After what we feared may be the first of the autumn gales over the weekend, the sun has returned and shone nicely all week. As the sun gets lower in the sky, the light reaching us takes a redder hue. This compliments the autumn colours wonderfully; with the nice weather set to continue over the weekend, the reserve couldn’t look nicer for an autumnal woodland walk.
The rowan trees provide flashes of red amongst the yellowing birches. On the ground, the tormentil has turned crimson.
The clear skies see the temperature drop significantly at night. Heavy fog sits in the hollows of Kinord and Davan, and across Deeside.
The fog lifts to reveal a thawing dew-encrusted landscape.
Despite the cold, the spiders still hang on, producing ornate webs that shine in the morning dew.
With the webs covered well into the middle of the day, I do wonder how much use the webs have been at catching flies for the spiders to eat.
The spiders aren’t the only insects still hanging about in the cold. Several other insects can still be seen on the reserve, often concentrated to the open, sunny patches where they can heat up. If only the midges weren’t still about too…
Dung beetles can be seen regularly across the reserve. They seem eternally ill-fated as their rounded body often leads them to becoming stuck on their back, legs flailing. Being big, slow and clumsy makes them ideal prey at this time of year. They’re important in the diet of many predators, notably foxes; their iridescent blue wing cases and exoskeletons are clear in fox scat at in the autumn.
On several occasions this week, I’ve encountered geometrid caterpillars hanging down over the path from long silk threads.
The caterpillars would be a great find for the passing flocks of tits feeding up for the winter. When threatened, the caterpillars bungee down on a thread of silk, out of harms way. When the danger has passed, they hoist themselves back into the canopy to continue feeding.
A few black darters are still making most of the sunny weather, basking on the boardwalk across Parkin’s Moss. The moss is going through its own colour transformation as the bog myrtle begins to lose its leaves.
The reserve continues to produce lots of fungi of different shapes and sizes. These three are present around the visitor centre.
Also near the visitor centre, our brambles are only just coming into an edible (and delicious!) state.
There are still places available on the photography walk and the weather looks set to be perfect. You don’t need a fancy camera, come along to enjoy the colours and scenes of the season!
Over the next two weeks, Research students from the University of Aberdeen will be out recording information on the archaeology on and around Castle Island on Loch Kinord. The loch has a long history of human habitation, including 5 crannogs and a wealth of bronze-age archaeology. Here, the archaeologists are setting up GPS equipment to accurately record the locations of underwater features.
This week’s blog will finish with one of our more wonderful natural spectacles: the northern lights. It has been an excellent year so far for seeing the aurora borealis in Scotland, with good visible aurorae on several occasions. It hasn’t escaped the news or social media; aurora watching is becoming very popular indeed. Last week, the west of the country got a wonderful show on Wednesday but cloud over the east blocked out the view in the Northeast. Thursday night was clear and a subdued aurora was visible from Aberdeenshire.
If you fancy getting out into the cold, crisp, clear nights in search of a cosmic wonder, it is easier than you think! Lancaster University offer a free email alert service, along with apps and useful information at http://aurorawatch.lancs.ac.uk/
Alternatively, the National Oceanic and Atmospheric Administration’s Space Weather Prediction Centre offers a 30min forecast based on a fancy model called OVATION.
