I spent the first week of June just wandering around the reserve at Attenborough. It was fairly quiet most mornings but Kingfisher activity was much higher than normal. Prior to this week I had only caught brief flashes of blue as a Kingfisher flew past on 4 occasions this year (out of about 75 visits), but two days in a row I saw 5 individuals and the male below even briefly perched above the path for me. Not the greatest of photos, but given how infrequently I see them at Attenborough I was just happy to see it.
The Blue Tits have fledged their first brood and quite large groups of juveniles could often be seen foraging for insects on the willows bordering the northern ponds.
In contrast, the Coots and Great Crested Grebes were still at the nest-building stage...
Several pairs of Common Terns nest on the reserve and adults often perch on the railings of the bridge across to the visitor's centre in the very early morning before there are any people around to disturb them.
Out on the water, resting on emergent vegetation, Red-eyed Damselflies are a common sight at Attenborough throughout June. The pair below were walking backwards down a Yellow Iris leaf with the female sytematically laying eggs as the pair got deeper and deeper underwater. They reached a depth of about 30cm before walking back up the stem to the surface and repeating the process on an adjacent leaf.
In the middle of the month I spent a couple of days in the Norfolk Broads looking for a couple of range-restricted dragonflies, neither of which I had ever seen before.
The first of these was the Scarce Chaser. As its name suggests this is a scarce species in Britain, and is found only in 6 separate populations in the southern England. The Norfolk Broads is one of these areas and it is reasonably common at places such as Strumpshaw Fen.
Males can only really be confused with Black-tailed Skimmers since none of the other blue chasers have a black tip to their abdomen. The dark wing bases and blue eyes, however, readily separate the two.
The dark markings visible on the sides of the abdomen of the individuals shown above are mating scars and can be used as a confirmatory field mark as the position of them is peculiar to Scarce Chaser.
Female and Immature male Scarce Chasers are highly distinctive and the combination of orange abdomen with triangular markings down the centre line and dark wing bases make their identification straightforward.
The other dragonfly I was hoping to catch up with was the Norfolk Hawker. This has an even more restricted distribution in Britain than the Scarce Chaser and is only found in the Norfolk and Suffolk Broads. In Europe it is widespread but is very locally distributed within its range.
In Britain, the Norfolk Hawker is unlikely to be mistaken for any other species, as it is the only brown-coloured hawker on the wing in June. Confusion with Brown Hawker (A. grandis) is possible towards the end of the Norfolk Hawker's flight season in July, but the lack of blue markings anywhere on the Norfolk Hawker should make identification easy.
Norfolk Hawkers are one of the easiest hawkers to photograph in Britain as they frequently perch on emergent vegetation in drainage ditches even when it is hot and sunny, unlike most other hawkers which never seem to sit still for a second.
This female was particularly cooperative and she spent about an hour in the late afternoon laying eggs on emergent vegetation below the water's surface.
Four-spotted Chasers were also common at Strumpshaw Fen, while other species seen (but not photographed) included Hairy Dragonfly, Broad-bodied Chaser, Emperor Dragonfly and Southern Hawker.
This Viviparous Lizard looked like it was heavily pregnant and was sunning itself on a boardwalk in the early morning.
The wet meadow grassland habitat on the reserve at Strumpshaw Fen is carefully maintained by the use of a small herd of Highland Cattle.
Early summer orchids on the reserve included Common Bee Orchid and Early Marsh Orchid.

A confiding Moorhen family provided a short distraction from the dragonfly photography...
