For as long as I can remember, Britain has been known for its endlessly variable weather and the British people have been known for endlessly talking about it. However, the variability is becoming more and more extreme. Following the record-breaking heatwave in late May, we were plunged into a fortnight of 'unsettled' weather in June, with frequent showers (sometimes thundery) or periods of rain and daytime temperatures in the mid-teens. By the 4th, more rain had fallen in my garden than in April and May combined, and by the 10th more rain had fallen than in the whole of spring (March, April and May). This reflects how dry those months were, because the rainfall for June was only average at this point. Whilst the rain was welcome news for farmers (and my garden), it did restrict my activities and the activity of much of the wildlife that I watch, in the month that provides the most general wildlife interest of the year. At the time of writing (11th) it sounds as if the weather will improve over the next few days. I will split this month's effort into three sections: invertebrates, birds and mammals and flora.
Invertebrates
Butterflies can be on the wing for weeks or just a few days, depending on weather conditions. The vigorous activity prompted by the late May heatwave probably limited the lives on the wing of many butterflies to just a couple of days. By the 1st I was only able to find a single Adonis Blue on Church Hill. No other 'blues' were seen here, although I did encounter my first Marbled White butterfly, also on the 1st. A few Common Blues, including a 'blue' female, were seen on a local field early in the month. A Large Skipper, seen near the hospital on the 9th, was my first local sighting of this species. Otherwise, only a handful of Meadow Browns, Small Heaths and (rapidly declining now in numbers) Painted Ladies were seen up to the 11th.

Azure and Large Red Damselflies, probably emergent from local garden ponds, were seen near the house, but in what has been a slow season for dragonflies, none were seen on my local patch in the first half of June.

One puzzling sighting was of three apparent shield bugs, in different places, which I photographed but was unable to identify from 'Brock', or by looking online - one image is shown below. I checked back through my image archives from previous years and discovered that I had photographed an individual in 2024: again, I had been unable to identify it. Further investigation suggests that they may possibly be an invasive 'introduced' species, Brown Marmorated Stink Bug, which is a crop pest. However, this awaits further investigation.

Birds and Mammals
The wet weather was welcome news for ground feeders, particularly Blackbirds and Song Thrushes, which had found food hard to come by in spring due to the rock hard ground. Their ecstatic songs were noticeably more enthusiastic as the rain fell! Blue Tits often fledge their young at the beginning of June and two families (around 16 birds) were noted as I walked back from Hatchpen Farm on the 4th. On the same day I was delighted to note a Little Grebe with three tiny little chicks swimming on Phillup's Lake. Indeed, it was a family day there because a female Mallard had five young in tow and two pairs of Coot had five young (3+2) between them. The Coot, which are notoriously territorial, appear to have nested at opposite ends of the lake - I haven't seen any aggression between them to date.

Bird migration is over by the beginning of June, so local bird watching involves finding species that have escaped me to date in my local area. Having established in late May that my local Tawny Owls had once again bred successfully I returned to the area where they nest on the late evening of the 8th, armed with a camera in the hope of getting some photographs. The two juveniles duly obliged, although even with an ISO of 5,000 I was only able to manage one or two slightly blurred record shots (one below). They were still being fed by at least one adult bird. A welcome bonus was to find a Little Owl nearby, having first seen it being pursued by an angry Song Thrush. This was my first local record of Little Owl for over a year. There has been no evidence of successful nesting in recent years, although it is possible that the nest site is well away from public areas. A very active Badger sett is nearby and a Muntjac Deer was also seen here - what an evening hive of activity!

The following day I ventured to Hertford, where a summering female Goosander was being regularly reported. I found it on a weir in the centre of town, sharing its space with Mallard Ducks and Moorhens. When somebody started feeding the ducks with bread, it flew over apparently to join in (Tufted Ducks sometimes do this, although they probably just enjoy being part of a tribe and don't necessarily eat the bread). The bird was quite tame, presumably having been habituated to people. I wonder whether it is partially blind (no evidence from my images) or has some underlying physical problem (none seen) that prohibits it from 'normal' behaviour. Anyway, I wish it well! Whilst I was there I visited King's Meads, where a very active male Cuckoo was present and Reed, Sedge and Cetti's Warblers were all singing occasionally.

On The Heath (Lankester Hill), several Whitethroats and a single Lesser Whitethroat were singing when I walked across on the morning of the 11th and alarm calls from one particular group of bushes suggested that the young of one pair of Whitethroats may already have fledged
Flora
June is usually 'Orchid Month' on The Heath, but at the start of the month I could only see a handful of White Helleborines, which had 'gone over'. The rock hard ground did not give me hope for a good orchid season at the start of the month. However, after the heavy rain a single spike of Fragrant Orchid (image) had appeared on Church Hill on the 4th. Then on the 8th I saw a single spike of Lizard Orchid in the same area that had hosted two plants in 2025, which got me to wondering whether Lizard Orchids had always been present, but just missed by me.

Other plants benefiting from the wet weather included Agrimony, Wild Candytuft, Wild Mignonette, Red Clover and Hogweed.
