A Mixed Spring with one or two Surprises
From an avian perspective, Spring around Maldon was disappointing. Chiffchaffs were singing at Lofts Farm on 15th March and an early Swallow flew by at Heybridge Pits on the 16th, but there was little in the way of follow up passage. As ever, Lofts Farm was a good place to pick up Sand Martins, and then the first House Martins and Swift, and there was a smattering of passing Willow Warblers heard singing around the patch. But no Wheatears or Whinchats were spotted. There were some Whimbrels along the estuary and a couple of Little Ringed Plover sightings but the only half decent passage bird encountered was the drake Garganey seen by Tony Kennelly at Heybridge Pits on the 10th April. Fortunately, there were other wildlife distractions around the town!
Certain plants seemed to be everywhere. Red Dead-nettle was abundant, Greater Stitchwort widespread and Alexanders were seemingly along every roadside and sea wall.
Alexanders aren’t native, and it would be better if they weren’t so successful, but at least they deliver lots of early nectar that attracts a broad range of pollinators, from bees to dung flies! One notable fly of spring is the St Mark’s Fly, so named as they traditionally appear around St Mark’s Day, 25th April. They fly in a characteristic, sluggish manner, with legs dangling, and I was pleased to get a photo of one in flight.
Another fly I was pleased to see was an Alder Fly. Not rare but the first I had properly clapped eyes on. Their youngsters are entirely aquatic and are voracious predators. Indeed, a great many of the insects that we enjoy seeing around lakes and rivers- dragonflies, damselflies, caddisflies, mayflies- all have early stages that live underwater, demonstrating how vital it is that water quality is maintained, if the adults are to appear!
As ever, the first of the odonata to appear was the Large Red Damselfly– a nice distinctive species, often seen in gardens.
In April, Simon Wood discovered a patch of field at Lofts Farm that had been left uncultivated for a few months. For once, a whole load of traditional wild flowers had a chance to grow, and for a few weeks there was a chance to see the likes of Field Pansy, Common Fumitory and Henbit Dead-nettle. These belong to a group of species known as ‘arable plants’ that, due to modern agricultural practices, are rarely encountered these days.
The arrival of spring also encouraged our reptiles to get out and about. We have yet to locate a local Adder, but the Maldon ‘big three’ were all seen:
At Hazeleigh, there was a typically impressive spread of Bluebells. As well as providing an attractive display, they also provide habitat for other species, such as the micromoth Bluebell Conch.
Another example of inter-dependencies involves the Rivulet. Its foodplant is Red Campion. Unfortunately, campions are also eaten by Muntjac deer. In Hazeleigh we saw a lot of nibbled shoots but luckily there were still some blooms and Rivulet still seem to be hanging on.
Moths appear to be having a particularly tough time at the moment. This spring has been exceptionally poor for moth numbers at traps throughout south-eastern England. A post on the Recording Moths in Suffolk site by Neil Sherman gave a good summary of likely causes. An ongoing north-east airflow and clear nights have not helped and the cold, wet recent weather may have killed larvae and pupae. But possibly the main cause was the drought last summer that decimated larval foodplants.
This lack of moths was reflected at sessions at Hazeleigh Woods, where species counts were less than a half of the totals on the same dates in previous years.
Many of the spring moths that did show at Hazeleigh, were species that try to blend in to their surroundings.
But in contrast it was good to also see more striking species, including the always impressive Eyed Hawkmoth, as well as White Ermine and the attractive micromoth, Common Tubic.
Walking through the Maldon countryside in springtime there are always critters to spot, often surprisingly colourful…
Amongst the regular species, there were a couple of good finds at Heybridge Pits.
Simon Wood found a Large Garden Bumblebee and the first of several local Small Yellow Underwings was spotted feeding on Cornsalad, again at the gravel pits.
Finally, around the beginning of May, a couple of classy appearances at Chigborough helped restore Maldon’s reputation for birds. Now just looking forward to what the summer will deliver!
