a single previous Sefton record of a really impressive creature.

Narcissus Bulbfly Merodon equestris pair Hawksworth Drive

May 2021 was one of the wettest on record. Some parts of the country had more than twice their normal rainfall. Most insects like it warm, so May’s cool conditions should have meant fewer of them. This was not at all the case. Spring species are well-adapted to the cold and if it’s cool they spend more time basking in the sun to warm up, making them easier to find.

Dr Phil Smith: Wildlife notes March 2021

​  Large Bear-hoverfly (Criorhina ranunculi) Ainsdale NNR  ​

March was a relatively dry, settled month with measurable rain on only 10 days. However, wetter conditions from 9th to 16th raised the water-table at the Devil’s Hole to the highest level since I started measuring it in October 2015. The usual spring high pressure became established towards the end of the month, the warmest ever March temperature of 24.5 degrees being recorded in London on 30th. In Formby, it peaked at more reasonable 20 degrees. These spring heat-waves are becoming more frequent, as a predicted consequence of climate change.
