Yesterday, 28th October, was one of those glorious sunny autumnal days where the air was fresh but the temperature was raised by bright sunshine, and I’d heard that the winter migrants were arriving on the lakes at Milton Country Park on the northern edge of Cambridge. So I took my camera to work and headed there for a stroll at lunchtime in the hope of snapping a teal or wigeon or perhaps a more unusual visitor. Several waterbirds were on parade including these cormorants:
Several migrant duck species were there too, including wigeon (Anas penelope, Dansk: pibeand), the duck with the chestnut head in the background of the cormorant picture is a male wigeon, tufted duck (Aythya fuligula, Dansk: troldand):
…and gadwall (Anas strepera, Dansk: knarand).
What I didn’t expect to see though, certainly not in the kind of numbers present, were dragonflies. It’s nearly November and the weather has started to get more autumnal but the warm weather up to now must have suited these airborne predators. In particular common darters (Sympetrium striolatum) were conspicuous, six at one time including two mating pairs. It’s always a treat to watch dragonflies but especially on a sunny day at the end of October, living uo to their name and darting about making a loud low frequency buzzzing noise .
The darters were sunning themselves on the fence lining a viewing jetty on the edge of a lake and while they were busy warming and copulating a migrant hawker (Aeshna mixta) was patrolling the adjacent reedbeds. All the dragons were pretty much oblivious to my presence unless I ventured too close then they would rise into the air, the copulating couple in tandem, only to return to pretty much the same spot with 30 seconds or so.
Every so often one or more of the common darters would chase the hawker away until it lived to its name and plucked one of them out of the air and butchered it whilst flying around our heads, scattering the inedible parts around us. After its aerial snack it headed up into the treetops and disappeared.
