It was very hot, so being near water appealed, and I hoped to see dragonflies out and about, but I only glimpsed one at high speed as it shot by whilst I was at the Tringford reservoir, though what I refer to as standard damselflies abounded and many were now flying tandem. I always assumed if they were blue they were male, if brown – female, but I caught sight of at least two occasions where I saw blue on blue or blue on blueheaded, brown damselflies, so I need to look into this assumption further.
On Tringford the tern were successfully fishing and were around in fair numbers with only the occasional gull coming in, whereas later on Marsworth, black-headed gulls predominated. I was invited to be rowed to the bottom end of Tringford in case I could get slightly closer to the egrets which had seemingly supplanted the grey herons of earlier seasons, but they were mostly far more nervous than herons and our rowing soon displaced them from a greater distance than herons. According to the water bailliff, the cormorants had taken a day off from their recent massive incursions, but he was not there during my visit and they still came in, so maybe his presence earlier this day had deterred them temporarily as I saw at least four during my stay, and one in particular seemed anchored to the middle tower, presumably using the extra height and the still waters to keep an eye on its prey. Certainly whilst we were on the water we spotted at least half a dozen fish clearly, keeping close to the edges of the weeds, as they made there way to the bottom end.
I moved to Marsworth and the canal, where I only saw a few tern, but did get a glimpse of a grey wagtail on the steep sloping banks of Startops. The brightness of the day and the heat seemed to keep the fish from feeding on Marsworth, where the fish though often right at the surface, took the flies rather than from the bait offered by the anglers, so most of those to whom I spoke were hoping for better luck towards evening.
What was noticeable was the abundance of tadpoles close to the shore in places, so if they can avoid massive predation, frogs could be having a resurgence later in the season. This day then, was to prove to be the day of the damselflies.
